General
1. What is a rain barrel? Can I use rain water collected from my home's downspouts on my landscape plants?
2. This is a viewer bought jelly crystals in a store, those that expand to a hundred times their original size in water. They wonder whether they can actually put it in their garden soil to retain moisture or will it do any damage to the plants?
Trees & Shrubs
1. Large sections of the outer branches on my holly bush have brown, dried leaves this spring. It was fine in the fall, but now I'm finding all these brown leaves. What's going on?
2. A couple of evergreen questions with similar problems, even though the trees are different. Forty 1-year old pines are turning yellowish on the south side of the trees in late April. The south side does get more wind than the other side. The second tree is an arbovitae that is also turning brown. What is happening?
3. What should I use for mulch around and under trees and plants to suppress weeds? Which is better: wood, rubber, or rocks? In addition, do I use landscape fabric?
4. A viewer has two oak trees with iron chlorosis. The trees are very large, but the leaves are light green. They want to know if there is a newer treatment than iron injections or inserting tablets to manage chlorosis.
Vegetables
1. When and where to I pick morel mushrooms?
2. My potatoes have developed small green, round "tomatoes" at the top of the plants. Are these really tomatoes?
