I have an azalea very similar to "northern lights", which produces red flowers. since about three years it produces less and less flowers. This spring only one button looks like its going to bloom. Most of them look dry and dead. I noticed last summer that the leaves get brown spots. those spots are dry and bumpy looking. Even the leaves don't grow on every branch now. I have tried cutting the infected areas but it gets worse every year. Is there a way to save it?

Welcome! Bev was right, I'm moving this to the trees and shrubs section! Glad to have you here!
