Q.azaleas
A lot of my azaleas have white “stuff” on their limbs. All I can find online is information about white mildew on the leaves. Do you know what’s going on with my azaleas and what I could buy to get rid of it?
Appreciate your help.
This sounds like a case of Azalea Bark Scale.
Here are some links with more information and how to treat.
