How Do You Get Rid Of Blackberry Bushes

You can get rid of blackberry bushes by cutting them down, digging up the roots, and staying consistent with follow-up treatments until they stop coming back.
 
Blackberry bushes are stubborn, and if you’ve ever tried to get rid of blackberry bushes, you know they don’t go down without a fight.
 
These thorny invaders spread through deep root systems and seeds, so getting rid of blackberry bushes takes patience, the right tools, and a solid plan.
 
In this post, we’ll walk through how to get rid of blackberry bushes step by step, including natural methods, chemical options, and tips to keep them from returning.
 
Let’s dig in.
 

Why Blackberry Bushes Are So Hard to Get Rid Of

Getting rid of blackberry bushes is tough because these plants are built to survive.
 
Here’s why they keep coming back:
 

1. They Have Deep, Aggressive Root Systems

Blackberry bushes send out underground runners called rhizomes that can spread several feet in every direction.
 
If you only cut the visible canes, the roots stay alive and send up new shoots within weeks.
 
That’s why getting rid of blackberry bushes means attacking the roots, not just the top growth.
 

2. They Regrow From Tiny Root Fragments

Even a small piece of root left in the soil can sprout a brand-new blackberry bush.
 
This is why digging must be thorough, and why tilling the soil can sometimes make the problem worse.
 

3. The Thorns Make Removal Miserable

Those sharp thorns aren’t just painful, they slow you down and make you avoid the job.
 
That delay gives the blackberry bushes time to spread even further.
 

How to Get Rid of Blackberry Bushes Naturally

If you prefer to get rid of blackberry bushes without chemicals, you absolutely can.
 
It just takes more time and muscle.
 

1. Cut the Canes Down First

Start by cutting all the canes down to the ground using loppers or a brush cutter.
 
Wear thick gloves, long sleeves, and eye protection because blackberry thorns can scratch and poke through light clothing.
 

2. Dig Out the Roots Completely

After cutting, use a shovel or mattock to dig up the root ball and as many rhizomes as you can find.
 
Sift through the soil with your hands or a rake to remove every root fragment you can see.
 
This is the most important step when getting rid of blackberry bushes naturally.
 

3. Smother the Area With Mulch or Cardboard

Cover the cleared ground with a thick layer of cardboard, then top it with wood chips or mulch.
 
This blocks sunlight and stops any leftover roots from sending up new shoots.
 
Leave the covering in place for at least one full growing season to starve the roots.
 

4. Mow New Shoots Relentlessly

Every time new blackberry shoots pop up, mow them down before they can grow leaves.
 
Without leaves, the roots can’t make food, and eventually, they die.
 
This method of getting rid of blackberry bushes works best if you stay on top of it every week or two.
 

Using Herbicides to Get Rid of Blackberry Bushes

When natural methods aren’t enough, herbicides can help you get rid of blackberry bushes faster.
 

1. Choose the Right Herbicide

Look for products containing glyphosate or triclopyr, which are effective against blackberry bushes.
 
Always follow the label instructions carefully, and check your local rules before spraying.
 

2. Cut and Paint the Stumps

Cut the canes down to the ground and immediately paint the cut ends with undiluted herbicide.
 
This method, called cut-and-paint, sends the chemical straight into the roots.
 

3. Spray New Growth

For large patches, you can spray the leaves of actively growing blackberry bushes.
 
Spray on a calm, dry day when rain isn’t expected for at least 24 hours.
 

4. Repeat Treatments Are Essential

One application rarely does the job, so plan to retreat any regrowth for two or three seasons.
 
Getting rid of blackberry bushes with herbicides takes persistence, but it works.
 

Tips to Keep Blackberry Bushes From Coming Back

Once you’ve done the hard work of getting rid of blackberry bushes, don’t let them sneak back in.
 

1. Monitor the Area Regularly

Walk the cleared spot every few weeks and pull or cut any new shoots immediately.
 

2. Plant Competitively

Plant fast-growing grasses or ground covers that outcompete blackberry seedlings for light and water.
 

3. Clean Your Tools

Wash your shovel, loppers, and mower blades after working in a blackberry patch so you don’t spread root fragments elsewhere.
 

4. Deal With Neighboring Plants

If blackberry bushes are growing on a nearby property, talk to your neighbor about a joint removal plan.
 
Otherwise, their plants will keep seeding your side.
 

So, How Do You Get Rid of Blackberry Bushes?

Getting rid of blackberry bushes comes down to cutting, digging, smothering, and repeating until the roots finally give up.
 
Whether you choose natural methods or herbicides, consistency matters more than speed.
 
Stay persistent, protect yourself from the thorns, and don’t get discouraged if they pop back up once or twice.
 
With time and effort, getting rid of blackberry bushes is completely doable, and your yard will thank you for it.
