Crape Myrtle - sick or bugs?
We have a grouping of Natchez Crape Myrtles on the south side of our house. Late last summer they started looking like the photo below, dark leaves, fewer flowers, and dark staining on the gravel underneath.
I hired a new yard guy late last fall, a guy who worked many years for a local nursery before striking out on his own. He didn't have the benefit of seeing them with leaves, but based on his inspection of the branches and stains on the gravel, he diagnosed aphids or something like that, and said that he would spray for them this year. He has sprayed, but he was apparently wrong with his diagnosis.
I will post a couple of closeups as well.
Any ideas or suggestions would be much appreciated!
