Blooms turn brown rapidly. Fungus?
I am in North Carolina. I have a white azalea that is growing very well and puts out a beautiful show of white blooms. Unfortunately, every year they turn yellow, then brown quickly: perhaps a week or less. I thought this might be normal but on keeping track of the many azaleas in this area, I think they last for a month or much more. I recently heard about some disease, perhaps a fungus (I forgot), that causes this.
Can you tell me what and when to do something about this. I just thought of this site. the flowers died a month or more ago.
