Q.pruning crepe myrtles
My driveway is lined with white crepe myrtles. However, over the last 2 or 3 years, a few of them have become multi colored. Can I cut away the colored portion now while it’s blooming?
Sounds like the graft is reverting to the original color on these. You can prune them out but it may affect next season's blooms. Here is more information on pruning crepe myrtles: https://www.gardeningknowhow.com/ornamental/trees/crepe-myrtle/pruning-crepe-myrtle-trees.htm
