So, I may wait until early spring next year to spray the affected
trees. I hate that they won't bloom tho.

I'm by no means a dogwood expert or a fungus expert, but my experience
with powdery mildew leads me to beleive that you're worrying
unneccesarily - or at least prematurely.

I'm guessing that this is a result of the cool spring and that it will
clear up this summer. I'll be happy to take a $50 bet that it won't
kill your trees, and that they -will- bloom next year, and that if you
call your extension agent he will -not- recommend spraying for it.
