My dogwood trees have shriveled leaves at the ends of branches.
At first I thought they were thirsty but now I notice some of the
other leaves have a white, dusty-looking material on them. Will
they survive? Should I treat the trees?

There are a couple good sites on diseases of Dogwood -
http://www.ext.vt.edu/pubs/plantdise...1/450-611.html, and
http://www.wwaytv3.com/global/story.asp?s=2293840 popped up. Sounds like
Powdery Mildew from the symptoms. I've heard a bit about a fungus that's
spreading and killing Dogwoods (probably Anthracnose) but since that causes
spots, you probably don't have that.
