Troy Marden tours an expansive residential garden featuring 800 hosta varieties as well as some unique plant specimens that create a horticultural treasure. Marty DeHart has an important warning for homeowners with shrub roses. Annette Shrader demonstrates how she prunes crape myrtles so the showy bark is featured. Julie Berbiglia learns how to grow plants successfully using hydroponics.
From the Nashville Rose Society website:
ROSE ROSETTE Also known as 'Witches' Broom'. This deadly affliction is 100 percent fatal. So if you see it, just dig up the plant and remove it from the garden as soon as possible, as the mites which spread the infection are present in the plant. There is NO cure for Rose Rosette. This affliction has three stages. The first stage is rapid, vigorous growth characterized by unusually dense formation of prickles on stems and canes. Canes appear overly large and purple or deep red in color. New leaves appear distorted and crinkled, often purple or deep red. The leaf stems may appear flattened and look almost like leaves. The second stage is the development of lateral growth having closely spaced internodes leaf buds. When leaf buds open, they become distorted or even fail to fully open, giving an appearance of rosettes. The third stage is characterized by spindly, chlorotic stem growth. Roses may show symptoms in as little as 3 weeks after infection, or they can have an incubation period of up to a year or more.
The symptoms of this affliction are described as 'virus like', because the exact actual organism which causes Rose Rosette has not actually been identified as of yet. The disease agent of Rose Rosette is transmitted from plant to plant by a tiny microscopic sized, wooly mite called Phyllocoptes fructiphilus. This is a type of mite called an eriophyid mite. This is NOT like a spider mite.
Hybrid Teas are less likely to be used as hosts by this mite. Heavily pruned roses seem to have the fewest problems. This disease was first detected in the 1930s in wild roses growing in the mountains of California and Wyoming. Then it spread to stands of Rosa multiflora, an almost perfect host, and moved across the country and into the Midwest. In the late 1970s and early 1980s, it swept like a wildfire up the Ohio River valley and into West Virginia. Today, it’s endemic wherever wild multiflora roses are found This viral infection is most common now in the Midwest where Rosa multiflora hedges are frequently planted and become infected.
Treatment: Just remove the infected rose and burn or destroy it. Same with the soil around it where the mites might over-winter. Prevention is possible by controlling mites, as this is how the virus is transmitted to the rose. But you should realize that miticides and other measures commonly used for treating spider mite infestations aren’t effective because this is a different type of mite. If it is a big problem in your garden you might want to keep hybrids of Rosa multiflora out of your garden. Many budded or grafted roses are on Rosa multiflora root stock, which needlessly worries some gardeners. Although Rosa multiflora is a host for the disease and for the eriophyid mite, a rose on multiflora roots is no more susceptible to rose rosette than it would be if it were on its own roots or on another type of root stock. It is apparently the top growth and specifically the petiole-cane junction that determines susceptibility.

On this edition of Volunteer Gardener, Julie Berbiglia introduces us to the ambitious ‘can do’ community advocate behind the Bellevue Edible Learning Lab (BELL garden). This one acre plot features sustainable garden practices such as water catchment, composting, and pest control. Later, we’ll visit both the artist and the landscaper who have combined talents to fill a blank garden canvas with color, texture and structure. Jeff Poppen demonstates the efficiency of gardening the square foot way.

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.
