The best thing about growing crepe myrtle is that this is a tree you can grow yourself from a cutting! The best way to propagate crepe myrtles if you want fast results is by using soft cuttings.
Calls are rolling in about what is this nasty black and white fungus looking stuff on my crape myrtles? Well guess what, it is not a fungus, and you do not have to cut your tree down to get rid of it.
