What to do for crepe myrtle sooty mold?
I had what I thought was sooty mold that formed late this past summer on one of my crepe myrtles, and was starting to spread to another one until fall arrived. It was a black substance that coated the leaves and trunks. The trees are small, and I am going to trim and shape them here in a few days for the desired shape I want them to grow into. Would right after this trimming be a good time to spray them for this mold? What should I use? Is dormant spray that I use on my peach trees ok?
Any and all non-condecending help will be greatly appreciated.
