Q: We have a sweet cherry in our yard. Can a cutting from it be grafted onto a wild cherry? A: It may be possible, but every wild cherry is different and the graft (or bud) may not take. The way to find out for sure is to try it. Q: How can I keep ants from getting on my strawberries without using chemicals? A: I don't know of a good way to control ants without using chemicals. On the other hand, the ants do not harm strawberries. Chances are they are feeding on aphids that live on strawberry roots. Q: My wisteria vine is taking over the place. Can it be pruned? A: The Chinese wisteria can be pruned severely and blooms as well as or better than if left unpruned. The Japanese wisteria blooms better if left unpruned. Flowers of the Chinese variety are very fragrant, those of the Japanese only slightly so; blossoms on the Chinese open before the leaves appear, those of the Japanese develop with the unfolding leaves. Q: My candytuft didn't bloom very well this spring. What can I do to help it? A: Cut perennial candytuft back to about six inches soon after the flowers fade. If it isn't sheared, the flowers go to seed and energy is used up in the process, often resulting in poor flowering the following spring. Also fertilize it with 5-10-5 fertilizer, five pounds per 100 square feet of area. Q: I have a snake plant (Sansevieria trifasciata) with a pretty flower on it and everybody I tell about it tells me it doesn't bloom. Is there something pretty unusual about it? A: It is pretty but not unusual. There are about 34 different kinds of Sansevieria and all of them have been known to bloom. Q: In the spring every year, as soon as the weather gets warm, a lot of weeds appear in my vegetable garden, some of which I have never seen the likes of before. Is it possible that their seeds could have been in the fertilizer? A: Weed seeds can accumulate in the soil, brought in by wind, water, animals or man himself. They have a remarkable ability to survive buried in the soil for years, unable to germinate for lack of light. When the soil is cultivated, bringing them close to the surface, they seemingly explode into growth. Many weed seeds will survive in the soil 20 years and longer. Q: Can Benlate be applied to most shrubs to protect them from diseases? A: There are some diseases on some plants for which Benlate can be used effectively and many for which it does no good. First find out what the disease is, then read the label and find out whether the chemical is recommended for that particular disease on that kind of plant -- and, if so, how to apply it.
