I have what looks like the same disease or insect on several plants. They started on my fall blooming camellias last year, which are three years old. I sprayed them with horticultural oil throughout the summer and they seemed better but now they look like they’re dying. The same thing Seems to be happening to my jasmine, my photinia and a very large spring blooming camellia. A separate question involves crape myrtle bark scale. I had a very small infestation last summer. The trees were treated professionally in the fall and again last month. There are still small remnants. Is this something that I need to treat for regularly?
