Why Have My Azalea’s Stopped Blooming ?
My plants are 20 years old and not knowing much about plants and in the beginning they bloomed every year. However, not knowing anything about plants(especially these), I didn't do any kind of pruning. Now they have grown to over 10' high and last year they didn't produce any flowers and it looks like they won't this year either. Is there anything I can do about this or is it too late in their life? Any suggestions would be appreciated.
