So the new crepe myrtle became thoroughly infested with aphids and I didn't get to them in time before sooty mold took over from all the honeydew.I've sprayed them now and will be diligent to keep them under control. Is there something I can do to remove that black mess from the leaves without harming the plant? Some sort of soap solution or is it better to spray with a fungicide? or a two pronged attack first with fungicide then some sort of soap solution to clean the leaves and bark.Ideas or suggestions would be greatly appreciated..
We simply remove the leaves, wash down the bark, soap won't hurt, but the leaves will die anyway, the wood needs to be clean and dry as soon as possible. Not sure if you can treat the ground for that stuff or not to do any good
