Stop Topping Your Crape Myrtles — And What to Do Instead

Drive through any Dallas neighborhood in late winter and you'll see it everywhere: crape myrtles cut down to ugly, knobby stubs. Arborists call it "crape murder," and it's one of the most common — and most unnecessary — tree care mistakes in North Texas.

The frustrating part is that crape myrtles are one of the most forgiving trees you can plant. They don't need heavy pruning to thrive. In fact, the less you cut, the better they look.

Here's what you need to know.

Crape murder is the practice of cutting crape myrtles back to large stubs — sometimes removing most of the canopy — in late winter or early spring. The result is a tree that looks like a hat rack for several months, then explodes into a mass of weak, whippy new growth that flops over under the weight of the blooms.

It's done for a few reasons: people think it makes the tree bloom more, they want to keep it a certain size, or they're just following what their neighbors do. None of these are good reasons, and the practice causes real harm.

When you top a crape myrtle, you remove the natural branch structure the tree spent years developing. The response is a flush of fast-growing water sprouts from the cut ends — dozens of weak shoots that are poorly attached and prone to breaking. The tree spends enormous energy trying to recover, and the result is never as attractive as an unpruned tree.

Over time, repeated topping creates large, ugly knobs at the cut points (called "crape knuckles") that never go away. The tree's natural form — graceful, multi-stemmed, with attractive exfoliating bark — is permanently disfigured.

And here's the thing: topping doesn't make crape myrtles bloom more. They bloom on new growth regardless. A properly pruned — or unpruned — crape myrtle will bloom just as heavily as a topped one, and it will look dramatically better doing it.

Crape myrtles need very little pruning. Here's what's actually worth doing:

Remove suckers and basal sprouts. These are the small shoots that come up from the base of the tree. Remove them as they appear throughout the growing season — they drain energy and clutter the base of the tree.

Remove crossing or rubbing branches. If two branches are rubbing against each other, remove the weaker one. This improves airflow and prevents wound development.

Thin the interior. If the canopy is very dense, removing a few interior branches improves airflow and light penetration, which reduces disease pressure.

Remove seed heads (optional). Cutting off the spent flower clusters after blooming can encourage a second flush of blooms. This is light work — you're removing small seed pods, not major branches.

That's it. A mature crape myrtle that's been left to grow naturally needs maybe 20–30 minutes of attention per year.

The best time to prune crape myrtles in North Texas is late winter — February through early March — just before new growth begins. You can see the branch structure clearly, and any cuts will be quickly covered by new growth.

Avoid pruning in fall. Late-season pruning can stimulate new growth that gets damaged by the first freeze.

Light cleanup (removing suckers, deadheading spent blooms) can be done any time during the growing season.

This is the most common reason people top crape myrtles — they planted a large-growing variety in a small space, and now it's outgrown the spot.

If that's your situation, you have a few options:

Selective reduction pruning. Rather than topping, a skilled arborist can reduce the height of the tree by cutting back to lateral branches, maintaining a natural form. It takes more skill than topping, but the result looks far better. This is exactly the kind of work our tree trimming service specializes in.

Remove and replant with the right variety. Crape myrtles come in sizes from 18-inch dwarfs to 30-foot trees. If the variety is genuinely wrong for the space, replacing it with a compact variety is often the best long-term answer.

Learn to live with the size. Crape myrtles are beautiful large trees. If the size isn't causing a real problem — blocking a window, growing into a structure — consider letting it grow.

Crape myrtles, redbuds, and other flowering trees should be trimmed right after they bloom — not before. For a broader look at timing across all tree types, see our guide on how often to trim trees in Dallas.

Crape myrtles are one of the best trees you can plant in a Dallas yard. They're drought-tolerant, heat-loving, long-blooming, and low-maintenance. The only thing that ruins them is over-pruning.

This year, put down the chainsaw and let your crape myrtles do what they do naturally. You'll be glad you did.
