How To Remove Crepe Myrtle Roots

To remove crepe myrtle roots, you’ll need a combination of digging, cutting, and sometimes chemical treatment depending on how large and established the root system has become.
 
Crepe myrtle roots are notoriously tough and fibrous, and they don’t give up easily once they’ve anchored themselves into your yard.
 
Whether you’re dealing with a stump that’s been cut down or you want to remove crepe myrtle roots before they damage your driveway or foundation, this guide will walk you through every method step by step.
 
We’ll cover manual removal, grinding, chemical options, and natural alternatives so you can pick the best approach for your situation.
 
Let’s dig in and get those stubborn roots out of your landscape for good.
 

Why Removing Crepe Myrtle Roots Is So Challenging

Crepe myrtle roots are shallow but they spread wide, often extending two to three times the width of the tree’s canopy.
 
This means the root system can be massive even if the trunk is relatively small, which is why so many homeowners struggle with this task.
 
These roots also produce suckers, which are new shoots that pop up from the remaining root fragments and keep the problem alive for years.
 
If you only cut the trunk and leave the roots, you’ll likely see new growth sprouting within weeks, making it crucial to remove crepe myrtle roots completely.
 
Another challenge is that the wood is dense and interwoven, so it dulls saw blades and breaks shovel handles if you’re not careful.
 
Understanding these obstacles helps you prepare the right tools and mindset before you start.
 

1. The Root System Structure

Crepe myrtle roots don’t grow deep like oak or pine trees, instead they form a dense mat of fibrous roots near the surface.
 
This mat can be two to three feet deep at the most, but it spreads horizontally up to 20 feet or more from the base.
 
Because the roots are so shallow, they often heave sidewalks and crack patios as they thicken over time.
 
Knowing this layout helps you plan where to dig and where to focus your removal efforts.
 

2. Why Suckers Keep Coming Back

When you cut down a crepe myrtle, the roots don’t immediately die because they still have stored energy and nutrients.
 
This stored energy triggers the root system to send up suckers, which are essentially new trees trying to regenerate.
 
These suckers can appear up to 30 feet away from the original stump, making it feel like a never-ending battle.
 
To truly remove crepe myrtle roots, you have to either physically extract every piece or kill the root system so it can’t produce new growth.
 

Best Methods to Remove Crepe Myrtle Roots

There are several proven ways to remove crepe myrtle roots, and the right one depends on your budget, physical strength, and how fast you need the job done.
 
Here are the most effective approaches, ranked from simplest to most aggressive.
 

1. Manual Digging and Pulling

Manual removal is the most straightforward way to remove crepe myrtle roots, and it works best for small to medium-sized trees.
 
Start by using a sharp shovel or spade to cut a circle around the stump, about two to three feet away from the base.
 
Then, use a pickaxe or mattock to break up the soil and expose the major lateral roots that branch outward.
 
Cut these roots with a root saw or loppers and then work your way toward the central root ball.
 
Once you’ve exposed the main root ball, you can use a pry bar or come-along winch to lever it out of the ground.
 
This method requires serious elbow grease, but it’s chemical-free and leaves no toxic residue in your soil.
 
Be prepared to spend several hours on this, and enlist a friend if the stump is large.
 

2. Stump Grinding

If manual digging seems overwhelming, a stump grinder can remove crepe myrtle roots much faster by shredding the wood into mulch.
 
You can rent a stump grinder from most home improvement stores for around $100 to $200 per day, or hire a professional to do it for you.
 
The grinder’s rotating blade chews through the stump and the top six to twelve inches of the root system.
 
Keep in mind that grinding doesn’t remove the deeper or wider roots, so suckers may still pop up in the surrounding area.
 
To prevent this, you’ll need to follow up by digging out any remaining large roots you can find after grinding.
 
Grinding is a great middle-ground option that saves your back while still making major progress.
 

3. Chemical Herbicide Application

For a more hands-off approach, you can kill the roots with a herbicide containing glyphosate or triclopyr.
 
The most effective way to apply this is right after cutting the tree down, because the fresh cut surface is still open and can absorb the chemical.
 
Drill several holes into the top of the stump and pour the herbicide directly into them, then cover the stump with a tarp to keep rain from washing it away.
 
Within a few weeks, the herbicide moves down into the root system and kills it from the inside out.
 
After the roots are dead, you can dig them out with much less effort because they’ll be brittle and dry.
 
This method is very effective, but you should use caution if you have pets or children playing in the yard, and always follow the label instructions.
 

4. Natural Decomposition with Epsom Salt

If you’d rather avoid harsh chemicals, Epsom salt is a natural alternative that can help remove crepe myrtle roots over time.
 
Drill holes into the freshly cut stump and pack them with plain Epsom salt, then add a little water to help it dissolve.
 
Cover the stump with a trash bag to keep it moist and let nature do the work.
 
The salt draws moisture out of the wood and speeds up decomposition, making the roots easier to break apart in a few months.
 
This is a much slower process than herbicide, so it’s best if you’re not in a hurry.
 
You’ll still need to dig out the softened root mass eventually, but it will be far less work.
 

Preventing Crepe Myrtle Roots from Regrowing

Once you remove crepe myrtle roots, you need to make sure they don’t make a comeback and ruin all your hard work.
 
The first thing to do is remove every visible root fragment from the soil, because even a small piece can regenerate.
 
If you find suckers emerging after your removal efforts, cut them down and immediately apply a stump killer to the cut surface.
 
You can also lay down a thick layer of landscape fabric or plastic sheeting over the area to block sunlight and smother any remaining root activity.
 
Another effective trick is to plant a dense ground cover or lawn grass over the spot, which competes with the roots for water and nutrients.
 
Monitor the area for at least two full growing seasons, since crepe myrtle roots can surprise you by sending up shoots long after you thought they were gone.
 

So, How Do You Remove Crepe Myrtle Roots?

You can remove crepe myrtle roots by digging them out manually, grinding the stump, applying herbicide, or using natural decomposition methods.
 
The best choice depends on the size of the tree, your physical ability, and your willingness to wait for results.
 
For small trees, grab a shovel and a pickaxe and commit to a few hours of hard work.
 
For larger specimens, rent a stump grinder or call in a professional arborist to save your time and energy.
 
And if you want the least effort, chemical treatment will kill the roots so you can dig them out later with ease.
 
Whichever path you choose, remember to stay vigilant about suckers and be patient through the process.
 
Now that you know exactly how to remove crepe myrtle roots, you can reclaim your yard and plant something new in that spot without worry.
 
Good luck, and happy gardening.
