The Right Way to Trim and Prune Crepe Myrtles in North Texas
Crepe myrtles (Lagerstroemia indica) are one of the most beloved ornamental trees in North Texas, offering stunning summer blooms, attractive peeling bark, and vibrant fall foliage. However, improper pruning can damage these trees and reduce their flowering potential. Unfortunately, many people engage in the harmful practice known as “Crepe Murder,” where the tree is aggressively cut back to stubs, leading to weak, unattractive growth.
If you want your crepe myrtle to flourish year after year, follow these proper pruning techniques to maintain its natural beauty and health.
When to Prune Crepe Myrtles in North Texas
The best time to prune crepe myrtles is late winter to early spring, typically between mid-February and early March. At this time, the tree is still dormant, making it easier to see its natural structure and make precise cuts. Additionally, pruning before new growth begins allows for optimal flowering in the summer.
Did You Know?
Crepe myrtles bloom on new wood, meaning that any new growth that appears in the spring will produce flowers in the summer. This is why timing your pruning correctly is essential.
The Right Tools for Pruning
Using the correct tools ensures clean cuts and prevents damage to the tree. Here are the recommended tools:
- Hand pruners (for small branches under ½ inch in diameter)
- Loppers (for branches up to 1.5 inches in diameter)
- Pruning saw (for larger branches over 2 inches)
- Pole pruner (for hard-to-reach areas)
Always ensure your tools are sharp and disinfected before and after use to prevent the spread of disease.
How to Correctly Prune Crepe Myrtles
Follow these simple steps to maintain the beauty and health of your tree:
1. Remove Dead, Diseased, and Crossing Branches
Start by cutting out any dead or diseased wood. Then, look for crossing branches that may rub against each other, causing damage. Always cut at the base of the branch without leaving a stub.
2. Maintain a Natural Shape
Crepe myrtles have a naturally graceful, multi-trunked form. Instead of chopping the top off, remove unnecessary interior branches to allow better airflow and light penetration. This promotes a strong structure and abundant blooms.
3. Thin Out Small, Weak Growth
Suckers (small shoots that emerge from the base of the tree) should be removed regularly. Also, thin out small, weak interior branches to enhance the tree’s overall appearance and prevent overcrowding.
4. Avoid “Topping”
Topping (cutting the tree back to knuckles or stubs) leads to weak, spindly growth that does not support abundant flowering. Instead, make selective cuts at natural branching points to preserve the tree’s beauty.
Did You Know?
Topping crepe myrtles forces excessive, weak growth that is more susceptible to disease, pests, and breakage. A properly pruned crepe myrtle can live for 50 years or more, while a topped one may struggle with health issues.
Common Pruning Mistakes to Avoid
- Over-Pruning (Topping or “Crepe Murder”) – This results in ugly stubs, weak regrowth, and fewer flowers.
- Pruning Too Early – Cutting too soon in the winter can make the tree vulnerable to freeze damage.
- Using Dull or Dirty Tools – Dull tools make ragged cuts, and dirty tools can spread disease.
- Removing Too Many Lower Branches – While some minor shaping is okay, over-pruning the lower canopy can lead to sun damage on the trunks.
How Pruning Affects Flowering
Pruning impacts flowering by stimulating new growth. Since crepe myrtles bloom on new wood, properly pruned trees will produce abundant flowers. However, excessive pruning can result in fewer blooms.
If a crepe myrtle is left unpruned, it will still flower—but proper pruning enhances its natural beauty and flowering potential.
Did You Know?
Some crepe myrtle varieties, like the Natchez or Muskogee, can grow over 20 feet tall. Instead of pruning to keep them small, choose dwarf or compact varieties if you want a shorter crepe myrtle.
Final Thoughts: The Right Way to Trim and Prune Crepe Myrtles in North Texas
Pruning crepe myrtles correctly is key to their long-term health and beauty. By pruning in late winter, using the right tools, and avoiding excessive cutting, you can ensure a stunning display of flowers every summer.
Properly maintained crepe myrtles not only enhance your landscape but also require less maintenance over time. So, skip the “Crepe Murder” and embrace the art of natural pruning to enjoy these magnificent trees for decades.
