When pruning a crape myrtle, begin by selecting the main trunks you want to keep. Remove the rest by cutting them back as close to the soil line as possible. Then, prune the crown by removing branches that encroach on areas already occupied by other branches or branches that rub against each other. Removing some of the branches growing toward the center improves air circulation, and removing weak, skinny twigs that are thinner than a pencil can encourage stronger growth. Always cut the branch or twig back to its base.
Sprouts and suckers grow on crape myrtles throughout the year. Cut these all the way back to the soil line when they appear.Learn more about Trees & Bushes
