Rains Extension Agent Bledsoe County UT Extension and 4-H Launch Yearlong Centennial Celebration Calendar year 2010 marks a century of University of Tennessee Extension and 4-H in Tennessee. That’s 100 years of educational outreach and service to the state’s farmers, families and youth to enhance their quality of life. Extension and 4-H in Tennessee predate the passage of the 1914 Smith-Lever Act through which Congress established a national network of professional agricultural agents and family and consumer scientists to help in the education and economic development of rural America. In 1910, two individuals were employed as county-based agents to help with cotton production and home canning, and in early 1911 the movement to help rural Tennesseans on the farm and in the home spread to six West Tennessee counties. On July 1, 1914, some 20 county agents, 22 home demonstration agents, and eight additional staff and faculty were organized under the Smith-Lever Act as part of the University of Tennessee Division of Extension. Today, as the outreach unit of the UT Institute of Agriculture, UT Extension operates an office in every county and delivers educational programs using research-based information to farmers, families, youth, and communities in both rural and urban settings. Educational programs range from gardening and landscaping to nutrition, animal health and family money management. The programs are available to all county residents often at no charge. “For 100 years Extension agents have represented a two-way link between Tennesseans and university specialists, scientists and researchers,” says Dr. Tim Cross, Dean of UT Extension. “That special relationship and the education and economic development that it fosters are the hallmarks of Extension,” he said. “Last year UT Extension had more than 4.8 million contacts with Tennessee citizens and the overall economic impact of these activities returned more than $343 million in estimated economic benefits,” Cross said. In announcing a yearlong Centennial Celebration of Extension and 4-H to faculty and staff, Cross emphasized the importance of commemorating 100 years of the organizations’ combined service to the citizens of the state. “While the economy continues to show little to no growth and additional state budget reductions are likely, a centennial only happens once in an organization’s history,” he said. “Recognizing this unique opportunity, we will observe our Centennial throughout 2010, acknowledging the anniversary during our everyday programs. We will acknowledge the many impacts we have made while being good stewards of our financial resources.” He hopes the celebration will also serve to increase awareness of UT Extension programs and therefore expand their outreach to new audiences, including youth. With the help of local adult volunteers, Extension's 4-H youth development program helps young people from 9 to 19 develop selfesteem, leadership and citizenship skills and gain knowledge in a wide range of subjects. From health to public speaking or photography or GPS tracking, 4-H programs supplement traditional learning with directed projects that encourage advanced education. With nearly 302,000 members statewide, Tennessee has one of the largest 4-H memberships in the nation. In addition to school-based and local activities, three 4-H camps throughout the state offer youth summer camping experiences and school-based outdoor science educational programs. Throughout 2010 UT Extension and 4-H will celebrate the organizations’ first century of accomplishments. What might those include? Just one example from the agronomic perspective is how Extension education and better farming practices have helped increase yields of corn in Tennessee from 25 bushels per acre during the early part of last century to an average of 139 bushels per acre in 2009. USDA statistics record that total corn production in the state was the same in 2009 as it was in 1910 (80.6 million bushels versus 82 million bushels). However, in 2009 only about one-fifth of the land was needed to produce a similar harvest (about 3.3 million acres in 1910 versus about 590,000 acres in 2009). Cross says each county will offer local activities that will offer individuals a chance to join the celebration. He hopes to involve all state residents in Centennial celebration events. “We will be integrating our celebration into our ongoing programs at the club, county and state levels all year long,” he said. “Everyone’s invited!” http://utextension.tennessee.edu/100years January 2010 2 January 2010 Plant of the Month – American Arborvitae Submitted by Dr. Susan Hamilton The American Arborvitae (Thuja occidentalis) is an easy and adaptable evergreen that can thrive in almost any landscape situation. Hundreds of cultivars have been introduced which allow this native, northeastern U.S. plant to fill almost any landscape niche. From miniature selections like ‘Mossy’ growing to just one foot tall and ‘Hetz Midget’ growing to two feet to ‘Green Giant’ growing up to 30 feet tall, these plants can fulfill many uses in the landscape. Cultivars also tolerate a range of soil conditions. American arborvitae can be found growing in the wild in swampy, damp conditions as well as in the dry cracks and crevices of rocky cliffs. It can equally tolerate a range of light conditions, thriving in light-shade to full-sun. One of my favorite features of American Arborvitae is its fine foliage texture. The evergreen, scaly foliage grows in fan-like sprays making for a soft, fine texture. Some stellar selections are valued for their striking foliage colors too like the bright gold foliage of ‘Yellow Ribbon’, ‘Lutea’, and ‘Sunkist’; the orange-bronze color of ‘Rheingold’ and ‘Fire Chief’; and the showy variegated foliage of ‘Sherwood Frost’ and ‘Wansdyke Silver’. I like to have a gold or variegated selection in my landscape to brighten up my winter garden. Many different forms along with varied sizes and colors allow for a range of landscape uses of American arborvitae. For a privacy screen and nice backdrop plant, you can’t beat ‘Green Giant’, ‘Smaragd’ ‘Emerald Green’, and ‘Degroot’s Spire’. Round and spherical forms like ‘Bowling Ball’, ‘Rheingold’, and ‘Hetz Midget’ make good foundation plants or good decorative container plants. Pyramidal forms such as ‘Emerald Green’, ‘Sunkist’, and ‘Yellow Ribbon’ can make nice specimen or accent plants. For ideal performance, I recommend growing American arborvitae in a well-drained soil in full sun to part shade. Foliage density will loosen up in too much shade. In hot and dry weather, periodic, deep waterings are advisable, especially when these plants are grown as foundation plants. Maintain a good three- to four-inch layer of mulch around the plants. Fertilizer and pruning are not required, which is another added benefit! January 2010 3 Some Arborvitae selections are valued for their striking colors Fun facts Another name for Thuja occidentalis is Arborvitae (the tree of life). Legend has it that Thuja was given this name because Native Americans used a tea made from the bark and foliage of this tree to save explorer Jacques Cartier and his crew from scurvy. Northern white-cedar is used widely as an ornamental tree. If pruned, it is capable of making a dense hedge. Thuja Greek "thyia" (for a juniper or a fragrant-wooded tree) from "thyo" (perfume). occidentalis western - Latin "occidere" (to set, as the sun).

But these freezing snowy days is a good time to spend indoors planning your summer garden. Peruse books, magazines, and catalogs for ideas and inspiration. Additional information is also available in publications of the University of Tennessee Extension, listed on the Web at http://extension.tennessee.edu/publications/default.htm. February is a good time to fertilize trees, shrubs and evergreens. It also is a good time to prune or shape evergreens. February through April is the ideal time to apply a combination of slow-release fertilizer and preemergent herbicide to control crabgrass in your lawn. Apply this combination before dandelions reach the puff-ball stage. Want to start your garden from scratch? February is a good time to start various annuals and vegetables from seed. This can be fun and it’s a great way to introduce youngsters (and the young at heart) to gardening. Seed starter kits are available in a variety of styles. Just follow the seed packet or seed catalog instructions on timing and method. February is the month for pruning. Make sure pruning tools are sharpened and cleaned in preparation for next month. 2010 UT Field Days Details for each will follow later • Organic Crops Field Tour at the East Tennessee Research and Education Center — Organic Crops Unit, April 29 at 7:30 a.m. • Tennessee Healthy Hardwoods at the Forest Resources Research & Education Center — Tullahoma, June 5 at 7:00 a.m. • Fruits of the Backyard at the Middle Tennessee Research and Education Center, June 15 at 8:30 a.m. • Summer Celebration at the West Tennessee Research and Education Center, July 8 at 10:00 a.m. • Steak and Potatoes Field Day at the Plateau Research and Education Center, August 3 at 8:00 a.m. • Turfgrass at the East Tennessee Research and Education Center — Plant Sciences Unit, September 16 at 7:30 a.m. • Pumpkin West at the Tennessee Research and Education Center, September 30 at 1:00 p.m. SPECIAL EVENTS • Fall Gardener's Festival at the Plateau Research and Education Center, August 31 at 10:00 a.m. • Heritage Festival at the Research and Education Center at Ames Plantation, October 9 at 9:00 a.m. • Fall Folklore Jamboree at the Research and Education Center at Milan, October 16 at 9 a.m. January 2010 4 Home Remedies and Fire Ants By Sheldon Barker I received an email the other day saying that club soda was a remedy for fire ants. The email even quotes Walter Reeves from the University of Georgia. The email said: Simply pour two cups of CLUB SODA (carbonated water) directly in the center of a fire ant mound. The carbon dioxide in the water is heavier than air and displaces the oxygen, which suffocates the queen and the other ants. The whole colony will be dead within about two days. Besides eliminating the ants, club soda leaves no poisonous residue, does not contaminate the ground water, and does not indiscriminately kill other insects. It is not harmful to your pets, soaks into the ground. Each mound must be treated individually and a Lateral view of a worker of the red imported fire ant, one-liter bottle of club soda will kill 2 to 3 mounds. Solenopsis invicta Buren. My first reply to the email was that it would not work. It would Photograph by: David Almquist, University of Florida simply make the ants move somewhere else. Since then the www.eXension.org www.eXentsion.org web site (a consortium of University Extension personnel from across the U.S.) began to collect information on this topic. Texas Extension entomologist, Elizabeth Brown tested club soda in a replicated study this summer (2009) with no results. She reported on her blog, "...pouring club soda onto a fire ant mound did not lead to the ants dying a horrendous death; it did however produce lots of impressive bubbling action.” I don’t think the fire ants would have been as impressed with the bubbling as Mrs. Brown (http://urbanipm.blogspot.com/). As for Walter Reeves he is retired from the University of Georgia Cooperative Extension Service and hosts radio and TV programs, and does not endorse club soda as a means to control fire ants. He suggests baits and mound treatments. (http://www.walterreeves.com/insects_animals/article.phtml?cat=21&id=1031) There are many household products which some claim will control fire ants. The list includes chlorine bleach, ammonia, gasoline, various detergents, plaster of Paris and drain cleaners. These are not labeled or recommended for control of any type of pest. Some of the choices are dangerous to the applicator, pets, children and wildlife. A few fire ants may be killed but they generally only cause the ants to move to another location. As a Master Gardener, the best recommendation you can make for controlling fire ants is what we call the “two-step” method. Using a bait followed 7 to 10 days later with a drench.

The public’s interest in vegetable gardening and the Sequatchie Valley Master Gardeners (SVMG) commitment to community service leads to a repetition of the successful Vegetable Gardening Workshops conducted in 2009. Topics and session titles are essentially the same as those used in 2009 in Pikeville and Dunlap. However, in 2010 there will be a single Workshop and the lengths of the various sessions differ slightly. A summary of the planned workshop follows. The Sequatchie Valley Master Gardeners in conjunction with Bledsoe and Sequatchie County Extension Offices will conduct a 4 hour Workshop on Saturday morning, March 27th at the Mountain Valley Bank Summit Room in Dunlap. The Workshop will begin at 8:30 AM and end at 12:50 PM with a 20 minute break. The first two sessions of 50 and 65 minutes, respectively, will be followed by the 20 minute break. The session immediately following the break will last 55 fifty minutes, followed by the final 60 minutes presentation. The program will conclude with five minute evaluation. 8:20 AM – 8:30 AM Registration & Distribution of Pamphlets 8:30 AM – 8:35 AM Welcome, Introductions and Preliminary Remarks Sophia Gabalski, Master Gardener and President SVMG Association Sessions and Schedule 1. 8:35 AM – 9:25 AM Site Selection, Soil Preparation, Planning & Planting Presenter – John Formby, Master Gardener 2. 9:25 AM – 10:30 AM Recommended Vegetables, Care, Maintenance & Harvesting Presenter – Jerry Dauer, Master Gardener 10:30 AM – 10:50 AM 3. 10:50 AM – 11:45 AM Break and Refreshments Disease and Pest Control in the Garden Presenter – Robert Wilson, Master Gardener 4. 11:45 AM – 12:45 PM Herb Gardening Presenter – Donna Cunningham, Master Gardener 12:45 – 12:50 PM Evaluation 12:50 PM Adjournment Advance publicity in Community Announcements in Sequatchie Valley Shopper, Bledsoe Banner, Dunlap Tribune and the banner on the Cable TV Weather Channel will hopefully result in a number of interested people from both Bledsoe and Sequatchie counties.

Rains Extension Agent Bledsoe County February 2010 Plant of the Month Submitted by Beth Willis The Windmill Palm, or Trachycarpus fortune, is an excellent choice for those who want a tropical feel in their landscape, but who do not have the luxury of a year-round tropical climate. This selection is very cold-hardy – a specimen in the UT Gardens shows no damage after an extended period of below-freezing temperatures. The Windmill Palm is an excellent choice for those who want a tropical feel in their landscape, but who don’t have the luxury of a year-round tropical climate. This selection, 'Bulgaria' is very cold-hardy. This attractive palm has large fan-shaped leaves that spread out from a single stem or trunk. It can reach 20-40 feet in the landscape, and trunk growth of up to a foot a year has been reported. The trunk is covered with a coarse mat made of the leaf bases, which remain on the stem even after the leaf has fallen away. The Windmill Palm is ‘dioecious’, meaning that it has separate male and female plants. Each bears large panicles of flowers in the spring. Female plants will develop yellow to blue-black fruits that ripen in autumn. Native to mountainous areas of Asia, the Windmill Palm has been cultivated extensively for centuries. The leaf sheath fiber of this plant is extremely strong, and it has been used for making ropes, sacks and coarse cloth. Throughout the world, it is highly sought-after by palm enthusiasts as an ornamental. In the United States, it has become a popular landscape specimen in much of the southeast as well as mild areas on the east and west coasts. Windmill palms prefer a fertile, welldrained soil but can tolerate other conditions so long as it is not in a continuously soggy site. It will do well in part-shade to full sun. It can even be planted in containers. If planting in Zone 7 or above, a sheltered site is recommended. Once established, specimens are fairly drought tolerant, although growth will slow. They are also wind and salt tolerant, which make them suitable for coastal plantings. The pictured cultivar, ‘Bulgaria’ tends to have smaller leaves and a tighter habit than the species. It has been propagated from specimens in Plovdiv, Bulgaria, which have survived repeated exposures to temperatures as low as 0 degrees F. Other forms and related species are commercially available as well. The ‘Taylor form’, for example, has very droopy leaf tips, while T. nanus is a dwarf form. Any of these would bring that distinctive tropical feel to your landscape, although they do have some variability in cold hardiness. February 2010 2 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson March Gardening Tips “April showers bring May flowers,” for the gardener that means things have to be ready. March is the time to sow indoors those flowers especially summer annuals (if you plan to start your own). Follow catalog or seed package directions. This is the time to divide and transplant clumping perennials such as daylily and hosta. You will also need to be ready to fertilize established perennials as soon as new growth appears Remember to follow soil test recommendations. No soil test! You might think about taking one soon, before the busy season at the lab. Transplant any free-seeding perennials such as hellebore or coreopsis as they appear. March is also the time to cut-back ornamental grasses to just above their growing crown. Divide any thick and overgrown clumps and fertilize established grasses as soon as new growth appears. Set your mower on it highest height and mow your ivy, vinca, and monkey grass ground covers to easily remove old foliage. Finish pruning fruit trees this month, before the buds swell. Be sure to get these cool-season annual veggies in this month and the sooner the better! Spinach, head and leaf lettuce, collards, turnip greens, onions, beets, broccoli, cabbage, Brussel sprouts, cauliflower, carrots, eggplant, early potatoes, radish and Swiss chard can be direct seeded or transplanted into the garden. March through April is an ideal time to apply a combination of slow-release fertilizer and preemergent herbicide for crabgrass control to your lawn. You want to apply this combination before dandelions reach the puff-ball stage. Pruning Gardening Tips from Jason Reeves, Horticulturist, UT Gardens in Jackson March is the ideal time to cut back the following garden plants: Miscanthus (maiden grass), Pennisetum (fountain grass), Muhlenbergia (muhly grass) and Nassella (Mexican feather grass) to 3 inches to 6 inches above the ground. Old growth on Helleborus (Christmas and Lenten Rose) before new growth appears. Liriope (Monkey grass) before new growth appears. Use a string trimmer for larger areas. Hardy fern, including evergreen forms, before new growth appears. Epimedium (barrenwort) flowers early so don't delay. Acorus (sweet flag) only if the winter has browned the foliage. Prune out older branches on Cornus sericea (red twig dogwood) to encourage new growth with bright bark. Knock Out™ roses or other shrub roses that have grown bigger than you desire. Cut well established plants back 2 to 3 feet shorter than the height you desire. Late March is the ideal time. Older branches on Callicarpa (beautyberry) to encourage new growth that produces more berries. Rejuvenate overgrown Nandina (heavenly bamboo) by cutting back to a few inches on the outside, leaving taller canes in the center, staggering the heights. Limb up and remove cross branches as needed on trees and tree type crape myrtles as needed. Never top trees or crape myrtles. Look closely at grafted plants and remove all growth below the graft. Commonly grafted plants to pay close attention to include witch hazels, contorted filberts, weeping cherries, weeping mulberries, dogwoods, fruit trees, crab apples, and Japanese Maples. March is the best month to carry out drastic pruning on overgrown hollies. February 2010 3 “A Growing Obsession: Rare Seeds” “A Growing Obsession: Rare Seeds” was the title of a February 10, 2010 Wall Street Journal Article by Anne Marie Chaker. This is an excellent overview of the seed exchange process and can be found at http://online.wsj.com/article/SB1000142405274 8704820904575055181332462128.html?mod=W SJ_LifeStyle_Lifestyle_5#articleTabs%3Darticle Seed exchanges “are groups formed by garden clubs or plant collectors whose members harvest seeds from their own plants and donate them to the exchange.” There is little or no cost when gardeners order seed from the exchange. What is the appeal of these exchanges? Well, they frequently offer unusual varieties of plants not typically found in catalogs, maybe a species grown by few collectors, or an "heirloom" variety. Late winter is the time many gardeners are planning for the 2010 growing season and March is a time many vegetables are started from seed to be ready for a spring transplant. Thus, the next few weeks are the busy season for seed exchanges. Ms. Chaker comments that part of the enjoyment of the exchanges is surfing the seed exchanges and recognizing names and gardens where donations come from. Yes even well known gardens use seed exchange. For example, the New York Botanical Garden has listed with The North American Rock Garden Society more than 100 seeds from its expeditions to the countries of Georgia and China in 2005 and 2007. The article notes that the Smithsonian's Mary Livingston Ripley garden has donated to the Hardy Plant Society/Mid-Atlantic Group seed exchange several varsities’ and this year they donated seeds of a South African foxglove. Some exchanges specialize in a particular plant, letting members explore unusual varieties. The Kansas City, MO bases, The Species Iris Group of North America exchange is an example of a specialized exchange. One variety included on the exchange is the snake-bane iris. The snake-bane iris is a native of China believed to repel snakes, and is extremely rare in the U.S. According to James W. Waddick, The Species Iris Group of North America exchange's cochairman, the exchange is not just for iris snobs, he says, adding, "There are some people who want to have a 20-foot row and don't want to pay for plants when you can just buy a packet of seed." To take part in an exchange, gardeners harvest seeds and mail in their seed donations. The organization then publishes a catalog listing contributions. Members then make their pick and depending on availability, receive anywhere from a handful to hundreds of seeds. The cost may be as little as 50 cents or less—a fraction of what commercially sold seed packets can cost. Sometimes there are limits on the number of seeds members can order. Annual dues are often required and can run from as little as $5 to $40. Some web sited such as blossomswap.com also host seed-trading forums, which do not require membership fees. These homemade listings may not have many of the showy hybrid varieties commercial catalogs offer and that appeal to many gardeners. On the other hand, gardeners interested in species plants or “heirlooms” will find plenty of variety in these seed-exchange listings. Charles Cresson, a Swarthmore, Pa gardener who oversees a garden that has been in the family since 1883, says, “A good plant should be shared, and a rare plant should be shared… Its survival depends on it." Mr. Cresson expresses one of the great things about gardening, sharing. Six seed exchanges were listed in the article are listed below with web address for more information: American Penstemon Society www.apsdev.org Hardy Plant Society/Mid-Atlantic Group www.hardyplant.org North American Rock garden Society www.nargs.org Seed Savers Exchange www.seedsavers.org Society for Pacific Coast Native Iris www.pacificcoastiris.org Species Iris Group of North America www.signa.org February 2010 4 What is it? A The Brown Recluse Spider The brown recluse Loxosceles reclusa Gertsch and Mulaik is a medium-sized spider belonging to the Order Aranea (spiders) and the Family Loxoscelidae (the brown spiders). The adult body ranges from 7mm to 12mm in length (1/4 to inch) and 3mm to 5mm wide (1/8 to under 1/4 inch). The legs span an area roughly the size of a quarter to a half-dollar. The color of the brown recluse varies from a light yellowish brown to a dark, reddish or chocolate brown, but most are light to medium brown. Short hairs densely cover their body, and the male abdomen is generally smaller than that of the female. The second pair of legs is longer than the remaining pairs in both sexes. Three pairs of eyes are arranged in a semicircle. Since most other spiders have eight eyes, this feature alone can eliminate many specimens suspected of being a brown recluse spider. The most distinguishing characteristic is the violin-shaped marking on the carapace (the top of the body directly above the legs). Although variable, the violin-shaped marking is usually much darker than surrounding areas and may appear longitudinally lined. In some individuals, the size of this violin-shaped marking may be considerably reduced. Other spiders may have a violin-shaped marking. The best identification feature for the brown recluse is the semicircular arrangement of the three pairs of eyes. Contact your county Extension agent to identify a suspected brown recluse spider.

March 2010 2 March 2010 Plant of the Month Sedum Submitted by Matthew Morrow As the weather begins to warm, we are turning our thoughts toward annuals and other warm weather plants. Sedum are most often considered to be warm weather plants, but the genus will surprise you in the height winter and even now as the days are growing longer. The first time I noticed the beautiful winter interest of sedum, I patted it on the head and whispered, “Nice going, little guy.” Moving past the fact that I anthropomorphize my plants, many species of sedum will add a sparkle of color to your cold weather landscape. Not all of these plants look their best in winter, and some disappear for the coldest months. However, you can trust some species to hang around and look spiffy in the cold weather. Sedum rupestre ‘Angelina’ is the first of these. This vigorous little ground cover has become very well established in garden centers and gardens these last few years. The chartreuse foliage turns a vivid mix of orange and light-plum in the winter months, as if it is setting itself aflame to keep warm. Less well known is S. bithynicum (syn. S. palladium var. bithynicum), or Turkish sedum. This 2 inch high succulent can be downright aggressive, but the ice-blue color of its foliage makes the rampage seem charming. It is easily pulled. Tight clusters of foliage make the sedum appear to be a carpet of little balls that change from blue to a very interesting pink when temperatures drop. This sedum planted around a red twig Dogwood (like Cornus sanguine ‘Winter Flame’) can be striking. S. album is an old favorite that keeps a solid green all through the winter. ‘Coral Carpet’ turns red in the summer. For a nice red-purple in the winter, many S. spurium cultivars are available. ‘Dragons Blood’ is a popular choice, although it struggles when the weather gets hot and humid. All sedum require excellent drainage, a good amount of sun and little water in winter. The sedums mentioned are suitable for zones 3 to 8 except for S. spurium, which has a range of zone 3 to 7. You should also try to keep leaves from accumulating on top of them, or the plants may rot. Sedums propagate easily, so mix and match them and have some fun. Sedum are most often considered to be warm weather plants, but the genus will surprise you in the height of winter and even now as the days are growing longer. This mixture of sedum is on display at the UT Gardens at the West Tennessee AgReseach and Education Center in Jackson. Photo by J. Reeves March 2010 3 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson April Gardening Tips April is the month that gardens and gardeners alike really spring to life. Buds and blooms invigorate the plants and their caretakers. The University of Tennessee Institute of Agriculture recommends gardeners perform the following tasks to keep their landscapes looking their best. Spring Bulbs As spring-flowering bulbs finish blooming, remove the spent flowers and any developing seed pods. This will permit the flower to spend its resources on making bigger, more plentiful flowers next year. Do not twist, braid or cut off the foliage. The leaves are gathering energy to store in the bulb for next year's growth. If you must remove the foliage, wait until it is mostly brown or yellow, then cut it off cleanly at the ground. Bulbs will appreciate a sprinkling of a bulb-formulated fertilizer applied just as flowering is complete. Summer Bulbs Summer-flowering bulbs can be planted in mid to late April in East Tennessee and somewhat earlier in Middle and West Tennessee. Dahlia, gladiolus, tuberose, fancy-leaf caladium, elephant ear, amaryllis and canna will add color, fragrance and texture to the summer garden. Caladiums and elephant ears thrive in shade, while all the others need full sun (or at least half a day) to bloom well. Since these bulbs need to grow quickly to provide summer interest, prepare the planting bed by deeply tilling, incorporating organic matter and adding bulb fertilizer. Crush any clods, remove rocks and debris, and then rake the bed smooth and level. Crowning the bed (making the center slightly higher than the edges) improves drainage. Follow the directions on the bulb package to determine the correct planting depth and spacing. Lawns Cool-season grasses such as fescue, bluegrass and perennial ryegrass should receive their second fertilizer application of the year in April. Turf experts advise applying half to one pound of nitrogen in March and again in April. Cool-season grasses should not be fertilized until September. Warm-season grasses such as Bermudagrass, zoysia and centipede should be fertilized just as the grass begins to green up. Apply one pound of nitrogen per 1000 square feet. Repeat this application in May and June. If you need help choosing or applying a lawn fertilizer, ask your county Extension agent or a master gardener. You can do much to reduce weeds and improve the appearance of your lawn by mowing at the correct height for the type of grass you have and mow frequently with a sharp blade. Turfgrass experts recommend these mowing heights: Kentucky Bluegrass - 1.5 to 2.5 inches Turf-type Tall Fescue - 2 to 3 inches Fine Fescue - 1.5 to 2.5 inches Perennial Ryegrass - 1.5 to 2.5 inches Common Bermuda - 0.75 to 1.5 inches Hybrid Bermuda - 0.5 to 1.5 inches Zoysia - 0.75 to 1.5 inches Centipede - 1 to 2 inches Shrubs Azalea, forsythia, lilac, weigela, flowering quince, spring-flowering spireas and other shrubs that flower very early in the year can be pruned as soon as flowering is over. Do not delay because these shrubs make next year's flower buds during the summer. No fertilizer may be needed, but these shrubs can be fertilized before or soon after flowering. Shrubs and trees are more often over-fertilized than under-fertilized. Putting out fertilizer when none is needed tends to make trees and shrubs more susceptible to insects, disease and drought. If you have not pruned your butterfly bush (Buddleia davidii) by now, do it this month. The common butterfly bush should be cut down each year to within six or 12 inches off the ground just before or soon after new growth begins. Butterfly bushes are rapid growers and only produce flowers on new growth each spring. In addition, the annual cut-back will produce larger flowers and maintain manageable shrub size. A mature bush can be cut completely down and still grow back to its full height within three to four months and flower profusely. March 2010 4 Azalea Lace Bug Inspect evergreen Azaleas for lacebug damage. This common Azalea pest feeds on the growing in the water, mud or pots along the edges of the pond. Clean fallen leaves from shrubs near the water. Prune overhanging branches to allow the most sun to reach the water surface. If you feed your fish, begin doing so when you see them actively swimming. Fruit Trees Stippling caused by feeding by Azalea lace bug on deciduous azalea http://woodypests.cas.psu.edu/PestDiagnosis/Azalea.html underside of leaves and gives a whitish, pale or stippled appearance to the top side of the leaf. The bugs are tiny and hard to see, but they leave dark brown dots or flecks on the underside of the leaf. If left uncontrolled, lacebugs will cause the plant to be unattractive, decline and perhaps die. Begin by evaluating the growing conditions of your Azaleas since a well-grown plant is significantly less troubled by these insects. A safe and effective way to destroy these insects is to spray the underside of the leaves with a horticultural oil or an insecticidal soap. Thorough coverage is necessary and must be repeated at least once (within ten days to two weeks). Water Gardens April is a good time for pond cleaning. Skim the surface to remove any fallen leaves or other debris. Cut back and remove debris from plants While fruit trees are blooming, refrain from spraying insecticides to spare the bees pollinating the flowers. Within a week after the flower petals fall, resume your regular fruit-tree-spray program. Peach, plum and cherry trees may be sprayed shortly after petal fall to control fungal diseases like brown rot, rust and leaf spots. Ask an informed salesperson at your local garden center to recommend a fungicidal product or contact your local county Extension agent or a master gardener. Vegetable Gardens You can still plant cool-weather vegetables this month. Onions may be planted directly in the garden from sets, small onion bulbs, purchased from the garden center. Push the onion set into soft, fertile garden soil until the top is just below the soil surface. Onions do not compete effectively against weeds, so be prepared to hand weed your onions. Broccoli, cabbage and cauliflower plants should still be available. Sow seeds of lettuce, leafy greens, beets, carrots and radishes directly into well-prepared soil. Set out spinach plants or grow your own from seed. Beans and corn can also be planted. If you grow the "supersweet" varieties of corn, wait until May 1 to sow the seed, or until the soil is warm where you live. Warm-weather-lovers like tomatoes and peppers should not be set out until the last expected frost date is well past and the soil is getting warm (May 1-15 in East Tennessee). March 2010 5 The Quickest Growing Vegetables Source the Garden Guides http://www.gardenguides.com/100307-quickest-growing-vegetables.html Waiting for harvest can be one of the more tedious parts of gardening. Instant satisfaction can be had when you're perusing a farmer's market or grocery store, but not when you're growing things yourself--those juicy tomatoes you crave may well take months to get into your sandwich. But there are many vegetables, warm- and cool-season, that take less time to grow than others, making them particularly suitable for children, and for mixing with longer-germinating crops. Onions According to the University of Tennessee Extension, many onion varieties can take as little as 30 days or up to 60 to mature enough to harvest. They can be planted very early, in February or March, or as a fall crop. The Texas A&M University Horticulture Department explains differing onion types form bulbs at different rates, depending on the length of the days, and all require more water the closer they get to harvest. Turnips Turnips grown for their greens, rather than roots, can be planted in March and take between 30 and 40 days to mature. Heirloom Organics says optimal growth is dependent upon a site with deep, loose and fertile soil. Summer Squash Summer squash, once seeds sprout and plants become established, grows prolifically if given enough water and sun. The fruit is ready to be harvested from the sprawling plants between 40 and 50 days after planting in early summer. The University of Illinois Extension advises picking fruit before it matures and the rind hardens, about four to eight days after flowering. Cucumber Cucumber can be harvested around the same time as summer squash. Vegetables being grown for picking or slicing can be picked as soon as 50 days later, before they reach the yellowing stage, the Ohio State University Extension states. Bush Beans Healthy snap bean plants in bush varieties produce a large crop within about 50 days, after they bloom. They work well planted successively from April through June and grow best when there is a constant moisture supply, Fort Valley State University claims. Radishes Radishes, often grown as an early spring or fall crop, are one of the quickest growing vegetables. They will reach maturation as soon as 35 days and serve as a good "intercrop" among longer-maturing vegetable plants, says Heirloom Organics. Leaf Lettuce Another fall vegetable, leaf lettuce can be harvested within 40 to 50 days after planting in July, August and September. It is cold hardy, but hot weather can stunt growth and make leaves taste bitter, according to the University of Illinois Extension March 2010 6 Ready to start your garden? By: Carol Reese, Ornamental Horticulture Specialist -Western District These vegetables don’t mind if it’s not yet spring…or Cabbage, cauliflower, kale and other cole crops are cool with cold weather…or Cabbage, kale, cauliflower and carrots are cool with the remaining cold weather I longed for warmer weather and now it has me frightened. I’m still gun shy after the Easter freeze of 2007. If you’ve forgotten, we had one of the warmest Marches on record, followed by three nights in April with temperatures that dropped into the ‘teens. The resulting damage was horrific and something I hope to never see again. Remember that we have about five weeks to go before our average last frost date - around the middle of April. I’ve seen people in shorts this week, and I’m afraid the eternal optimists, or the woefully ignorant may troop out to the garden with tomato plants. That said, you can plant cool season vegetables now. Some that you can easily grow are also the expensive ones at the grocery store, such as broccoli, cauliflower and Brussel sprouts. My brother Dan says every year that he doesn’t plant enough of these, and every year he plants more and still complains that he doesn’t grow enough of these. Also plant your greens - lettuce, mustard, spinach, chard and kale. Turnips provide both greens and edible roots. Root vegetables such as carrots, potatoes and radishes are also on the early spring agenda. For carrots to develop well, you need loose, fluffy, friable soil. George Foster at Green Thumb Nursery in Lexington says if you don’t have that kind of soil, you might plant carrots in a raised bed, mixing your garden soil with compost, or a porous potting medium. I’ve seen lots of evergreen shrubs with dead foliage, or even completely defoliated from winter injury. Don’t assume these should be cut back. The leaf loss does not mean that the wood is dead, and the odds are quite good that the plant will flush new growth normally once spring has “sprung”. By late May, it should look like “its old self”. Still, this is a good time to prune back evergreens that have grown too large, though you know that I’m generally against that practice. If it’s too large for the site, I’d say you should consider moving it, or limbing it up into a tree form. I would hate to be sentenced to controlling a plant’s size for the rest of its duration in my landscape. There are a few plants though, that I do recommend giving a good “make-over” with your pruners. Nandina is one. The common species of Nandina domestica most often found around older homes, often develops into a group of leggy stalks, each with a topknot of foliage. Starting a few inches above the ground, cut these stalks at a variety of heights, leaving the tallest in the middle, or tallest toward the back if the plant is viewed from only one side. New growth will flush thickly from these pruned stalks and flowers will develop on the new growth, resulting in red berries by the time fall arrives. The final result will be a voluptuous nandina where you once had lanky. I also see lanky rose of Sharon, aka althea or shrubalthea. This plant also blooms on new wood, so give it a tip pruning, or even a thorough reshaping and you’ll see a big increase in flowers. Leave your hydrangeas alone, unless you have Hydrangea arborescens, which blooms on new wood. If you have the old fashioned pink, blue or purple hydrangea, it is likely to be Hydrangea macrophylla or serrata, and the flower buds were formed last summer. Pruning now will cut them off, insuring that you have no flowers or very few.

The flowers come in almost every color and can be nodding to upright, depending on the species. My favorite of the group is Aquilegia canadensis. Sometimes called Eastern or Canadian columbine, A. canadensis is native to most of eastern North America and can be found growing wild in at least 37 states and much of Canada. It may not be as showy as some of its kin, but its flowers have a certain grace and elegance, making it one of my favorite spring flowering plants. The drooping, bell-like one- to two-inch reddish and yellow flowers are produced in April and May on twoto three-foot stalks. Many do not realize that they make good cut flowers. Hummingbirds find these blooms irresistible; however, as a member of the Ranunculus family, columbine is less appetizing to deer and other pests. In the wild, plants are found in a range of growing conditions, from moist semi-shady areas to dry rocky bluffs. In the garden, they perform best in full sun to partial shade and in moist well drained average garden soil, but will grow in a wide range of soils as long as the drainage is good. Columbine’s glaucous blue-green compound leaves are held in groups of three by long petioles giving the plant a beautiful frilly Sometimes called Eastern or Canadian columbine, A. canadensis is native to most of eastern North America and can be found growing wild in at least 37 states and much of Canada.

As compared to other species and hybrids, A. canadensis is less susceptible to leaf miners, which do little longterm harm but can make the foliage unsightly. Plants freely self-seed and will naturalize in the garden. When starting seed indoors, germination can be improved by sowing the seed in a good potting media and placing in a refrigerator for 6 weeks before moving to a warm location. From seed they will flower the second year and live for three to four years in the garden. April 2010 3 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson May Gardening Tips May is the month to get everything planted. Be sure to mulch plants and keep things well watered since young, unestablished plants can dry out and die quickly. After getting everything planted and mulched, don’t forget to apply a pre-emergent herbicide to prevent an invasion of summer weeds. Preen is the most popular brand on the market that can be used with just about any plant. In addition to planting, May chores abound: As soon as spring-blooming shrubs have finished flowering, prune and shape the plant if needed. Watch for bagworms on junipers, cedars, arborvitae, and white pine. If you have had a grub problem or other insects in your lawn, apply a grub-controlling insecticide or one labeled for the insects you want to control. May is strawberry-picking month. Stock up on ice cream and whipped cream! Spray fruit trees and grapes early in the month with preventative fungicides. Keep tomatoes pruned and tied as they grow. Be careful not to over fertilize, or you will increase flower and fruit drop. Tie the leaves over small developing heads of cauliflower to keep it tender, mild flavored, and white. Water everything that is newly planted. Check every day for adequate moisture until the plants establish themselves in your garden. Deadhead or prune back spent flowers on your perennials. This simple process will keep those perennials blooming beautifully throughout the season. Stake tall-growing perennials to prevent them from lodging (falling over). Use a light-weight soil mixture to grow annuals in containers. Keep the plants well watered, because these plants dry out fast! Also, be sure that your containers have adequate drainage holes. Mulch around newly planted trees and shrubs. This simple practice reduces weeds, controls fluctuations in soil temperature, retains moisture, prevents damage from lawn mowers and looks attractive. When planting summer annuals, consider pinching and removing the flowers to stimulate branching and the production of many more flowers. April 2010 4 Gardeners Beware of Diseased Tomato and Pepper Plants Steve Bost From The TMG list serve Due to recurring problems with serious diseases on tomato and pepper plants, the University of Tennessee Institute of Agriculture is encouraging Tennessee gardeners to buy their tomato and pepper plants from local greenhouses. Dr. Steve Bost, a plant pathologist with the UT Department of Entomology and Plant Pathology and UT Extension, says bacterial spot disease is often found in tomato and pepper plants. “Last year, a major epidemic of late blight disease of tomato and potato occurred in much of the eastern half of the country as a result of infected tomato plants,” he said. “Both plant diseases are very difficult to control and, under rainy conditions, satisfactory control is impossible.” These are blight diseases that cause the leaves to die, thus starving the fruit and resulting in fewer, smaller fruit. Spots and rots can also occur on the fruit. Bost says the easiest and most effective means of controlling these diseases is to buy disease-free transplants in the first place. “These diseases have not been seen in plants produced by local greenhouses, so before you purchase a plant from a garden center, look at the tag or ask where it came from. Also, many local greenhouses sell directly to the public.” The expert further says you can’t always tell whether a plant is diseased by its appearance. “A plant may show few or no dark spots on the leaves at the time you purchase it,” he said, “but it may still be infected or contaminated.” If your tomatoes or peppers had bacterial spot last year, clean up and bury old plant debris. If suspicious symptoms begin to develop on your plants this year, spray with a copper fungicide every week and don’t wet the leaves when watering. Look for brown, pinhead-sized spots on tomato leaves. On pepper leaves, the brown lesions can be slightly larger and some of them run along the margins of the leaves. Another reason for keeping these diseases out of our kitchen gardens, says Bost, is to preserve the viability of our local vegetable farmers’ operations. “Our own farmers’ livelihoods are at stake,” he emphasizes. “These diseases can ‘escape’ from your garden to other gardens or commercial fields.” The result Bost says would be that more pesticide sprays would be needed and crop harvests would be reduced. “So, do yourself, your neighbors, and the local agricultural economy a favor – buy tomato and pepper plants from local greenhouses,” Bost says. Bacterial spot is a serious disease of tomato, but it's not always apparent in young plants.

H. Fred Dale J. C. Rains Sheldon D. Barker Extension Agent Sequatchie County J. C. Rains Extension Agent Bledsoe County May 2010 Plant of the Month Ninebark Submitted by Carol Reese Reading through my already well-thumbed new edition of the Manual of Woody Landscape Plants, I was surprised to see a quote from Dr. Michael Dirr, esteemed woody plant guru, claiming that almost anything was better than a ninebark. He then went on to say that he’d written that decades ago, and that the newer cultivars had changed his mind. True, the native form of ninebark, Physocarpus opulifolius, is a rangy plant with a brief bloom period, followed by a slightly longer show of colorful seeds. There wasn’t much to write home about, certainly. It was the introduction of forms with bronze to purple foliage that made the plant a vibrant player in the landscape for the length of the growing season. Golden-foliaged forms have been in the trade for some time, and in cool climates, they are worthy garden additions. In hotter regions, however, the bright hues fade so fast you might feel the plants are wasting space. The new dark-foliaged forms have much more to commend them. Of the several new dark-foliaged forms, if I were forced at gunpoint to pick only two, they would be ‘Summer Wine’ and ‘Coppertina’. ‘Summer Wine’ has a spreading, waterfall growth habit similar to an old fashioned spirea. The toothed, slightly lobed leaves flush in late spring, and though the purplish tint is apparent, it takes a few weeks of sunlight for the color to ripen and intensify. Flowering umbels of palest pink emerge from the leaf axils and generously stud each weeping branch. Perhaps even more showy are the umbels of red seed capsules that follow. Usually a new flush of growth covers these within a few weeks, so you are left with a graceful shrub of rich dark foliage. Many purple plants turn a muddy brown in the heat of the south, but the color of 'Summer Wine’ just gets richer. ‘Coppertina’s growth habit differs slightly. It’s definitely a spreader, wider than tall, but the limbs don’t seem to have the same downward spill as ‘Midnight Wine. Newly emerging bronze foliage has limey gold tints in the center, but eventually the entire shrub is a rich dark copper. Flower and seed display is similar to ‘Summer Wine’. If you find a form called ‘Diablo’, be warned that it is a much, much larger plant, and wishes to grow in a stiff, upright “V.” I didn’t care for it, until I came upon it at Chanticleer Gardens limbed up into a tree form, as you might a crapemyrtle. This revealed the a peeling white bark, which contrasted beautifully with the dark foliage and slightly pinker flowers. Lovely! These plants are of easy culture. Though they are quite tolerant of shade, the best foliage color and bloom display will occur in sun. They accept a wide range of soil, except overly wet. The new dark-foliaged forms of ninebark are showy additions to the landscape. In this photo by C. Reese, the warm hue of ‘Coppertina’ foliage is brightened by clusters of red seeds that follow pale peach-colored flowers. May 2010 2 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson June Gardening Tips There’s no shortage of work to be done for your lawn and garden in April. Here’s a checklist of a few chores recommended by Dr. Susan Hamilton, director of the University of Tennessee Gardens: Keep watering newly planted plants. Also, as temperatures rise and plants mature, keep containerized plants well watered. Watch for Japanese beetles this month, especially on hibiscus and roses. Cut back perennials after their first bloom period. Garden phlox, heliopsis, veronica, echinacea, and platycodon will rebloom. Direct seed sunflowers in your garden. Stagger their planting by every week or two through July, and you will have flowers until frost. Divide bearded iris soon after flowering. By dividing now, the plants have time to get established, increasing the chance of flowers next year. Fertilize azaleas, pieris, mountain laurel and other acid-loving species one more time before August 15 using an acid-based soluble fertilizer containing iron. Spray against sap-feeding lacebugs. Target the underside of leaves with an appropriate insecticide, insecticidal soap or a summer oil. Be sure to follow label directions. Watch for fall web-worms with their webbing at the ends of branches. Prune out the webs that can be reached. Various insecticides are available if chemical control is desired. Spray a multipurpose fruit tree insecticide and fungicide to prevent any insect and disease problems. Spray until 10 days before harvest. Remove all root suckers at the base of all fruit trees, particularly apple and pear, and all thick water sprouts shooting up straight on the branches. Also remove any diseased, dying or insect-riddled wood. Keep tomatoes pruned and staked or in cages. Prevent blossom-end rot of tomato by providing deep and regular watering with drip irrigation or soaker hoses in addition to mulching for water conservation. Fertilizing with calcium nitrate rather than agricultural grade 10-10-10 fertilizer also helps. Harvest cucumbers, green beans and summer squash when they are ready. If you stop picking, production will halt. Seed, sod or plant plugs of Bermuda grass or other warm-season grasses like zoysia. Fertilize and de-thatch warm-season lawns As of May 7, 2010 there were 421.78 hours of volunteer time recorded by Sequatchie Valley Master Gardeners. The value of these hours is $8794. Thanks to the 13 you have recorded hours thus far.

May 2010 3 Invasive Weed Grass Threatens Native Habitats Mark Atwater, Weed Control Unlimited, Inc., Bugwood.org A non-native weed, often inadvertently sold as ornamental grass, is spreading throughout the Southeast and threatening native plants and animals alike. Cogongrass (Imperata cylindrica) is sometimes sold by nurseries as the ornamental cultivar Red Baron bloodgrass or Japanese bloodgrass, says Beth Long, a plant pathology specialist with University of Tennessee Extension. “Cogongrass can lose its red color and quickly become a problem weed,” Long said. “It has been found in Alabama, Florida, Georgia, Louisiana, Mississippi, South Carolina, Texas and Virginia.” This perennial, thick-rooted grass grows from 2 feet to over 4 feet in height. The leaves are about an inch wide, have a prominent white midrib, and end in a sharp point. The flowers are arranged in a silvery, cylindrical, branching structure between 3 and 11 inches long and 1.5 inches wide. Long says, “Cogongrass flowers in May, and this early summer flowering time is a unique characteristic that should assist in detection.” Cogongrass invades and overtakes ecosystems, forming a dense mat of thatch and leaves that make it nearly impossible for other plants to thrive. In ecosystems that are sustained by occasional brushfires, large infestations of cogongrass may cause more frequent and intense fires, which injure or destroy native plants. Cogongrass also displaces a large variety of native plant species used by native animals as forage, host plants, and even shelter. Fortunately, cogongrass has only been found in one homeowner site in Tennessee. That site is under eradication reports Long. This weed was probably moved into the flowerbed with soil or ornamental plants from a southern state. Long recommends that homeowners be on the lookout for the invasive weed. “If you discover any cogongrass in your area, contact your county UT Extension agent as soon as possible,” she said.

Planning ahead will prevent frustration later and help save your sweet corn, beans, peas, lettuce and carrots, says a University of Tennessee extension professional. "Fencing is the most effective way to keep nuisance animals out of the garden," says Craig A. Harper, Professor of Wildlife Management at the University of Tennessee. Erecting a fence before wildlife begin feeding will help control the situation before habits form. For best results, erect your fence before or soon after planting. Small gardens do not require much fencing material, which makes this method quite efficient, especially since the materials can be used year after year. Kenneth M. Gale, www.forestryimages.org A two-strand electric fence (one strand 6 inches above ground and the other 12 inches above ground) is effective in keeping raccoons out of sweet corn and groundhogs out of leafy vegetables. A chicken-wire fence 2 feet high with the bottom tight to the ground will keep most rabbits out of vegetable patches. For deer, try a single-strand electric fence set 2½ feet aboveground with aluminum tabs attached every 3 to 5 feet. Smear peanut butter on the aluminum tabs. Deer are attracted to the peanut butter; however, when they touch their nose and/or mouth to the tabs, they quickly learn to stay away from the area. Many taste and area repellents are available for deer and rabbits. Deer Stopper® has been effective keeping deer out of gardens when applied to a "repellent fence." A cotton rope, strung around the garden approximately 2½ feet off the ground, will "hold" repellent for several days before reapplication is necessary. This method requires less repellent than spraying within the garden. "Shooting can be very effective and efficient when dealing with nuisance animals in the garden," Harper says. Shooting raccoons, groundhogs, and rabbits is legal outside designated hunting season when the animal is found depredating or about to depredate crops. A depredation permit, however, is necessary to shoot deer outside the hunting season. Requests for depredation permits should be made to the Tennessee Wildlife Resources Agency. Raccoons, groundhogs and rabbits also can be trapped using cage (live) or Conibear® (body-gripping kill) traps. Baits may include the plants that are being damaged, sardines for raccoons, fruits and melons for groundhogs, or fruits and leafy greens for rabbits. There are no toxicants registered for deer, raccoons, groundhogs or rabbits. "It is important to realize the effectiveness of these methods depends on the number of animals causing damage and the availability/quality of other food resources," Harper says. "When the offending animals are not very numerous, a patch of ladino white and red clover or cowpeas grown near the garden will lessen grazing pressure on garden vegetables by groundhogs, rabbits and deer. Regardless, using a combination of methods will be more effective than using only one method."

May 2010 5 Fruits of the Backyard Field Day Tuesday, June 15, 2010 8:30 am Middle Tennessee Research & Education Center Spring Hill, TN It may be an attempt to stay healthy; it could be a way to save money, or maybe it’s the pleasure of watching something grow. Whatever the case, the number of Tennesseans growing their own fruits and vegetables has grown tremendously in the past year. While many new growers say the experience is very rewarding, they admit that producing homegrown fresh fruits can be a little tricky. That’s why the University of Tennessee Middle Tennessee AgResearch and Education Center is once again hosting the Fruits of the Backyard Field Day. On Tuesday, June 15, UT experts will teach visitors about the production of small fruits like blueberries and grapes. The UT Extension Fruit Specialist Dr. David Lockwood will teaching sessions will include demonstrations on lead a presentation titled “Grapes, Blueberries and Other Fruit Crops – Edible Landscaping at Its Best!” at various small fruit management techniques as the June 15 Field Day in Spring Hill. Photo by G. well as proper management practices for your Rowsey. lawn and shrubs. For commercial producers, those who are looking to start their own fruit business, or those who are simply looking to get the most out of their yards, this will be an excellent opportunity to ask questions, discuss new ideas, and hear presentations from some of the region’s leading experts in fruit and lawn management.

June 2010 2 June 2010 Plant of the Month Smoketree or Smokebush Submitted by Carol Reese Truthfully, woody plants reported to have purple foliage are rarely purple. The colors are probably better described as wine, maroon, aubergine, or burgundy. Still, the word purple is just fun. It’s one of those words that sounds weirder and weirder the more you say it. The beauty and effect of purple foliage is influenced by climate, so plants that look wonderful in New England or the northwest may look tired and ugly in our southern heat. I found that to be true of the weigela ‘Wine and Roses’. I’d seen it looking glorious in northern gardens, but in our hot summer, it turned the color of tired coffee. Unfortunately the same is true of most forms of purple smoketree, also called smokebush (Cotinus coggygria). The foliage is glorious for the first few weeks of summer, but soon it fades and looks tortured by the sun. This is not true of a cultivar named ‘Grace’. ‘Grace’ is the result of a cross between Cotinus coggygria which originates from Eurasia, and Cotinus obovatus, which a small tree native to the southeastern United States. This plants does not have the rich dark purple of it’s Eurasian parent, but rather is a lovely deep mauve that flashes reddish leaf undersides. It does have large misty blooms, the feature that appears to be purple “smoke” and which gives the plant its common name. ‘Grace’ also differs in that she wants to be more like her tree parent in stature. I laughed when I saw the tag on some lately that read that the plant would reach twelve feet. I’ve seen it grow ten feet in a single season! I don’t see anything wrong with that. I think a purple tree with smokey purple flowers is a very cool addition to the landscape. Some of my gardening friends are determined to manage it as a shrub, and cut it back severely each year, which makes it throw out even more gorgeous foliage, but I like to let it go. If for no other reason, I am eager to evaluate its potential as an ornamental tree, large and fast growing enough to offer quick shade. ‘Grace’ is very easy to grow, requiring nothing more than a sunny site and well drained soils. The large misty blooms of Smoketree appear to be purple “smoke” and give the plant its common name. June 2010 3 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson July Gardening Tips If you've been working hard in your garden, July is a month during which you will reap great rewards. Perennial and annual gardens are exploding in color and vegetable gardens are offering ripe pickings. The University of Tennessee Institute of Agriculture recommends these July chores to keep your gardens and landscape in top form: Shrubs & Trees Perennials, Annuals, & Bulbs Fruits & Veggies Continue to deadhead (remove dead flowers) various annuals and perennials to encourage profuse blooming. Cut back tall, fall-flowering perennials such as iron weed, mums, and asters by one-third to one-half to reduce their ultimate height and prevent them from lodging (falling over). Watch for crabgrass and other weeds that invade your summer garden. Keep plants watered, especially container plants. July typically will be drier than any other month to date in the gardening season. Purchase and plant fall-blooming perennials such as anemone, hardy sunflowers, sedums, and toad lily. Be sure to water these plants until they become well established. Sunflowers can still be direct seeded to ensure their colorful show until frost. Prune hydrangeas after bloom. Flower buds are formed in late summer and early fall; pruning later in the year will remove next year's flowers. Prune clematis and wisteria when they are finished flowering. Harvest vegetables regularly to keep your garden productive. The bigger the squash get the fewer you will have. Plant green beans by July 10. If necessary, cover fruit trees with netting to protect the fruit from birds. Prune blackberries after harvest has ended. Remove the dying fruiting canes and tip back the vigorous, new growth two or three times to form a dense hedge for greater fruit production. Begin preparing your fall garden. Set out broccoli, cabbage, and cauliflower transplants and sow lettuce, collards, kale, and spinach seeds in late July or early August for harvest before the first freeze. Lawn Care June 2010 4 Your grass will be fine if you stop watering your lawn and let it go dormant. As cooler weather and rainfall return, it will revive. If you prefer that your lawn be green and lush through summer, mow at a higher height and water deeply. Watering in the early morning is best. What is it? Answer…Slugs Slugs are closely related to snails and differ from them by the absence of an external shell. Slugs feed on flowers, vegetables, and ornamentals, and are especially injurious to seedlings. Moreover, they get into cellars, on walks, and similar places around the house, leaving a trail of mucus or slime. Occasionally they feed on stored vegetables and other plant materials. DESCRIPTION There is a number of species of slugs; fortunately, their behavior and control is somewhat similar. The following information is applicable to most of them. Slugs are 1/4 to 10 inches long, depending on the species. Most are less than one inch long. They vary in color from cream to gray to black; some species are covered with dark spots. LIFE HISTORY Slugs have three stages in their life cycle: eggs, immature stage and adults. The young are similar in appearance to the adults except for size. Slugs may overwinter in any stage. They may survive the winter by living in protected places such as in burrows and under decaying vegetation, clods of earth, stones, boards, logs, and loose bark, to mention a few places. Slugs begin to move, hatch, feed, and lay eggs when the temperature is above 40o F. They become adults in 3 to 12 months, depending on species, food available, temperature, and humidity. Warm, damp weather in the spring and fall favor their development. Hot, dry summers are unfavorable. Although slugs are ordinarily nocturnal, they will move and feed on cloudy, damp days. During hot weather, they will be found in damp vegetation, under boards, stones, and in other cool places. CONTROL Sanitation -- Remove the resting and breeding places of slugs, such as loose boards, bricks, stones, trash piles, compost piles, weeds, and other such material. Traps -- Set out boards or burlap bags in the evening. Wet the traps and immediate surroundings. Remove trapped slugs the next morning and drop them in kerosene. Another way to trap slugs is to bury a shallow metal tray in the ground so the tray edge is level with the soil surface. Slugs are attracted to beer placed in the trays; they then fall in and drown. Natural Enemies -- Toads, some beetles and their larvae, parasitic flies, birds, chickens, and ducks are natural enemies of slugs but are not very dependable. Cultivating the soil will hasten drying of the surface and in turn will reduce slug activity.

Rains Extension Agent Bledsoe County July 2010 Plant of the Month Ornamental Mullein Submitted by Beth Willis Ornamental Mullein, the common name for a number of Verbascum hybrids, can be a charming addition to your garden. Although most are either biennials or short-lived perennials, they are remarkably lowmaintenance plants with a long season of bloom if you keep just a few things in mind while siting them. Ornamental Mullein has an upright vertical form, with tall flower spikes rising from a basal rosette of woolly gray-green leaves. Available in colors ranging from pure white to pinks, peaches, yellows and lavenders, you are sure to find one that will work in your garden. Spikes bloom from top to bottom with large, flat fivepetaled flowers. Fuzzy purple or dark pink stamens (in most varieties) add to the appeal. Blooming begins in late spring and continues through late summer or even into autumn depending on the variety. Verbascum, a member of the Figwort family, is native to Europe and Asia although some of the more than 250 species in the genus have naturalised in North America and other parts of the world. Many of the species are weedy rather than ornamental although they do have herbal uses. Native Americans used ground seed as a paralytic fish poison. Others have created medicines and dyes from the plants. Even the woolly leaves have been put to use, as the common names Poor Man’s Blanket and Cowboy Toilet Paper attest. Ornamental Mullein thrives in full sun in zones 5 to 8. It is very susceptible to root rot if drainage is not adequate, but so long as it is given good drainage it is not picky about soil type. In fact, Ornamental Mullein is well suited to the sandy or rocky soils found in rock gardens. It also works well in borders or cottage gardens with more fertile soils. It has no serious disease or pest problems and has few maintenance needs, but deadheading spent flower spikes can help prolong blooming. Ornamental Mulleins tend to be either biennials 'Jackie in Pink' is among the popular ornamental mullein cultivars in zones 5 - 8. Photo from the UT Gardens collection by B. Willis or short-lived perennials in the garden, but they can be propagated by root cuttings from late winter to early spring. In the last decade a number of ornamental hybrid cultivars have been introduced. These hybrids offer new bloom colors and color combinations, shorter plant sizes, and larger blooms. ‘Southern Charm’, a soothing blend of creamy yellows, lavenders, and peachy-pinks, grows to a height of 2 ft to 2.5 ft in the garden. ‘Caribbean Crush’ can reach heights between 2 ft and 4 ft and boasts a bright blend of tropical yellows, oranges, and lavenders on individual plants. ‘Jackie in Pink’ and ‘Jackie in Yellow’ are compact varieties (heights to 18 inches) that will even work well in containers. ‘Sixteen Candles’ and ‘Wedding Candles’, with profuse blooms of yellow and white respectively, will reach a height of 3 ft to 3.5 ft in the garden. July 2010 2 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson August Gardening Tips August is the time to reap the benefits of the hard work you have been putting into the garden since March. Gardeners everywhere should be rejoicing in how well their gardens have blossomed. One chore you can put off in August is pruning trees and shrubs, particularly hedging plants such as boxwood, hemlock and hollies. Pruning late in the season can stimulate new growth that will not harden off in time for the cold winter weather. August chores recommended to fill your lazy summer days and keep your garden and landscape in top condition: Control crabgrass and other weeds that have invaded your lawn and garden. Weeds will be an even bigger problem next year if you let them go to seed. If you want to use chemical control, be sure to select the appropriate herbicide for the location and follow label instructions. August is a great time to plant perennials in pots to add late-season color to your garden. Remember to keep tall flowers staked. Be sure to keep garden mums well fertilized until buds show color. Check water needs daily. During the hot days of August, hanging baskets and containers tend to dry out daily. The fallen leaves below your roses and peonies need to be cleaned out to avoid diseases and insect invasion during the winter months. Pick summer vegetables every day or two to keep the plants producing. Take plenty of photos of your garden so next year you can refer back to them to see which plants you liked or disliked. Hummingbirds migrate in August so keep feeders full. Also, change the water in bird baths regularly. Standing water is less healthy for the birds, and it may become a breeding ground for mosquito larvae. Fertilize azaleas, pieris, mountain laurel and other ericaceous (acid-loving) species before the end of August. Use an acid-based soluble fertilizer containing iron. Also fertilize roses to encourage last new growth and hardening off before frost. Fertilize tall fescue and Bermuda lawns in late August using a high nitrogen fertilizer of a 5:1:1 ratio. If the lawn needs extensive renovation and aeration, however, wait until early September. Early September is the month to start fertilizing fescue and other cool season lawns, if you have not taken a soil test recently now might just be the time to do so. Spray the underside of leaves with an appropriate insecticide, insecticidal soap or a summer oil to control sap-feeding lacebugs. Dig potatoes after the tops have died down. Sow seeds for late crops of beets, bush beans, cabbage, carrots, collards, kale, lettuce, peas, spinach, turnips, kohlrabi and onions until August 15th. Transplants can still be planted of broccoli, early cabbage, cauliflower, collards, kale and onions as well. As Japanese beetles return to the soil late in the month, treat for grubs with milky spore disease or beneficial nematodes. This will reduce winter mole destruction on your lawn. Mow the lawn on a high setting if the weather is dry. Keep everything well watered. July 2010 3 Avoiding Heat-Related Problems Adapted from Carol A. Rice, Ph.D., R.N., Professor and Extension Specialist, Texas AgriLife Extension Service, Texas A&M System. Types of Heat-Related Problems Heat Cramps – symptoms include painful cramping and spasms of legs, arms and/or abdominal (stomach) muscles. Heat Exhaustion – symptoms include feeling tired, weak, and dizzy; headache, nausea and possible vomiting. Heavy perspiration; skin feels moist. Heat Stroke – symptoms include feeling tired, weak and dizzy. Skin feels hot and dry, even under armpits; appears red and flushed. May become delirious and unconscious. This is a life threatening situation! Call 911. Reducing Your Risks 1. Drink lots of cool water Drink lots of cool water, even more than you think you need, when the weather is hot and humid. (High humidity makes heat injuries more likely because perspiration does not evaporate from the skin as quickly; this causes the body to cool down more slowly.) Water is best; fruit and vegetable juices are good, too. Drink at least a gallon of liquid a day (about 16 glasses) when the outside temperature is above 90 degrees and you are not in airconditioned surroundings. This will mean drinking 1 1/2 times as much liquid as your thirst signals you to drink. Overweight people need even more water during summer than average weight people. Do not drink beer or other alcoholic beverages, coffee, tea or other drinks containing caffeine because they cause you to lose fluid. heart disease or high blood pressure, ask your doctor about your salt intake. 3. Wear light-colored clothes Wear light-colored clothes that are loosely woven and absorbent. Cotton is best; it absorbs 40 percent of its weight in moisture. Most synthetic (manmade) materials trap body heat and are not absorbent. Wear a hat to shade your head. 4. Avoid outside activities during the heat of the day If you are required to work outside, take frequent breaks and drinks of cool water. Do not run or do other types of energetic exercise during the heat of the day. Get wet, wear wet clothing, or bathe/shower as often as possible without drying yourself—this gives your body cooling system a boost. 5. If there is no air conditioning: Use a fan. Open windows wide to create as much cross ventilation as possible. If your apartment or home is shaded from the sun at certain times of the day, the windows should be open on that side, and the drapes/shades should be closed on the sunny side of your home or apartment. Avoid cooking. Go to a cool place, if possible, like the library, the senior center, the theater, or the shopping center during the heat of the day. Take frequent, cool baths or showers. 6. Older people are more sensitive to heat Realize that older people are more sensitive to heat and may easily suffer heat-related sickness. Also, anyone with diabetes, heart disease, arteriosclerosis, high blood pressure, or Parkinson’s Disease is more sensitive to the effects of heat. 2. Maintain normal salt intake Maintain normal salt intake in your diet (1 1/2 teaspoons or less per day).

You have to wash your hair to get your fingernails clean. All your neighbors come and ask you questions. You know the temperature of your compost every day. You buy a bigger truck so that you can haul more mulch. You enjoy crushing Japanese beetles because you like the sound that it makes. Your boss makes “taking care of the office plants” an official part of your job description. Everything you touch turns to “fertilizer”. Your non-gardening spouse becomes conversant in botanical names. You find yourself feeling leaves, flowers and trunks of trees wherever you go, even at funerals. You dumpster-dive for discarded bulbs after commercial landscapers remove them to plant annuals. You plan vacation trips around the locations of botanical gardens, arboreta, historic gardens, etc. You sneak home a 7 foot Japanese Maple and wonder if your spouse will notice. When considering your budget, plants are more important than groceries. You always carry a shovel, bottled water and a plastic bag in your trunk as emergency tools. You appreciate your Master Gardener badge more than your jewelry. You talk “dirt” at baseball practice. You spend more time chopping your kitchen greens for the compost pile than for cooking. You like the smell of horse manure better than Estee Lauder. You rejoice in rain…even after 10 straight days of it. You have pride in how bad your hands look. You have a decorative compost container on your kitchen counter. You can give away plants easily, but compost is another thing. Soil test results actually mean something. You understand what IPM means and are happy about it. You’d rather go to a nursery to shop than a clothes store. You know that Sevin is not a number. You take every single person who enters your house on a “garden tour”. You look at your child’s sandbox and see a raised bed. You ask for tools for Christmas, Mother/Father’s day, your Birthday and any other occasion you can think of. You can’t bear to thin seedlings and throw them away. You scold total strangers who don’t take care of their potted plants. You know how many bags of fertilizer/potting soil/mulch your car will hold. You drive around the neighborhood hoping to score extra bags of leaves for your compost pile. Your preferred reading matter is seed catalogs. And last but not least: 37. You know that the four seasons are: (a) Planning the Garden, (b) Preparing the Garden (c) Gardening and (d) Preparing and Planning for the next Garden. -Author Unknown From the Master Gardeners of Rutherford County Newsletter “The Scoop” July 2010 http://mastergardeners-rc.org/assets/applets/Newsletter201007.pdf July 2010 5 Bledsoe County Nursing Home Project Several days (or more) worth of work has gone into this project to build planters for residents to enjoy.

Rains Extension Agent Bledsoe County August 2010 Plant of the Month Lenten Rose Are you thinking about the 2011 garden season and are asking, “What plant has interest that I can enjoy throughout all the seasons?” Lenten Rose, or Helleborus x hybridus, may be the answer. Lenten Rose is a durable perennial that performs well in shade gardens, has evergreen foliage and produces colorful blooms in early spring. Lenten Rose has recently been named the 2005 Perennial Plant of the Year by the Perennial Plant Association, a national organization dedicated to the promotion of perennial plants. There are several reasons to include this plant in your garden. In late winter to early spring, Lenten Rose starts to bloom and will continue to do so for up to three months. Bloom colors range from white and light pink to red and deep purple. There are single- and double-flowering forms and bicolor blooms, too. After flowering, enjoy the clean, dark green foliage that makes this plant a must-have in any shade garden. Clumps are generally 2 feet wide by 2 feet tall, and the foliage adds a unique bold texture to the shaded landscape. For this, Lenten Rose makes a perfect backdrop for the delicate blooms of spring-flowering bulbs and other perennials, such as Bleeding Heart (Dicentra spectabilis). If the foliage gets tattered and rough-looking in late winter, simply cut it back as the new leaves emerge. Doing this prior to blooming also improves the display of the blooms. This easy-to-grow plant prefers a rich, welldrained soil. It should be planted in a partial shade to full shade location. Once established, Lenten Rose is a tough, drought tolerant perennial. Lenten Rose also requires very little care. Unlike many other garden perennials, Lenten Rose does not typically require dividing every 35 years. According to the Perennial Plant Association, established clumps of Lenten Rose can be left alone for up to 20 years. If your Lenten Rose needs dividing, keep in mind that it will take the divisions a little time to recover. This plant recovers from dividing slower than most, so it will appreciate a little patience and tender care. Lenten Rose is a great shade perennial to pair with other plant textures and colors like ferns and impatiens. This plant is also a good companion to other early spring bloomers, such as Barrenwort (Epimedium sp.). Lenten Rose is used quite nicely as either a specimen plant or in mass in a shade garden. Allow this plant to naturalize in a woodland setting. Because flowers can hang just below the foliage, consider planting Lenten Rose on a slope or hillside to enjoy viewing the flowers from another angle. For those whose gardens are typically buffets for deer, good news! Lenten Rose is a deer-resistant perennial! Plant Lenten Rose in your garden now and enjoy its evergreen foliage all year. When it gets to be late winter next year, and there seems to be nothing to enjoy out in your garden, your Lenten Rose will signal that it’s time to look forward to spring. The delicate flowers of Lenten Rose make a perfect backdrop for spring-flowering bulbs and other perennials. Photo taken by Hugh Conlon, UT Extension Area Ornamental Horticulture Specialist. August 2010 2 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson September Gardening Tips Children are back in school. The weather is beginning to change, and the calendar says it is time to wind up the summer growing season and prepare your fall garden. Experts from the University of Tennessee Institute of Agriculture recommend performing the following chores as you prepare for autumn: Create and work on your landscape plan for fall planting of trees and shrubs. Assess areas within your garden beds that need planting. Purchase spring-flowering bulbs for fall planting. Divide and transplant perennials in your garden beds. If you have more plants than you need, share a few with your neighbor. If frost threatens, bring tender plants inside for the winter. Be sure to inspect for insect pests! Dig up tender bulbs, such as caladium and dahlia, and store them in a cool, dry location. Plant late-season annuals including ornamental kale and cabbage, giant red mustard, pansies, violas and chrysanthemums. Keep planting cool season veggies, such as Swiss chard, parsley, broccoli, cabbage, lettuce and radish. Continue to harvest veggies and herbs. Consider harvesting flowers such as Gomphrena, Celosia,and yarrow for fresh and/or dried flower arrangements. Collect seed from this year's annuals and perennials for next year's garden. Fertilize roses one last time. Prune dead or diseased canes. Prune rambling roses. De-thatch and aerate existing lawns. This helps to stimulate and promote root growth. Take photos of and write notes about this year's garden. How did your garden perform? What plants or techniques worked? What didn't? What would you like to do in your garden in the future? These notes and pictures will help you when preparing your garden next season. Start filling up bird feeders for our finefeathered friends. Blossom-end Rot With the hot dry weather blossom-end rot can become a problem in tomatoes, peppers, and watermelons. Low levels of calcium and low soil moisture are causes of this problem. August 2010 3 Emerald Ash Borer Discovered in East Tennessee - Plans underway to survey and restrict movement of ash material in Knox, Loudon counties (the following is a Tennessee Department news release) Emerald Ash Borer David Cappaert, Michigan State University, Bugwood.org Nashville, Tenn. – The Tennessee Department of Agriculture today announced the discovery of emerald ash borer (EAB), the first detection of the destructive tree pest in the state. The discovery was made last week at a truck stop in Knox County near the Loudon County line. “We knew EAB could potentially reach Tennessee, and we’re prepared to help slow the spread of the infestation and protect our forest resources.” said state Agriculture Commissioner Ken Givens. “We will be working closely with federal officials and other stakeholders to determine the extent of the infestation and to take steps to limit its spread.” After receiving a report of a suspected find, state and federal officials collected specimens from infested logs for submission to the U.S. Department of Agriculture for positive identification. USDA confirmed the find late last week. EAB attacks only ash trees. It is believed to have been introduced into the Detroit, Mich. area 15 to 20 years ago on wood packing material from Asia. Since then, the destructive insect has been found also in Illinois, Indiana, Iowa, Kentucky, Maryland, Minnesota, Missouri, New York, Ohio, Pennsylvania, Virginia, West Virginia and Wisconsin. In response to the find, TDA plans to issue a quarantine in Knox and Loudon counties prohibiting the movement of firewood, ash nursery stock, ash timber and other material that can spread EAB. TDA plant inspectors and foresters will conduct a thorough survey of trees in the areas to assess the extent of the infestation. The USDA Animal and Plant Health Inspection Service is working closely with TDA in response and will likely issue a federal quarantine in the coming days in support of national efforts to control the spread of EAB. Typically, the Emerald Ash Borer beetles can kill an ash tree within three years of the initial infestation. Adults are dark green, one-half inch in length and one-eighth inch wide, and fly only from April until September, depending on the climate of the area. In Tennessee, most EAB adults would fly in May and June. Larvae spend the rest of the year beneath the bark of ash trees. When they emerge as adults, they leave Dshaped holes in the bark about one-eighth inch wide. The Tennessee Department of Agriculture Division of Forestry estimates that 10 million urban ash trees in Tennessee are potentially at risk from EAB. The risk represents an estimated value loss of $2 billion. There are an estimated 261 million ash trees on Tennessee public and private timberland potentially valued as high as $9 billion. TDA officials urge area residents and visitors to help prevent the spread of EAB: Don’t transport firewood, even within Tennessee. Don’t bring firewood along for camping trips. Buy the wood you need from a local source. Don’t bring wood home with you. Don’t buy or move firewood from outside the state. If someone comes to your door selling firewood, ask them about the source, and don’t buy wood from outside the state. Watch for signs of infestation in your ash trees. If you suspect your ash tree could be infested with EAB, visit www.TN.gov/agriculture/eab for an online symptoms checklist and report form or call TDA’s Regulatory Services Division at 1-800-628-2631.

Thousand Cankers Disease found in Tennessee NASHVILLE – The Tennessee Department of Agriculture today announced the discovery of Thousand Cankers Disease (TCD), the first detection of the destructive tree pest east of the Mississippi River. The discovery was made in July by a TDA forester. J. C. Rains Extension Agent Bledsoe Co. PO Box 289 Pikeville, TN 37367 423-447-2451 IN THIS ISSUE Dates to Remember UT Garden’s Plant of the Month Garden tips ___________________ A black walnut tree branch infected with Thousand Cankers Disease. “The discovery of TCD in Tennessee is unexpected, but we’re prepared to help slow the spread of the infestation and protect our forest resources.” said State Agriculture Commissioner Ken Givens. “We will be working closely with stakeholders to determine the extent of the infestation and to take steps to limit its spread.” (continued page 2) TN.gov Newsroom The onion is a lily, botanically. Asparagus is also a member of the lily family. The name "asparagus" comes from a Greek word meaning "sprout". J. C. Rains Sheldon D. Barker Extension Agent Sequatchie County J. C. Rains Extension Agent Bledsoe County TCD is a progressive disease that kills a tree within two to three years after initial infection. The disease-causing fungus, Geosmithia, is transmitted by a small twig beetle. Branches and trunk tissue are killed by repeated infections by the fungus, as the beetles carry the fungus into new bark. The TCD discovery comes a week after emerald ash borer (EAB) was found. Both TCD and EAB have the potential to cause significant damage to Tennessee forests. It is imperative that citizens work to prevent the spread of both. In response to the find, TDA plans to issue a quarantine in Knox county prohibiting the movement of firewood and black walnut nursery stock and limiting the movement of black walnut timber and other material that can spread TCD. TDA plant inspectors and foresters will conduct a thorough survey of trees in the areas to assess the extent of the infestation and to see if more quarantines are warranted. The Tennessee Department of Agriculture Division of Forestry estimates that 1.38 million black walnut trees in Tennessee’s urban areas are potentially at risk from TCD. The risk represents an estimated value loss of $1.37 billion. There are an estimated 26 million black walnut trees on Tennessee public and private timberland potentially valued as high as 1.47 billion dollars. TDA officials urge area residents and visitors to help prevent the spread of TCD and EAB: Don’t transport firewood, even within Tennessee. Don’t bring firewood along for camping trips. Buy the wood you need from a local source. Don’t bring wood home with you. Don’t buy or move firewood from outside the state. If someone comes to your door selling firewood, ask them about the source, and don’t buy wood from outside the state. Watch for signs of infestation in your black walnut trees.

New growth maintains its copper to burgundy colored stems, which contrast nicely with the pink starshaped flowers. If you are looking for a great plant of interest for the transition from summer to fall you may want to consider Glossy Abelia. In fact, this multi-stemmed woody shrub has attributes that make it a desirable addition to the landscape year round. This old fashioned shrub often has long arching canes that provide a graceful profile that is filled with fragrant soft pink blooms. It can start blooming as early as late May but continues to bloom all summer into mid fall, including September, when summer annuals are fading before fall foliage appears. Glossy Abelia, or Abelia x grandiflora, gets its name from the shiny leaves of the shrub. In the Southeast these leaves are semi-evergreen and remain on the plant all year. There are several cultivars available that offer a variety of leaf color and growth habit. ‘Canyon Creek’ is a nice rounded shrub with dense foliage. New growth is copper colored, but it then turns to yellow and finally green. The plant often maintains its copper to burgundy colored stems, which contrast nicely with the pink star-shaped flowers. ‘Kaleidoscope’ is a wonderful introduction that has a more tubular flower and blooms in clusters. Its foliage has a slightly golden variegation on bronze stems that again contrasts with the blush pink blooms. Once the blooming stops the flower’s copper colored sepals remain and continue to provide showy color. With all these subtle colors on one plant it is no wonder this plant has kaleidoscope as its name. Both of these cultivars tend towards a copper bronze color in fall and don’t lose many of their leaves. Glossy Abelia is very easy to grow in the South. It requires full sun but will tolerate partial shade. It is also not terribly temperamental when it comes to soil, adapting to a wide variety of conditions. Once established it is reasonably drought resistant too, although some leaf drop and fewer blooms may occur with extended periods of drought. Pruning does not usually become an issue if given enough room to grow in the first place. Typical shrubs grow to about 5-6’ with smaller dwarf cultivars reaching 3-4’. There is even a prostrate form that grows 1-2’ with a spreading ground hugging habit. The graceful arching canes are one of this shrub’s attributes which along with the small leaves give it a fine texture in the garden. Selectively pruning older canes will encourage new growth but maintain the shape and texture. There are few shrubs that offer year round interest, but Glossy Abelia is one that comes close. September 2010 3 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson October Gardening Tips October is typically Tennessee’s driest month, so be sure your garden doesn’t get too dry. Here are some fall gardening tips from the University of Tennessee Institute of Agriculture: Perennials, annuals, and bulbs Weed your garden one last time. Eliminating weeds now may prevent problems next spring. Plant spring-flowering bulbs in late October and early November. Collect wildflower seeds. Sow them now or early next spring. Plant winter annuals for a show of color until spring. Great plants to try include pansies, violas and snapdragons. Winter-hardy herbs like parsley, thyme and rosemary make good container companions with winter annuals. Cut back withering perennial blooms and add fresh mulch. Follow mulching with a preemergent herbicide to prevent winter weeds. Plant mums now. Keep your grounds raked clean of leaves and debris. Add fallen leaves, old plant parts and grass clippings to the compost pile. Lawn Care Renew your tall fescue lawn. Nitrogencontaining fertilizers can speed grass growth, thicken the lawn and improve its color. Seed and mulch bare areas to control erosion and reduce weed problems. Core aerify your lawn to help water and nutrients move into hardsoils. If your lawn is thin and you intend to seed, a power rake can lift thatch and expose soil before planting. It is best to seed lawns by mid October, but fertilizer can be applied as late as mid December. Fruits and veggies Harvest pumpkins, summer squashes, and gourds before the first frost. Pumpkins that are showing color will continue to ripen after harvest. Dig and divide congested clumps of rhubarb. Plant apple trees now. Select disease-resistant varieties. Keep harvesting cool-season vegetables. Frost actually enhances the flavor of parsnips, Brussels sprouts and kale. Plant individual cloves of garlic for a crop next summer. Select very large cloves to produce the largest bulbs. Plant them 6 inches deep and at least 6 inches apart. Mulch them after the ground freezes for winter protection. Mulch root crops such as carrots, onions, and parsnips to keep the ground around them from freezing. They can be dug up as needed during winter. Clean around fruit trees. If diseases or insects wiped out your fruit crop this year, destroy fallen fruit and remove fruit that has mummified on the tree. They will cause an early attack next year. Consider using a home fruit spray schedule available from your county Agricultural Extension office. Plant a cover crop of clovers, cow peas, soybeans, or vetches over your summer garden. Plan to plow it under next spring. These nitrogen-producing plants provide good organic matter and food for next year’s garden as well as help to control weeds over the winter. Odds and Ends Plant trees and shrubs. Be sure to water well until rainfall picks up in November and December. Decorate your garden for fall. Displays can also add a festive touch to a front porch, landscape or strategic places like a light post or the driveway entrance. September 2010 4 Store amaryllis in a cool spot (40 to 50 degrees) for a two-month rest. Begin watering again 9 to 12 weeks before you want it to flower. Place Thanksgiving and Christmas cactus in an east or north window. Fertilize them once more. Let them dry out more between waterings to help stimulate blossoms. Start a compost pile. Fall is the ideal time to start composting. Use materials such as fallen leaves and gleanings from vegetable and flower gardens. Your county Agricultural Extension office has information on how to compost. Provide migrating birds food for their journey. You might persuade a few to stick around if they know they have a reliable food source. Hours Don’t forget that the year is three-quarters gone. If you have hours please record them on-line or see that they get turned in. I have to send or reference on-line entries for the 100 hours. So please turn in or enter your hours!

Resourced from the USDA – APHIS.GOV WEBSITE http://www.aphis.usda.gov/newsroom/hot_issues/firewood/index.shtml Whether used to heat your home or build a campfire, firewood is a musthave item for millions of Americans. However, firewood also presents a very real threat to the Nation’s forests. Invasive species including the Asian longhorned beetle (ALB) and emerald ash borer (EAB) can be spread into new areas of the country on firewood. To date, ALB and EAB have been detected in a total of 13 States and without intervention the continued spread of these pests is likely. To this end, APHIS is combating these invasive pests with quarantines, public awareness campaigns and other efforts in known infested areas, while some States have adopted regulations limiting the movement of firewood. However, these actions alone are not enough; it is up to all of us to contribute to the preservation of our Nation’s forests by committing to not move firewood from where it is cut. By “burning where you buy it” you can be sure that you’re not accidentally moving these damaging forest pests into new areas. Bringing firewood from home to the place your camping could put your favorite campsite or park in danger. Thousands of campgrounds are scattered throughout the United States and camping is a popular recreational activity for millions of people each year. Campfires are an integral part of camping, and campers often bring their own firewood due to the cost and quality of firewood provided at or near campgrounds. Some campers have been known to bring firewood from one side of the country to another. Firewood is often made from diseased or insect-ridden or killed trees, and curing or drying times for firewood can be as little as three months. People camp more often during the summer and early fall months, and insects or other pests are most active during these seasons. Movement of firewood by campers is often September 2010 5 limited to 100 or 200 miles, presenting a substantial risk for exacerbating the spread of pests locally. Because some campers move firewood long distances, this is a greater risk for new long distance spread infestations. As an example of a specific camping-related activity, stockcar racing is a popular spectator sport for millions of people in the United States. Races take place from February through November at venues scattered throughout the country and many fans camp while traveling the circuit. In 2006, after an employee at Great Smoky Mountains National Park noticed a visitor with firewood coming from an EAB-quarantined area. USDA-APHIS Plant Protection and Quarantine (PPQ) Agency conducted a firewood survey in eastern Tennessee, including Sullivan County, where the Bristol Motor Speedway is located. Campgrounds near the speedway hosted campers from 40 different states; campers from 14 states had transported firewood to the race. Four seizures were made in violation of EAB quarantines, approximating 120 pieces of firewood (Pentico, 2006). The hardwood firewood seizures came from Michigan, Indiana, and the Canadian province of Ontario, localities over 500 miles from the campgrounds. Additionally, most of the out of state visitors with firewood came from Florida, North Carolina, Georgia, and other southern states. This is noteworthy because the redbay ambrosia beetle, Xyleborus glabratus, is associated with a fungal pathogen, Raffaelea lauricola, which causes laurel wilt disease (LWD) and kills trees in the Lauraceae family, including redbay, sassafrass, and others. These tree species occur in LWD-infected areas and are often utilized as firewood. Similar blitzes were conducted in the Bristol, TN, area in 2007 and 2008. In 2008, a total of 29 firewood seizures occurred. Of these seizures, 75% of the people moving firewood knew about the quarantines, but moved the wood out of the quarantined areas anyway. Conversely, people who made reservations at campgrounds that expressly directed people not to bring firewood with them did not bring firewood, thus demonstrating the potential efficacy of citizen outreach programs. Much work has been done to raise awareness of the issues surrounding the movement of firewood by campers, and it does appear that people are becoming aware of the associated risks and that some are altering their habits. Many campgrounds and state forestry agencies are adding their assistance and urging visitors to parks and campgrounds to leave firewood at home and purchase it locally. When you bring firewood camping, you risk carrying a tree killing insect or disease. The bugs can crawl out, spread to the trees and forest at the campground or state or national park, and begin to destroy those trees and forests. That means less fun for future campers. We are all careful to extinguish campfires, pick up after ourselves in campgrounds, state parks and national parks, so we should be conscientious campers when it comes to moving firewood as well. What can you do to stop the spread of invasive pests on firewood? Never take firewood with you – always buy it near where you will burn it. Tell your friends and family members not to move firewood. Firewood you buy should be from only a few miles away, or at least in the same county of the park you are staying.

J. C. Rains Sheldon D. Barker Extension Agent Sequatchie County J. C. Rains Extension Agent Bledsoe County Fire ants and Honey In a past issue (January 2010) we mentioned several “home remedies” that are recommended for Fire Ant Control. A recent twitter stream has suggested using boric acid mixed with honey to attract and kill the ants. While this may actually work, UT Entomologist warn that this method used outside would be illegal in many states, but more importantly unethical. Honeybees will readily collect spilled honey. Once one honeybee collects it, it will recruit others to this rich source of 'nectar'. The pesticides will then impact or kill the hives. Many states make knowingly baiting syrups with pesticides to kill honeybees illegal (Tennessee is one of the states), since this has been a problem. The Law in Tennessee reads in part: “Prohibited: (2) Placing in a location that is accessible to free-flying honeybees any honey, sugar syrup, corn syrup, or other substance known to be attractive to bees and to which some pesticide or other substance harmful to honeybees has been added.” The full text can be found at http://acbeekeepers.org/ (click "TN Apiary Law", left column). Pruning 101 With cold months, it is time to think about pruning, a task that may not be as daunting as many think. First, you need to know why you are going to prune: that answers a lot of the when and how questions. You may be pruning to remove damaged, diseased, or dead tissue from your trees or shrubs. This can be done at almost any time. The one exception would be when you are removing a fungal disease. In that case, do not prune when the fungus is producing spores as that could infect your new cuts. Otherwise, remove dead or dying branches when you find them. Also, if all you want to do is remove a stray branch, you can do that at any time. Other than removing damaged tissue or removing that one unsightly branch, never prune in the spring or fall when the sap is flowing. Summer or winter may be best, depending on the type of plant. Cutting just the end of a branch that is over 3 inches in diameter will cause a dense growth of sprouts that will cut off light to the inner part of the tree. Go back to a fork and make your cut just past the collar (thick area at the base of the branch where it attaches to the trunk or another branch). This will leave less cut area exposed and allow the cambium layer to grow over the wound. For branches less than 3 inches in diameter, cut just outside a bud pointed in the direction you want the branch to continue growing. Slant the cut slightly upward to prevent water from soaking into the wound. Use hand pruners, long handled loppers or a pruning saw, depending on the size of the branch. The next thing to decide is what kind of plant you are pruning. For flowering or fruiting shrubs or trees, do not cut off branches until after they have flowered or set fruit. So for spring flowering shrubs, you would do the pruning in the early summer as soon as the flowers have faded. The new growth that comes after pruning will bear flowers next spring. For summer flowering or fruiting shrubs, wait until late winter or very early spring before the sap starts running. Late fall is generally a bad time to prune any tree or shrub because pruning tends to promote new growth. Pruned plants will not have enough time to “harden” to prevent freeze damage. In general, whether you want to prune to control size or improve light and air penetration, you will want to select carefully those branches to remove so that you do not create a hedge (unless that is what you want!). From “Pruning 101” By Barbara M. Tobias Polk County Master Gardeners News Articles http://www.uaex.edu/polk/MG/Articles/pruning_101.htm October 2010 2 They’re Back! Don’t Let the Bed Bugs Bite “Good night. Sleep tight. And don’t let the bed bugs bite.” What many of us grew up thinking was a funny goodnight wish is once again a genuine expression of well being. Little did we know that there ARE bed bugs and they DO bite. A generation of people have never seen bed bugs and didn’t realize that they really exist. They are back in a big way, and they are beating out Lindsay Lohan for media attention. They’ve now been found in hotels, hospitals and homes in Tennessee, and America’s city, New York, has what many are calling a major infestation. Here are some resources to help you understand bed bugs, how to prevent them and what to do if your home becomes their next abode. Bed Bugs Making a Comeback in Tennessee, Too!

October 2010 3 October 2010 Plant of the Month Virginia sweetspire Now that autumn has arrived, we are all anticipating the brilliant fall colors that the season provides. For the most part when we think of fall foliage what comes to mind are trees. We anticipate the beautiful maples, dogwoods, and ginkgos with their bright orange, red, and yellow leaves. But don’t forget about shrubs and the wonderful colors they can provide in the understory or around the foundation of your home. One of the showiest of these shrubs is a native shrub called Virginia sweetspire (Itea virginica). Sweetspire is a great shrub choice because it features both summer blossoms and fall color. Beautiful fragrant creamy white flower clusters (4 inches to 6 inches long) often droop and cover the shrub with graceful blossoms in the summer and make the shrub very attractive to butterflies and bees. Yet, it is deer resistant. This shrub can be grown in partial shade to full sun and can tolerate a variety of soils including our clay soils. It does need adequate moisture when first planted (in fact, it will grow well in boggy areas), but once established it is very low maintenance. This multi-stemmed shrub suckers and spreads outward forming colonies. This habit makes it ideal for erosion control. So do not plant sweetspire in a confined space. You will want to give it room to grow. Virginia sweetspire’s beautiful blossoms are outshined by its fall foliage. The shrub turns the most beautiful red-orange to crimson color in the fall and retains its leaves well into November, making it ideal for the fall landscape. One cultivar readily available is ‘Henry’s Garnet’. Growing to about 6 feet tall, this cultivar has rich crimson fall foliage and typically holds its leaves longer than the straight species. For a compact variety that’s more suitable to the smaller landscape choose ‘Little Henry’; this cultivar tops out at about 3 feet tall. This newer cultivar has much going for it. Its short growth habit makes ideal for mass planting, on a bank for example, or by itself as a specimen in the mixed border. It is even suitable for container gardening, adding a dramatic focal point in the center or back of the container. Its flower spikes are more upright and stay well above the foliage and its foliage turns spectacular oranges and reds in autumn, again retaining its leaves well into late fall. Virginia sweetspire is a wonderful lowmaintenance, native shrub that can tolerate a wide range of conditions. Add to that its fragrant, showy blooms and its stunning fall color and you have a great plant for any landscape. Henry's Garnet’ is among the readily available cultivars of the native shrub Virginia sweetspire. Its deep red fall foliage makes the shrub a standout in the autumn landscape. Photo by C. Reese. October 2010 4 “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson November Gardening Tips November Gardening Tips November! This can only mean that winter is around the corner, and outdoor activities will be winding down. But there are things you need to think about during the winter months to keep your lawn and garden in order. Shrubs and trees Plant or transplant trees, shrubs and fruit crops now. Be sure to mulch newly planted plants using three to four inches of mulch. Prune back late-season-blooming trees and shrubs. Fire blight was a problem for some this spring and now is the time to prune dead limbs not already removed. Also clean the orchard and vineyard of fruit. Mummified fruit on the tree or vine may indicate disease. Remove the fruit still hanging and rake and clean around the plant. Fertilize trees and shrubs before the ground freezes to make food available to plants in early spring. Protect roses for the winter. Perennials, annuals, and bulbs Plant spring-flowering bulbs now. Cut chrysanthemum stems and other perennials to four to five inches from the soil once they have begun to die back. Continue to transplant perennials throughout the fall and winter, as long as they remain dormant. Add three to four inches of good compost or fine mulch to flower beds to keep soil temperature stable and to prevent winter plant injury from frost heaving. As compost or fine mulches decompose, they will enrich your garden soil. Lawn care Rake and remove heavy layers of leaves from the lawn. Alternatively, you can mow over a light layer of leaves, turning them into a mulch that will replace important nutrients in your lawn. If you compost make sure you mix the leaves with other materials. Grass clipping for example. A mix of 2-3:1 (leaves:grass clippings) is generally considered optimum for decomposition in the compost pile. Indoor plants Give houseplants as much light as possible during winter's lower-light days. Continue to let up on fertilizing indoor plants until spring. If possible, provide houseplants with increased humidity as levels. Indoor heat can be too dry. Begin to increase the time between waterings but do not cut back on the amount of water. Force bulbs like narcissus, hyacinths and amaryllis indoors for color early in the new year. Start paperwhites in late November for Christmas flowering.

December 2010 Plant of the Month Eastern Red Cedar, Juniperus virginiana Submitted by Andy Pulte Those who spend their time outdoors or gardening understand that a plant can grow on you over time. Sometimes a plant you’ve overlooked can start to gain your interest. Often this is a plant that you look at for a second time as a possible addition to your landscape or garden. Other times natural curiosity leads you to learn more about a particular species. Juniperus virginiana or Eastern red cedar is one such plant. It is so very common that many of us have never taken the time to learn about some of the things that make it special. Eastern red cedar is native to 37 U.S. states as far west and north as North Dakota, south to the Great Plains of Texas and eastward. Actually, under cultivation, this plant will grow in pockets of all 50 states. When I drive the roads of many of these states I often look out my window and marvel at the infinite numbers of shapes and forms of Eastern red cedar that are found along the roadside. I remember a friend of mine remarking that they were a lot like people, fat ones, skinny ones, tall ones and even some short ones. This polymorphism contributes to Eastern red cedar not being a traditionally good nursery plant. Often pyramidal in youth, most plants open up to a broader, unpredictable crown with age. Eastern red cedar was a plant that I distinctly remember from a very early age growing up in Nebraska. Miles and miles of cornfields were broken up by scattered farmhouses surrounded by windbreaks of Juniperus virginiana, many of which were planted in the hard times of the 1930’s. As the only native coniferous tree available in many areas, the red cedar was also an early traditional Christmas tree species. I remember as a child walking through thickets of Eastern Red Cedar and not particularly liking the smell or the feel of this plant that seemed to be everywhere. I have seen pastures left ungrazed or unburned consumed by this early land invader. In fact, Eastern red cedar has been shown to be at least slightly allopathic in nature, reducing or slowing the growth of some prairie plants. Eastern red cedar may exhibit a variety of forms from tall and narrow to short and rounded. Photo by A. Pulte. Bottom line: Eastern red cedar was made to survive. It can be grown from USDA Hardiness Zones 2 through 9, is long lived, grows in some of the windiest conditions imaginable, has minimal pest problems, will grow in almost any soil, and can even withstand salt spray when grown near a beach. Now, this isn’t a perfect plant. Deer will browse red cedars as high as they can reach, bagworms sometimes make their home in them, and it is the alternative host for cedar-apple rust disease, which can be devastating to susceptible apple cultivars and plants such as hawthorns. However, rust resistant cultivars of apples and hawthorns are available. When faced with large wild populations of Eastern red cedar these are the best choice. Additionally, pollen can be of concern for sensitive allergy sufferers. December 2010 2 Continued on next page For many years, few cultivars of this plant were very commercially available. Several of the early selections were plants that stayed rather short or had grayish foliage. Many people know the cultivar ‘Grey Owl’ which has been around since the thirties. If you do a little plant hunting in the wild, it is fairly easy to find both columnar and more robustly round plants growing in populations within a few feet of each other. But form is not the only thing to consider with Eastern red cedar. Winter brings a change to this plant. Depending on the individual plant, cool temperatures can help change the foliage color to a deep purple or even copper in color. This change can be looked at as either adding character or as a disadvantage. Many nurserymen have made selections of this plant based on form combined with a lack of this color shift, looking for a plant that remains consistently deep green throughout the winter. In the wild you will find Eastern red cedar growing as tall as 100 feet; however, in cultivation it would be rare to see a plant that high. Different populations of trees will also have a variety of looks. Northern populations often will be very narrow, Southern populations tend to be slightly more broadly tapered (although there are exceptions). As you travel to the wind-swept Great Plains, you see a shrubbier look with older trees becoming outstanding specimens resembling giant bonsais. One of my favorite cultivars of this plant is Juniperus virginiana 'Taylor'. ‘Taylor’ was found as a sport (part of a plant that shows morphological differences from the rest of the plant) in Taylor, Nebraska, and was released by the Nebraska Statewide Arboretum. It will reach nearly 30’ high but will remain just over 3 feet in width. This makes it a plant that could be great for screens or as a columnar accent in a garden. Other cultivars available include some that are powder blue in color or have variegation in their foliage. 'Elegantissima', which is slightly pendulous, has golden-tipped branches and a bronzy fall color. Historically, Eastern red cedar has a variety of commercial uses. The first one that often comes to mind is the use of the wood to line closets and make furniture. However, it’s important not to overlook the role it played in the development of many parts of this country as one of the most durable and rot-resistant fence posts available to early settlers. Additionally, many of the greatest minds in this country have been educated while using pencils made from the heartwood of an Eastern red cedar. So this year as you drive to a relative’s house or to a holiday party, take a second as you gaze out your window to consider the value of the common Eastern red cedar. Even though you may not soon add this tree to your garden, it is truly worth knowing.

Bundle up and go outside to enjoy the swishing sounds of many ornamental grasses and brightly colored berries on hollies and crabapples. If you need something more productive to do, the University of Tennessee Institute of Agriculture recommends these gardening tasks to brighten your winter or make your spring chores less hectic. Indoors In the Garden and Yard Convert your holiday poinsettia into a houseplant. Remove foil wraps and set it in a saucer or other water-capturing basin. Place plant in a bright sunny location and provide ample moisture. When the bracts' color start to fade and stems become leggy, cut them back in half. In the spring, move your plant outdoors. Plant indoor bulbs, such as amaryllis and paperwhites, to add a splash of color and fragrance indoors. Plant bulbs in potting soil, place pot in a bright sunny location, and lightly water until new growth appears. At the sight of new growth, cut back on saturating the soil but make sure the plant is receiving ample moisture. Bulbs should bloom in about six weeks. With the reduced amount of bright daylight, place houseplants in sunnier locations throughout your home and increase the time between waterings. Do not reduce the amount of water. Make sure birdfeeders are full so your finefeathered friends will have a sufficient food supply throughout the winter. Plant bulbs if you have not already done so. Naturalize them in your lawn and under trees or scatter them throughout the perennial border. Spring bulbs should go through a chilling process of at least twelve weeks to provide the best results. Visit your local garden center to ask about plant selections and order your seeds and plants. Start gathering seed-starting materials. Review notes, sketches, and photos of your garden from last growing season. Future success is often based on advance planning. Avoid use of salt-based products to melt snow or de-ice walkways and driveways. Salt is toxic to many plants. Use sand, sawdust, or cat litter. When temperatures are below freezing, avoid unnecessary contact with outside plant material. Frozen and iced plants are brittle, and limbs can break easily. If limbs are broken, prune them promptly to avoid tearing the bark and introducing disease and pests. Check perennials for frost heaving (uplifting from the soil surface). Apply additional mulch if needed. February is the month for pruning. Make sure pruning tools are sharpened and cleaned in preparation for next month. December 2010 4
