Crape myrtles are cherished for their eye-catching blooms and elegant shapes, yet a myth persists about their care. Many people falsely believe that severely cutting back crape myrtles to bare trunks will result in a more spectacular display of flowers. In truth, this harmful practice — commonly known as “topping” — has the opposite effect. Topping shortens the bloom time, delays flowering and weakens the tree, increasing its susceptibility to pests and diseases that can devastate its vitality and beauty.

For those in Rowan County dedicated to nurturing their crape myrtles, late winter — specifically February and March — is the prime time for pruning. Instead of forcing your tree into unnatural forms, emphasize its innate beauty. Naturally, crape myrtles flourish as striking, vase-shaped trees with multiple trunks. As you prune, look for branches that grow inward or cross one another; removing these will encourage healthy airflow and light penetration, leading to more substantial, vibrant growth.

When removing a branch, cut just above the swollen collar where it meets the trunk. This technique promotes healing and ensures a clean cut. For thicker branches, a sturdy pruning saw is essential for achieving precise, smooth incisions. If it’s been a while since your last pruning, you may have several branches to remove; however, be cautious about making drastic cuts close to the ground, as this can lead to excessive new growth that appears bushy and unmanageable.

Trim small twiggy branches and seed pods using hand pruners for a tidier appearance. While this isn’t essential for the tree’s health, it can enhance the size of flower clusters and help your crape myrtle look its best.

Learn how to correctly prune a crape myrtle at the Crape Myrtle Pruning Demonstration. Join us at Granite Quarry Civic Town Park on Saturday, Feb. 15, from 9 a.m. to 11 a.m. The town of Granite Quarry and N.C. Cooperative Extension are sponsoring this program. I will be leading a hands-on demonstration on how to prune crape myrtles.
