Have you ever noticed the bark falling off of your Crape Myrtles? Usually it ends up in a big pile at the base of the tree. You may have also noticed that the bark is a different color after this happens. There’s no need to worry about all of this, it’s just the tree going through it’s normal life cycle. This process of bark shedding is usually you don’t see until the tree is mature. It also isn’t something you may see every year as well. The only real issue is it creates a mess that you may want to clean up. Hope this helps!
