Q.Flaky Mold on the Older Branches

Anonymous added on July 11, 2011 | Answered

We have moved onto a new property that has one red crepe myrtle tree on it. This tree has a flaky green mold attached to all of the branches except this year’s new growth. There are beautiful flowers on the new growth. What can I do to eliminate this mold and not hurt the new growth?
