Azalea lower stems & leaves
Our very large azalea bush is dying. The leaves are covered with small pin size black spots and the stems have grey/black spots. Should the plant be removed? Or can it be saved?

This seems like an infection, and can likely be cured by applying wettable sulfur and dolomitic lime. This will help kill the problem, and replenish the soil's pH afterwords.
