Q.Crepe Myrtle Tree Diseases
Last year I had two trees that began dropping their leaves in August. This year, right now, I have one Crepe Myrtle that has started shedding what appears to be healthy leaves. I see no pest on the tree, and the leaves look normal. No aphids, no black soot, no beetles, nothing that I can see. HELP!!!!

I suspect you have a pest infestation, likely aphids. These insects are sometimes difficult to spot, but just because you don't see doesn't mean they're not there. Treat the trees with neem oil.
