Sequatchie Valley Master Gardeners June 2021 UT Gardens Plant of the Month The Eye-catching Trumpet Honeysuckle Submitted by Shalena Durkot, coordinator, UT Gardens, Crossville Lonicera sempervirens, commonly called trumpet or coral honeysuckle, is a climbing vine native to the eastern half of the United States. It is a real eye-catcher in the garden and is widely known to attract butterflies and hummingbirds. Trumpet honeysuckle cultivars can be found that will provide blooms throughout the growing season followed by small, red berries that are eaten by songbirds. The genus, Lonicera, is named for German botanist, Adam Lonitzer (Lonicer). The species, “sempervirens” means evergreen; however, this only holds true in milder climates of the Deep South. This species should not be confused with the terribly invasive Lonicera japonica. Although somewhat vigorous, trumpet honeysuckle does not grow or spread as rampantly as our native crossvine or trumpet creeper. Trumpet honeysuckle is a native climbing vine with Trumpet honeysuckle is easy to grow and thrives in zones 4 to colorful blooms that attract butterflies and 9. It prefers full sun but can tolerate some shade. Best bloom hummingbirds. Photo of specimen at the UT Gardens, production occurs with six hours of direct light. While it appreciates Crossville, by S. Durkot, courtesy UTIA. organically rich soils with good drainage, the vine will thrive with average, medium moisture, and neutral to acidic soils. Trumpet honeysuckle is also tolerant of clay, black walnut, and deer. The vine has no serious pest or disease problems, but powdery mildew and leaf spots may occur, particularly where summers are hot and humid and have been known to occur particularly where it gets less than ideal sunlight and air circulation. Aphids can occur on occasion. Pruning can be done throughout the growing season after its flush of blooms if needed. Trumpet honeysuckle is easily propagated by softwood cuttings taken in late spring or summer. The colorful twining vine grows to 20 feet, and it is suitable for fences, trellises, and arbors. It looks lovely cascading from retaining walls or left to sprawl as a groundcover on slopes and embankments. Trumpet honeysuckle’s tubular flowers are perfect for hummingbirds and other long-tongued insect pollinators. The plant is a larval host to spring azure butterflies and snowberry clearwing moths. The fall fruit is enjoyed by quail, purple finches, goldfinches, hermit thrushes, eastern bluebirds, and American robins. Some of the popular cultivars of trumpet honeysuckle are: • ‘Cedar Lane’- strappy bluish foliage, scarlet flowers with better resistance to aphids • ‘John Clayton’- yellow flowers The profusion of blooms produced by Lonicera • ‘Sulphurea’- yellow flowers sempervirens ‘Major Wheeler’ will cascade over any Recommended reblooming forms: structure, including fencing. Photo by C. Reese, courtesy • ‘Major Wheeler’- prolific scarlet flowers UTIA. • ‘Alabama Crimson’- deep red flowers • ‘Blanche Sandman’- orange-red flowers Specimens of ‘Blanche Sandman’ have performed well in the UT Gardens’ site in Crossville, also known as the Discovery Gardens. ‘Major Wheeler’ is recommended by the staff at the UT Gardens, Knoxville, and UT Gardens, Jackson. 2
Sequatchie Valley Master Gardeners June 2021 Gardening Tips “Gardening requires lots of water - most of it in the form of perspiration.” Lou Erickson July Gardening Here is your “to do” list for the garden for July. These tasks were submitted by Jason Reeves, horticulturist, and curator at the University of Tennessee Gardens in Jackson. • Many plants are easily propagated by layering. Hydrangeas, viburnums, weigela, trumpet honeysuckle, Carolina jessamine, and climbing roses are a few that will root if the stems are fastened down and covered with soil. • Start planning your fall vegetable garden. Late July is the time to start seeding your winter broccoli, cabbage, cauliflower, and brussels sprouts to be transplanted into the garden in mid-August. • You should be receiving fall nursery catalogs in the mail soon. Now would be the time to begin planning a new garden. • Raise the height of your mower to reduce stress on your lawn and to conserve moisture in the ground. For best results, mow 2 inches for Bermuda grass, 1 to 2 inches for Zoysia, and 2.5 to 3 inches for fescue. • July is a good month to prune “bleeder” trees like maples, dogwood, elm and birch, and other trees that “bleed” when pruned in winter. • Give your chrysanthemums and aster the last pinching no later than mid-July. • Keep your perennials deadheaded so they will continue to flower. Be sure to remove the fading flower down to a leaf node or new bud. • Cut back early planted annuals that are getting leggy or out of control by one-third to keep them looking good into the fall. Give them a shot of a water-soluble fertilizer. Good candidates include impatiens, salvia, sweet potato vine, trailing or ground-cover-type petunias, and herbs, like basil. • Avoid pruning spring-flowering shrubs from now until next spring. Anything you remove now will also be removing next year's flowers. Spring-flowering shrubs include azaleas, camellias, witch hazels, and rhododendrons among others. • Now is the time to prune overgrown oakleaf and mop-head hydrangeas. • Cut flowers for a bouquet early in the morning. Immediately place them in water. Good cut flowers include purple or white Echinacea (coneflower), Rudbeckia (Black-eyed Susan), zinnias, salvia, dahlias, sunflowers, Mexican sunflower, celosia, jewels of opar, cosmos, dill, fennel, Gomphrena (globe amaranth), Gaillardia, Monarda (bee balm), phlox, yarrow, ornamental grasses, and Artemisia. • Cut old flower heads off Hydrangea arborescens such as 'Annabelle' to get a second, but smaller, flush of flowers. • July is a good time to buy crapemyrtles. They are in flower now so you can be certain to get the flower colored desired. Crapemyrtles should not be fertilized after mid-July to allow them time to properly harden off by fall. • Keep birdbaths clean and filled with water through the hot weather, but be sure to control mosquitoes by eliminating sources of stagnant water.

Sequatchie Valley Master Gardeners June 2021 Box Tree Moth The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of box tree moth, Cydalima perspectalis, in the United States and Tennessee is a state that may have received infested boxwood plants. The box tree moth feeds mostly on boxwoods and can defoliate and potentially kill boxwood plants if left unchecked. Once the leaves are gone, larvae consume the bark, leading to plant death. Signs of infestation include silky webbing and possibly caterpillars located deep inside of the plants. Caterpillars, they can be upto 1.5 inches long Box tree moth caterpillars are green and yellow with white, yellow, and black stripes and black spots. The adult box tree moth has two color patterns. The most common has white wings with dark brown borders, while the dark pattern has solid brown wings with a white streak or spot on each forewing. Both have a distinctive white dot or mark in the middle of each forewing. Boxwoods appear in many landscapes in Tennessee due to their year-round green foliage and adaptability to changing weather. TDA recommends anyone who purchased boxwood plants within the last few months, inspect their plants for signs of the pest. If you suspect your boxwood plant has been infested, contact TDA’s Plant Certification Section at 615-837-5137. Adult moths can have a wingspan of 1.5 to 1.75 inches To learn more https://extension.psu.edu/box-tree-moth?fbclid=IwAR2uzMGr2IC- 2rOs6ingEyC5iEl9SgiPgi5JGF0boRrkDvBZ2z8UCJJ7a88 Photos Matteo Maspero and Andrea Tantardini, Centro MiRT - Fondazione Minoprio [IT] from Tennessee Dept. of Agriculture Facebook page.
