| Please help me identify what is going on and how to fix it. These little black spots are on every tree that I have. They are even on the ivy surrounding my backyard. I am able to peel off most of the black spots very easily. Almost like scales. Along with the black spots, the tops of a couple of trees seems to be wilting and almost have a wax/plastic like substance on the leaves. these are the types of trees that the black stuff is on:

| You said it yourself, scale. And maybe another thing or two. But the black scales are scale. Treat with all seasons horticultural oil and/or an insecticide. The leaves curling up are more like a psyllid, maybe Asian citrus psyllid. That's just a guess. The sticky stuff coating things is honeydew secreted by aphids, scale, and psyllid. |
