I included some pics of my 2-3 yr old crape myrtle Muskogee in Pensacola Fl. It appears to have a small amount of bloom and a spotty late bloom as well. It looks quite healthy other than some random yellowing leaves and these spots. Not all of the leaves are spotted or yellowed. I've never pruned it since I planted it. I was waiting for it to mature, then this winter I was planning on pruning. is it a mold or fungus? I have some knockout roses that had black spots and used Garden Safe Fungicide 3 spray and it solved my rose issue. Can I try the same fungicide on the Muskogee? Many thanks, Mike H
