Yes, crepe myrtles can be kept small with the right pruning techniques and variety choices.
If you’ve been wondering whether you can keep crepe myrtles small, the answer is a confident yes, and it’s easier than you might think.
Keeping crepe myrtles small isn’t about harsh topping or butchering the tree, it’s about smart, consistent care from the start.
You can keep crepe myrtles small by selecting dwarf varieties, pruning annually, and using proper methods that maintain their natural beauty.
In this post, we’ll explore exactly how to keep crepe myrtles small, the best techniques to manage their size, and common mistakes to avoid.
Let’s dig into the details so your crepe myrtles stay compact and stunning for years.
How to Keep Crepe Myrtles Small
Keeping crepe myrtles small starts with understanding their growth habits and working with them, not against them.
You can keep crepe myrtles small through a combination of variety selection, strategic pruning, and container planting.
Here’s how it all comes together to help you maintain a smaller, more manageable crepe myrtle in your landscape.
1. Choose Dwarf or Miniature Varieties
The single most effective way to keep crepe myrtles small is to start with a variety that naturally grows small.
Dwarf crepe myrtles typically reach only 3 to 6 feet tall, while miniature types stay under 3 feet.
Some popular dwarf options include ‘Pocomoke,’ ‘Chickasaw,’ and ‘Centennial,’ all bred specifically for compact growth.
If you choose a standard crepe myrtle that grows 20 to 30 feet, no amount of pruning will truly keep it small, it’ll just look sad and stressed.
So, to keep crepe myrtles small from the get-go, always check the mature height on the plant tag before buying.
2. Prune in Late Winter or Early Spring
Pruning is your best friend when you want to keep crepe myrtles small, but timing is everything.
The ideal window is late winter or early spring, just before new growth begins.
During this dormant period, you can see the branch structure clearly and make precise cuts.
To keep crepe myrtles small, remove suckers at the base, thin out crossing branches, and cut back last year’s growth by about one-third.
This encourages fresh, vigorous shoots while keeping the overall height in check.
Never prune in late summer or fall, as this stimulates tender new growth that can be damaged by winter cold.
3. Use the Three-Branch or Crape Murder-Free Method
When pruning to keep crepe myrtles small, avoid the dreaded “crape murder” technique of topping.
Topping means cutting large branches back to ugly stubs, which ruins the tree’s shape and promotes weak, spindly regrowth.
Instead, use a selective thinning method where you remove entire branches back to the trunk or a main leader.
For a multi-stemmed small tree, choose three to five main trunks and remove the rest.
This keeps the crepe myrtle small in height while preserving its elegant, vase-shaped form.
The result is a healthier plant that stays compact without looking butchered.
4. Plant in Containers for Ultimate Size Control
If you really want to keep crepe myrtles small, growing them in pots is a game-changer.
Container-grown crepe myrtles naturally stay smaller because their roots are confined.
Root restriction limits top growth, so even a standard variety will stay much shorter than it would in the ground.
Choose a pot that’s at least 16 to 20 inches in diameter and use well-draining potting soil.
You’ll still need to prune to keep crepe myrtles small and tidy, but container life does much of the heavy lifting for you.
Plus, you can move the pot around to find the perfect sunny spot, which helps with blooming too.
Other Ways to Control Crepe Myrtle Size
Beyond the basics, there are a few extra tricks to keep crepe myrtles small and well-behaved.
These methods are simple but effective, especially when combined with the pruning and planting tips above.
1. Limit Fertilizer
Fertilizer encourages vigorous growth, so go easy if you want to keep crepe myrtles small.
Skip high-nitrogen fertilizers, as they push out lots of leafy growth and tall shoots.
Instead, use a low-nitrogen, slow-release fertilizer formulated for flowering shrubs.
Apply it sparingly in early spring, and your crepe myrtle will focus on blooming rather than getting taller.
This simple tweak helps you keep crepe myrtles small without sacrificing those beautiful summer flowers.
2. Pinch Back New Growth in Summer
During the growing season, you can keep crepe myrtles small by pinching or lightly trimming new shoots.
When new branches reach about 12 inches long, pinch off the tips with your fingers or pruners.
This encourages branching lower down and prevents the plant from shooting upward too fast.
Do this every few weeks from late spring to midsummer, and you’ll maintain a compact, bushy shape.
Just stop pinching by late July so flower buds can form for the next bloom cycle.
3. Mulch and Water Wisely
Healthy crepe myrtles are easier to keep small because they don’t stress-grow.
Apply 2 to 3 inches of mulch around the base, but keep it a few inches away from the trunk.
Mulch conserves moisture, regulates soil temperature, and reduces weeds that compete for nutrients.
Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
Overwatering can lead to rapid, leggy growth, which makes it harder to keep crepe myrtles small and neat.
Common Mistakes When Trying to Keep Crepe Myrtles Small
Even with good intentions, many gardeners make errors that backfire when trying to keep crepe myrtles small.
Avoiding these pitfalls will save you time and keep your plant healthy and compact.
1. Topping the Tree
Topping is the worst mistake you can make when you want to keep crepe myrtles small.
It creates ugly knobs, weak regrowth, and can even shorten the tree’s lifespan.
The new shoots that sprout are tightly clustered and prone to breakage during storms.
Plus, topping often results in more flowers, but they’re on weak stems that flop over.
Always prune selectively instead of topping to keep crepe myrtles small and beautiful.
2. Pruning Too Late in the Season
Pruning in late summer or fall is another common error.
This stimulates new growth that won’t harden off before frost, leading to winter dieback.
And if you prune too late, you’ll cut off developing flower buds and reduce next year’s blooms.
Stick to late winter or early spring pruning to keep crepe myrtles small without harming their flowering potential.
3. Ignoring Suckers and Water Sprouts
Suckers at the base and water sprouts along the trunk can quickly make a crepe myrtle look messy and tall.
These fast-growing shoots steal energy from the main plant and add unnecessary height.
Remove them regularly, cutting as close to the base or branch as possible.
If you stay on top of this, you’ll find it much easier to keep crepe myrtles small and clean.
So, Can Crepe Myrtles Be Kept Small?
Yes, crepe myrtles can be kept small, and it’s completely doable for any gardener.
You can keep crepe myrtles small by picking dwarf varieties, pruning correctly in late winter, and using containers if needed.
Limiting fertilizer, pinching new growth, and avoiding topping will also help you maintain that compact size.
Remember, the goal isn’t to fight the plant’s natural beauty, it’s to guide it into a smaller, more manageable form.
So, can crepe myrtles be kept small? Absolutely, with a little patience and the right techniques, you’ll enjoy a tidy, blooming crepe myrtle that fits perfectly in your yard.
Happy gardening, and here’s to keeping your crepe myrtles small and spectacular all season long.
