Crape Myrtle Care in Austin: Why 'Crape Murder' Is Killing Your Trees

Crape Myrtle Care in Austin: Why ‘Crape Murder’ Is Killing Your Trees

‍

Drive through any Austin neighborhood in January and you’ll see them: crape myrtles cut back to thick, knobby stubs, their natural shape completely destroyed. Arborists call it “crape murder” — and it’s the single most common and damaging tree care mistake in Central Texas. Crape myrtles are one of Austin’s most beautiful flowering trees when allowed to grow naturally. Here’s what’s actually going on, and what proper care looks like.

‍

What Is Crape Murder and Why Does It Happen?

‍

The Practice

‍

Crape murder refers to the annual heavy topping of crape myrtles — cutting the main trunks and major branches back to stubs, typically in late winter. The result is a tree with swollen, knobby cut points at the top of each trunk, and a burst of weak, fast-growing shoots that produce flowers in summer. Many homeowners do it because they’ve seen it done, because a landscaper told them it’s necessary, or because they believe it produces more flowers.

‍

None of Those Reasons Hold Up

‍

Crape myrtles bloom on new growth regardless of whether they’re topped. An unpruned crape myrtle produces just as many blooms — and often more — than a topped one, while maintaining its natural vase shape, attractive peeling bark, and structural integrity. Topping does not produce a better tree. It produces a disfigured tree with permanent knobs, weak branch attachments prone to storm damage, and a compromised natural form that can never fully recover.

What Proper Crape Myrtle Pruning Actually Looks Like

‍

Select the Right Size for the Space

‍

Most crape murder happens because the wrong size variety was planted in the wrong space. Crape myrtle varieties range from two-foot dwarf shrubs to 30-foot trees. When a large-growing variety gets planted under a power line or in front of a window, homeowners feel compelled to cut it back every year to keep it contained. The real fix is planting a size-appropriate variety from the start — or replacing an oversized plant with one that fits the space naturally.

‍

What You Actually Should Prune

‍

Crape myrtles benefit from light corrective pruning in late winter — but that means something very different from topping. Remove crossing branches that rub against each other, eliminate any branches growing inward toward the center of the canopy, take out suckers from the base, and remove seed pods from the previous season if desired. These targeted cuts improve airflow and structure without destroying the tree’s natural form. The goal is to enhance the tree’s natural shape, not override it.

Recovering a Topped Crape Myrtle

‍

Can It Be Fixed?

‍

A crape myrtle that has been topped for many years can be partially rehabilitated, but the knobby stubs at the cut points are permanent. The best approach is to stop topping immediately and allow the tree to grow naturally from that point forward. Select the strongest, best-positioned shoots from each stub and remove the rest, gradually working toward a more natural branching structure over several seasons. It takes patience, but the tree will be significantly healthier and more attractive within three to five years.

‍

When Replacement Makes More Sense

‍

If a crape myrtle has been severely topped for more than a decade and the knobs are very large, replacement with a correctly-sized variety is often the better long-term choice. A new crape myrtle planted in the right location and allowed to grow naturally will surpass a rehabilitated one in appearance and health within a few years. At Agave Tree Services, we can assess your crape myrtles and give you an honest recommendation on whether to rehabilitate or replace — and we’ll never suggest topping as a maintenance strategy.
