I bought a potted crape myrtle that has 5 stems that are 1″ to 1 1/2″ in diameter each.
I don’t know whether 5 trees growing so close together is a good idea for the long run.
Can they be separated safely? They have probably been growing together in this big plastic pot for a long time
This is the appropriate growing pattern for Crepe Myrtle.
Do not attempt to separate the branching.
Here are some articles that will refresh you on growing and caring for Crepe Myrtle.
