Dead Branches on Azaleas
When we bought our house a couple of years ago, we inherited a beautifully landscaped yard; however, it had been neglected for a couple of years. There are quite a lot of azaleas in the front, on the sides, and around back, and all look to have been established probably 10-15 years ago. They bloom, profusely, each spring.
As I began trying to get the yard back to its original beauty, I found that many azaleas had dead branches, so I pruned them out. That was three falls ago. Now, for the past two springs, I have found that although I pruned all the dead branches in the fall, there seems to be more.
What could be causing these branches to die? There are so very many azaleas that I'm not sure how to go about fertilizing them, if that is needed. Do you have any advice as to what I should do to keep these branches from continuing to die?
Thanks for any advice you can offer!
