How To Get Rid Of Walnut Trees

You can get rid of walnut trees by cutting them down, grinding the stump, and staying on top of regrowth for a few seasons.

 

But if you’ve ever dealt with these trees, you already know that getting rid of walnut trees isn’t quite that simple.

 

Black walnut trees, in particular, are notorious for their deep taproots, their stubborn stumps that refuse to die, and the juglone they release into the soil that can harm nearby plants.

 

Whether you’re dealing with a black walnut or a common walnut tree, the process of removing it takes patience and a solid plan.

 

In this post, we’ll walk through the best ways to get rid of walnut trees, from cutting and stump removal to dealing with suckers and saplings that keep coming back.

 

Let’s get into it.

 

Why Getting Rid of Walnut Trees Takes Real Effort

Getting rid of walnut trees is harder than removing most other trees, and there are a few reasons why:

 

1. They Have Deep, Stubborn Taproots

Walnut trees send down a strong taproot early in life, and that root goes deep.

 

That means you can’t just yank a walnut sapling out of the ground like you would a weed.

 

Even younger trees anchor themselves firmly, which makes physically removing walnut trees a real workout.

 

2. Their Stumps Resprout

Cutting down a walnut tree rarely kills it.

 

The stump and root system often stay alive and send up new shoots within weeks.

 

This is why so many people who try to get rid of walnut trees end up fighting the same tree for years.

 

3. Black Walnuts Release Juglone

Black walnut trees produce juglone, a chemical that can be toxic to certain plants, especially tomatoes, peppers, and azaleas.

 

That means when you’re getting rid of walnut trees, you’re not just removing a tree.

 

You’re also managing the soil it leaves behind if you plan to garden in that spot later.

 

How to Get Rid of Walnut Trees Safely

Here’s how to actually get rid of walnut trees for good:

 

1. Cut the Tree Down Properly

The first step in getting rid of walnut trees is cutting them down.

 

If the tree is large or close to structures, hire a certified arborist.

 

Walnut wood is heavy, and a falling trunk can do serious damage.

 

For smaller trees, cut close to the ground and leave a stump you can treat right away.

 

2. Kill the Stump With Herbicide

This is the most reliable way to get rid of walnut trees without endless resprouting.

 

Immediately after cutting, paint the fresh stump surface with a concentrated glyphosate or triclopyr herbicide.

 

The stump needs to be treated within minutes so the chemical absorbs before the wood seals itself.

 

This kills the root system and stops the stump from sending up new growth.

 

3. Grind the Stump

Once the stump is dead, you can grind it below the soil line.

 

Stump grinding removes the visible wood and makes the area safe for mowing or planting.

 

You can rent a stump grinder or hire a service, depending on the stump size.

 

4. Remove Suckers and Saplings by Hand

If you’re getting rid of walnut saplings or dealing with suckers from an old stump, pull them when the soil is soft after rain.

 

Grab the base of the stem and pull slowly to get as much root as possible.

 

For larger saplings, dig around the root and cut it below the soil line.

 

Persistent pulling weakens the root system over time.

 

5. Repeat for Several Seasons

Getting rid of walnut trees isn’t a one-and-done job.

 

Check the area every few weeks during the growing season and remove any new shoots immediately.

 

If you keep cutting regrowth before it can build up energy, the roots eventually starve and die.

 

Tips for Getting Rid of Walnut Trees Without Harming Other Plants

 

Be Careful With Herbicides

Apply herbicide directly to the stump with a brush instead of spraying, so you don’t hit nearby plants.

 

Watch the Soil After Removal

After getting rid of walnut trees, juglone can linger in the soil for a year or more.

 

Test the area or wait a season before planting sensitive vegetables.

 

Dispose of Walnut Debris Properly

Don’t leave walnut leaves, hulls, or wood chips in your garden beds.

 

Compost them separately or send them off-site.

 

So, How Do You Get Rid of Walnut Trees?

You can get rid of walnut trees by cutting them down, treating the stump with herbicide right away, grinding what’s left, and pulling up every sucker that appears until the roots die.

 

Getting rid of walnut trees takes patience because their roots fight back hard.

 

But with consistent effort over a season or two, you can clear the tree, reclaim your yard, and stop the regrowth for good.

 

Stay consistent, and you’ll finally win the battle against that stubborn walnut tree.
