When and How to Prune Crepe Myrtles for Maximum Blooms

Few things say “southern summer” like a crepe myrtle in full, vibrant bloom. These flowering trees are beloved for their long-lasting color, unique bark, and graceful canopy shape. But to enjoy their full potential, you’ll want to give them a little seasonal attention.

If you’ve ever been unsure about when or how to prune a crepe myrtle, you're not alone. The good news? It’s easier than you think. With a few simple guidelines, you can keep your tree healthy and blooming beautifully year after year, without committing the dreaded “crepe murder.”

Why Prune Crepe Myrtles?

Pruning isn’t just about appearance. It helps your crepe myrtle develop strong branches, maintain a balanced structure, and produce even more flowers. The right pruning also improves airflow and sunlight penetration, reducing the risk of pests and disease.

The goal is to shape the tree in a way that encourages fresh growth, and that’s exactly where the blooms will appear.

When to Prune

Timing matters! Crepe myrtles bloom on new growth, so pruning at the right moment helps set the stage for a spectacular summer display.

Best time to prune:
Late winter to early spring, usually February through early March in eastern Virginia. You’ll want to wait until the threat of hard frost has passed. Pruning too early can expose the plant to cold damage, while pruning too late could reduce your flower show.

Avoid pruning in summer (when the tree is actively blooming) or fall (when new growth may not survive winter temperatures).

So why are we telling you this in a July blog?
Because that’s when your crepe myrtle is putting on its biggest show and it’s also usually when people start to notice things they wish they had pruned. Whether it’s suckers at the base, awkward branches, or an overall shape that’s off, now is the time you're most likely to spot it. While you don’t want to prune mid-bloom, it’s the perfect time to take mental notes and prepare for a successful prune next season. So make sure to save this blog for when you are getting ready for spring!

How to Prune for Maximum Blooms

Pruning doesn’t need to be drastic, in fact, less is often more. Here's a step-by-step guide to help you prune with purpose:

Step 1: Take a Step Back

Start by looking at the overall shape of the tree. A well-pruned crepe myrtle has a vase-like form with upward-reaching limbs and an open center.

Step 2: Remove the Three D’s

Get rid of any wood that is:

  • Dead
  • Diseased
  • Damaged

This not only cleans up the tree’s appearance but also improves its overall health.

Step 3: Open the Interior

Thin out smaller branches and shoots growing toward the center of the tree. This helps sunlight and air move freely through the canopy, which promotes better blooms and reduces the risk of mildew.

Step 4: Shape the Canopy

Lightly thin the top of the tree by removing crowded or crossing branches. Always cut just above a bud that’s facing in the direction you want new growth to go. Keep in mind the tree’s natural shape, resist the urge to force it into something it’s not.

What Not to Do: Avoid “Crepe Murder”

One of the most common mistakes people make is severely topping their crepe myrtles or cutting them back to bare stubs each year. While this might seem like a shortcut to control size or encourage blooms, it often leads to:

  • Weak, spindly growth
  • Fewer flowers
  • Unsightly knobby growth at the cut sites

Instead, aim for gentle shaping and thoughtful thinning. You’ll get stronger growth and more natural beauty in return.

Extra Tips for Success

  • Always use sharp, clean tools to make smooth cuts and prevent disease.
  • Take your time, pruning is both a science and an art.
  • Know your variety. Dwarf crepe myrtles need minimal shaping, while larger varieties benefit from more structure.

Crepe myrtles thrive with a little love in late winter. A light, careful pruning routine can set the stage for months of vibrant color and graceful form. Skip the severe cuts and focus on shaping and health, your tree will reward you with bold blooms all summer long. Need help identifying your variety or want expert advice on shaping a specific plant?
