Episode 2101
Airs 7/5/12 and 7/8/12

On this edition of Volunteer Gardener, we’ll take cues on landscape design and effective use of color sweeps on a tour of the color garden at Cheekwood Botanical Garden. Also, Annette Shrader shows how an easy paint technique can transform a concrete container or garden ornament into an elegant ‘Old World’ look. Marty DeHart offers advice about picking the right blueberry shrubs for the best success, and how to amend the soil for good yields. Tammy Algood will have you reaching for your waffle iron frequently with her deliciously simple recipe for Citrus Zest Waffles.

Plants profiled were: Canna ‘Tropical Storm’, Zinnia (Profusion Series) ‘Red Knee High’, Pepper ‘Black Pearl’ and Miscanthus ‘Morning Light’

Marty had the following information about choosing and growing blueberries:
There are three types of blueberries: Northern High Bush, Rabbit Eye and Southern High Bush. Generally, you need more than one shrub to get berries. The exception to that is a variety called ‘Sunshine Blue’ which she recommended highly. Blueberries need and acidic soil and a sunny location to thrive. She recommended the following soil amendments for blueberry production: Soil Acidifier (elemental sulfer), WSM Woodland Soil Mix, and Holly Tone by Espoma.

Episode 2102
Airs 7/12/12 and 7/15/12

On Volunteer Gardener, we’ll join in the fun at a summer camp designed for junior gardeners. Julie Berbiglia find that the lessons are hands-on, and hands-in, with vegetable gardening, propagation, composting and design. Sheri Gramer helps us learn how to get a beautiful garden of flowers instantly by following some basics of good container design. Troy Marden takes us behind the scenes into the world of tropical plant hybridizing to learn what attributes are being bred into new introductions. New compact and showy specimens are hitting the market.

Julie’s segment was taped with the Davidson County Master Gardeners. For more information about their summer camp, visit www.dcmg.org and search the site for ‘Junior Gardener Day Camp’, or call UT Extension agent David Cook at 615.862.5995

Sheri’s segment was taped at Riverbend Nursery (provided plant material) with Barbara Wise.

Barbara Wise has written Container Gardening for All Seasons and it is available locally at Yarrow Acres and Riverbend Nursery. They are both located in Franklin, TN. Barnes & Noble and Books-a-Million also carry it. It is available online at Amazon and Target (online only).

Pointers about successful container gardening that Barbara shared: Use good potting soil or container gardening mix, not topsoil. She recommends Garden Magic Potting Soil. The basic recipe to follow when choosing plants for a container is use a thriller, a spiller and a filler.

Episode 2103
Airs 7/19/12 and 7/22/12

Sheri Gramer enjoys this summer’s Treehouses at Cheekwood featuring 7 kid/adult friendly interactive structures. Treehouses focuses on great works of literature with whimsical and traditional spins. Annette Shrader tours a garden beautifully designed to take optimum advantage of the space, and the lighting conditions. Troy Marden provides a plant palette that’s perfect for that spot down by the mailbox that is hard to water. Julie Berbiglia is in the historic Richland neighborhood of Nashville to learn about adding authenticity to a residence with historic landscaping.

Sheri’s segment was taped at Cheekwood Botanical Garden. The tree house exhibit runs now through 9/3/12.

Episode 2104
Airs 7/26/12 and 7/29/12

On this edition of Volunteer Gardener, Julie Berbiglia learns the many effects that several successive mild winters have had on plant disease, insects and weeds when she talks with a University of Tennessee extension agent. Then Annette Shrader visits with a hosta hybridizer to find out what characteristics are being bred into this popular plant. Marty DeHart tours a garden and can’t help but notice the pleasing plant combinations.

Tomato Spotted Wilt Virus by David Cook, UT Extension Agent
Environmental conditions this year have favored the presence of a viral disease of tomato. The information presented here is taken from a fact sheet written by Dr. Steve Bost, UT Professor of Entomology and Plant Pathology.

Tomato spotted wilt virus (TSWV) has been found in Tennessee crops each year since 1986. The primary crops affected are tobacco, tomato, peppers, and certain greenhouse ornamentals.
Symptoms: Symptoms vary, but usually begin with a blighting of young (upper) leaves, beginning with purple or brown spots on the leaves. Its appearance in the upper part of the plant distinguishes TSWV from fungal leaf blights, which often begin on the lower leaves. Purple to bronze streaks and rings may appear on stems. In older infections, stem surfaces exhibit tan to brown corky areas and tip dieback. Plants infected when they are small are stunted and pale, and leaves are rolled exhibiting purple veins on the undersides. Infected ripe fruit show noticeable yellow rings. Some fruit have a dark, rough ‘alligator’ skin.
Spread: TSWV is spread by tiny insects called thrips which pick up the virus by feeding on infected plants. TSWV has a wide host range, including many perennial weeds that can host the virus over the winter. Thus, there is a readily available source of the virus each year. If the virus and the thrips are present, the severity of the disease depends on the weather. Dry Spring weather is usually followed by problems with spotted wilt during the growing season, and preventive methods for the summer crop would be warranted.
Control: Many authorities suggest that infected plants not be removed, as doing so may cause more movement of the thrips than would occur otherwise. Furthermore, TSWV-infected tomato plants sometimes grow out of the condition and produce normal fruit. Insecticides with thrips activity have been shown to provide slight suppression of spotted wilt if applied early and frequently. Home gardeners are more limited in their choices, but pyrethroid products such as Ortho Bug-B-Gone and spinosad products such as Ferti-lome Borer, Bagworm, Tent Caterpillar, and Leafminer spray and Conserve (Southern Ag) would be the most likely to provide results.

Annette Shrader spoke to plant hybridizer Bob Solberg about what the future holds for hosta varieties.
