Q.Crepe Myrtle Problem

Anonymous added on May 11, 2014 | Answered

I have 5 crepe myrtle trees, which have a white powdery substance on them. After a short time, a black substance appears on the leaves. I have had this problem for a couple of years and have sprayed them with several different things, but nothing seems to get rid of it. Any suggestions?
