Flowering Pear trees. I have some mature "Chanticleer" flowering pears. For the last 2 years, the new foliage has emerged with curled leaves and a white, cottony substance. This condition seems to lessen with the hot weather, but the foliage doesn't seem to totally look healthy like when the trees were younger. What is it and can it be treated?

Difficult to diagnose with just that description. It could be powdery mildew from infected buds that infects newly emerging leaves.
Here is a description from PNW Online Plant Disease Management. Go to http://plant-disease.ippc.orst.edu/disease.cfm?RecordID=806 and see if this is what you have.

- Whenever I go into the supermarket in the summer time I see people picking out watermelons and talking about bee stings as indicators of a good melon, but I thought bees only sting when threatened and that the sting contains a venom. Is there any correlation between the marks on watermelon and bees? Adam
- Just moved to where we have a very large backyard. I want to plant a large variety of fruit trees, but I don't know what will grow well in this climate. What types of fruit grow best in the Salt Lake area? (eg peaches, apples, nectarines....?) And which kind of each fruit would you suggest? I'm also new to this, so where should I go to buy the trees and find info on how to grow them correctly?

- Our blue spruce has been around for 30 years. but the new buds have no needles and they are brown. Even up the center of the tree is brown with no needles. My father has put a bed of rocks around it and I am not sure if it is affecting it. We also had two crimson maples and they lost all of their leaves half way through summer. This year there are no leaves at all. Do the trees have disease?

- We recently bought a home in Salt Lake city. The parking strip has very hard soil and weeds mixed with grass. Should we till it under and start over or air-rate it, keep it watered and sprinkle some grass seed on it in the fall or spring? We planted a sycomore tree (Bloodgood London Plane) and I think we stressed it by overwatering. About 50% of the leaves look sun scorched, some very dry and other leaves are green, full and lush, will it snap out of it? Should I air-rate the ground with a pitch fork around it?
