Q.Many Of My Azalea Bushes Are Suddenly Dying. I Looked For Something That Matched What They Look Like But Don’t See Anything.
It’s not just one variety, it’s many varieties. At first I noticed one bush looked ‘funny’ over the winter and then as they started out of hibernation, I saw more branches on more bushes… and now I have a half dozen completely dead bushes. I have attached a picture of what might be the cause. Is there something I can treat them all with?
