My Azaleas have yellowing leaves that appear as if the green has been partially scraped off with sandpaper. There are dark shiny spots on the undersides of the leaves. What is causing this to occur and how can I stop it?
|The yellowing on your Azaleas leaves is from the feeding activity of Azalea Lacebugs. The shiny black spots on the undersides of the leaves are excrement from these pests. Lacebugs are tiny insects with lacy clear wings that are often unnoticed because they feed on the underside surface of leaves.|
