Mold on Trunk

Question

I live in northern Virginia. I was looking at the crepe myrtles in our backyard this morning and noticed the lower third of the trunk on one of the trees looks reddish brown. The other two trees look normal. Any suggestions?

Answer 1

It is most likely lichen. Nothing to worry about and very normal. If you do want to get rid of it, here is more information: https://www.gardeningknowhow.com/ornamental/fungus-lichen/treatment-tree-lichen.htm
