Did You Know?
1. Crape myrtles are not actually true myrtles, but rather they belong to the genus Lagerstroemia, making them part of the family Lythraceae.
2. The colorful bark of crape myrtles is caused by a unique layer of cells called the periderm, which continuously peels off in thin sheets, revealing different shades of cream, tan, and cinnamon.
3. The practice of pruning crape myrtles into a “crape murder” shape, where the branches are cut back aggressively, is actually harmful to the tree’s overall health and can hinder its natural growth pattern.
4. Crape myrtles were introduced to the United States from their native Southeast Asia in the late 18th century and have since become one of the most popular ornamental trees in the southern states.
5. Crape myrtles are known for their ability to attract various pollinators such as butterflies and bees, making them an excellent addition to any garden or landscape for those interested in promoting biodiversity.
Avoid “Crepe Murder” – Don’t Ruin Your Crape Myrtle Tree!
Many people are guilty of committing “crepe murder” by unnecessarily reducing their crepe myrtle trees to ugly stumps. This practice not only ruins the aesthetics of these beautiful trees but also hampers their overall health. Pruning a crepe myrtle should be done with the primary goal of maintaining its natural form, promoting strong branches for upright flowers, and highlighting the smooth, multi-toned bark. Unfortunately, cutting back the tree to thick stubs each year prevents achieving these goals and transforms the tree into an unattractive fencepost or hat rack. To avoid committing “crepe murder,” it is crucial to understand how to properly prune a crepe myrtle and approach it with care and consideration.
Pruning Goals: Shape, Strong Branches, And Beautiful Bark
Before we delve into the specifics of pruning a crepe myrtle, it is essential to understand the goals of this process. Firstly, shaping the tree to maintain its natural form is crucial. Crepe myrtles are known for their elegant and sculptural appearance, and proper pruning helps enhance and showcase this unique shape. Secondly, promoting strong branches is essential to ensure the tree can support the weight of its flowers. Upright flowers not only enhance the beauty of the tree but also make it more resistant to damage from wind or heavy rainfall. Lastly, revealing the smooth, multi-toned bark on the mature trunks and branches of the crepe myrtle adds another layer of visual appeal to these trees. Achieving these objectives requires careful pruning techniques and avoiding common mistakes.
Study Before You Prune – Be Conservative And Deliberate
Properly pruning a crepe myrtle begins with studying the tree and understanding your goals. It is crucial to approach pruning conservatively, as you can always cut more later if needed. Carefully assess the tree’s structure and limit the number of trunks to three to five for a harmonious appearance. When pruning, cut back to a larger trunk branch as close to the soil as possible. Remove any suckers around the base of the tree to maintain a clean trunk. To maintain the tree shape, remove branches below the 5-foot mark. Cut all crossing, rubbing, and dead branches back to another branch, an outward-facing bud, or the branch collar. By being deliberate and considerate in your pruning approach, you can ensure the long-term health and beauty of your crepe myrtle.

Essential Tools And Best Time For Pruning
To successfully prune a crepe myrtle, it is important to have the appropriate tools on hand. Essential pruning tools include a hand pruner for smaller branches, loppers for larger branches, and pole pruners or a pruning saw for hard-to-reach areas. These tools will enable you to make clean and precise cuts, minimizing damage to the tree and promoting proper healing.
As for the best time to prune a crepe myrtle, late winter is generally considered ideal. February, in particular, is often recommended. This is because the tree is leafless during this period, making all branches visible and accessible for pruning. Pruning during late winter does not reduce blooming and may even increase it, as the tree blooms on new growth. By pruning during this time, you can shape the tree without sacrificing its potential for beautiful blooms.
Proper Pruning Vs. Ugly Stumps – Mistakes To Avoid
One of the most common and detrimental mistakes in crepe myrtle pruning is trying to reduce the tree’s height by lopping off the top. This practice leads to the formation of ugly stumps and prevents the development of attractive bark on the mature trunks. Moreover, it results in weak branches that are incapable of supporting flowers, causing them to bend down to the ground.
To avoid these unsightly outcomes, it is crucial to start conservatively and methodically tackle branches in a specific order. By following proper pruning techniques, you can preserve the beauty and health of your crepe myrtle.
- Pruning a crepe myrtle should be approached with care and consideration.
- Understanding the goals of pruning is essential to ensure the maintenance of the tree’s natural form, promote strong branches for upright flowers, and reveal the beautiful bark.
- Use the right tools and prune in late winter for optimal results.
- Avoid common mistakes such as lopping off the top of the tree.
- Be conservative in your pruning approach to retain the tree’s beauty and ensure its long-term health.
Remember, resist the urge to commit “crepe murder” and instead embrace the art of proper crepe myrtle pruning for a stunning and healthy tree.

Frequently Asked Questions
How do you trim crepe myrtles to grow taller?
To encourage your crepe myrtles to grow taller, it is important to selectively prune the lower branches. Start by removing the side branches along the main trunks, focusing on a height of around four to six feet. It is crucial to avoid pruning up to a height that exceeds half of the entire tree’s height. By trimming the lower branches, you can raise the canopy, promoting vertical growth and creating a taller and more aesthetically pleasing crepe myrtle.
What happens if you don’t trim crepe myrtle?
If crepe myrtles are left untrimmed, they are likely to produce an abundance of flowers. While pruning may result in fewer flowers, the ones that do bloom will be larger. Therefore, by choosing not to trim crepe myrtles, you can enjoy a profusion of smaller flowers, whereas pruning them will lead to fewer but larger and more visually striking flower clusters. It ultimately depends on personal preference whether one prefers abundant smaller flowers or fewer but larger blooms.
What is the best time to trim a crepe myrtle?
The optimal time to trim a crepe myrtle is in late winter, specifically during the month of February. This is because the tree is devoid of leaves, making it easier to identify and assess each branch. Additionally, pruning during this period does not hinder blooming as the crepe myrtle blooms on new growth, and in fact, it may even enhance the blooming process. Therefore, February proves to be the most suitable month for effectively trimming a crepe myrtle for optimal growth and blossoming.
How fast do crepe myrtles grow after pruning?
After pruning, crepe myrtles have the remarkable ability to rejuvenate and grow rapidly. With renewal pruning, where the tree is cut down to the ground, they can experience a fresh start. Within the span of two to three years, crepe myrtles will regrow vigorously, becoming healthy and strong once again. This remarkable growth rate showcases the resiliency of crepe myrtles and their ability to quickly recover from pruning.
