How to Prune Crepe Myrtles in Tulsa
Crepe myrtles (Lagerstroemia indica) are a beloved staple in Tulsa landscapes, known for their vibrant summer blooms, striking peeling bark, and graceful structure. Proper pruning is essential to ensure healthy growth, abundant flowering, and a naturally beautiful shape.
When to Prune Crepe Myrtles in Tulsa
The best time to prune is late winter to early spring (late February through early March). By this time, the tree is either dormant or just about to break dormancy, making it easy to see its structure and shape it before new growth begins.
Too Early in Winter
Fresh cuts can be damaged by unseasonably cold temperatures.
Too Late in Spring
If buds have already begun to form, pruning can stress the tree and reduce blooms.
Summer or Fall Pruning
This can remove flower buds and result in fewer blooms next season.
Understanding Crepe Myrtle Growth Habits
Crepe myrtles bloom on new wood. This means that flowers form on the current season's growth, making late winter or early spring pruning the perfect time to encourage fresh, new branches that will burst into bloom in the summer.
Tools & Safety Considerations
Before you start pruning, make sure you have the right tools. Keep them sharp and clean — dull blades can tear the bark, causing slow-healing wounds that attract pests and disease.
Hand Pruners
For small, thin branches under ¼ inch in diameter.
Loppers
For medium branches up to 1½ inches in diameter.
Pruning Saw
For thicker branches that loppers cannot handle.
Gloves & Safety Glasses
Protect your hands and eyes from scratches and debris.
Step-by-Step Crepe Myrtle Pruning Guide
1. Remove Dead, Diseased, or Damaged Wood
Start by cutting out dead or broken branches. Dead wood is often brittle, gray, or cracked, while diseased branches may show discoloration or fungal growth.
2. Eliminate Crossing or Rubbing Branches
Branches that cross and rub against each other can create open wounds, inviting disease and pests. Remove the weaker or less well-placed branch.
3. Remove Suckers & Root Sprouts
Thin shoots often sprout at the base of the tree. Cut them at soil level to prevent energy from being wasted on unnecessary growth.
4. Shape the Canopy — Keep It Natural!
NEVER top a crepe myrtle (a practice called "crepe murder"). This weakens the tree, causes unsightly growth, and leads to fewer flowers. Instead, thin out crowded areas by selectively removing small branches, allowing sunlight and air to penetrate the canopy.
5. Make Clean, Precise Cuts
Always cut just above a bud facing outward or just outside the branch collar — the swollen area where a branch meets another branch or the trunk.
6. Step Back & Assess
Pruning is an art as much as a science. Step back frequently to ensure the tree maintains a balanced, natural shape.
After-Pruning Care
Tulsa's spring weather can be unpredictable, but crepe myrtles are hardy. No special treatment is needed after pruning. Follow these tips for best results:
Fertilize
Apply a slow-release fertilizer in early spring to support new growth.
Water Deeply
Ensure the tree gets deep but infrequent watering during dry spells.
Mulch the Base
Mulch around the base to retain moisture and suppress weeds.
