Small Green Moss on Crape Myrtle

Anonymous added on September 19, 2011 | Answered

I have a crape myrtle in my front yard that is approximately 10-12 feet tall. All of the multiple trunks have a small green moss-like growth on them. I have sprayed the tree several times with a fungicide, but this is still on there, in addition to black soot on the leaves. Is my tree ok? What should I do for this tree? Our tree was planted by the developer when our home was built 3 years ago.

The moss is likely lichen, and is harmless. This article has more information:

The black substance is sooty mold, and it is not harmless. This article will help you with treating that:
