|I have a mature azalea garden, which was pruned heavily. Most are Formosa.
Profuse growth occurred at ground level. Work removing this was laborous, and it is beginning to reoccur.
Plants are mulched well.
Can this be prevented?
|I'm afraid Formosa azaleas tend to have a suckering growth habit, especially when heavily pruned. Pruning encourages new growth and that's why your azaleas are developing new suckers. There's really not much you can do to discourage this natural tendency. I've found that when the suckers are young they are tender and easy to remove. Try pruning the new suckers out as soon as they begin to develop and they should be easier to remove. Wish I had other solutions for you!|
