How To Get Rid Of Blackberry Bushes For Good

Getting rid of blackberry bushes for good takes persistence, proper timing, and a combination of methods that exhaust the plant’s stubborn root system.
 
If you’ve been battling these thorny invaders and wondering how to get rid of blackberry bushes permanently, you’re not alone.
 
Blackberry bushes spread aggressively through underground rhizomes and seeds, so a single spray or cut won’t cut it.
 
The good news is that with the right approach, you can get rid of blackberry bushes for good and reclaim your garden or yard.
 
In this post, we’ll walk through how to get rid of blackberry bushes using proven methods, plus tips to stop them from coming back.
 
Let’s dig in.
 

Why Getting Rid of Blackberry Bushes Takes Real Effort

Getting rid of blackberry bushes is tough because these plants are built to survive.
 
Here’s why they keep coming back no matter what you do:
 

1. Blackberry Bushes Have Deep, Spreading Roots

The main reason it’s hard to get rid of blackberry bushes is their extensive root system.
 
Blackberry bushes send out rhizomes that creep underground and pop up new canes several feet away from the parent plant.
 
If you only pull the visible canes, the roots stay alive and send up fresh growth within weeks.
 
That’s why you have to target the roots if you truly want to get rid of blackberry bushes.
 

2. They Spread Through Seeds Too

Even if you kill the roots, blackberry bushes drop seeds that can stay viable in the soil for years.
 
Birds and animals also spread those seeds, which means new blackberry bushes can appear even after you’ve cleared an area.
 
So getting rid of blackberry bushes means dealing with both the current plants and the seed bank lurking below.
 

3. Canes Root Wherever They Touch Soil

Blackberry canes arch over and root at the tips when they touch the ground.
 
This tip-rooting habit lets a single blackberry bush turn into a thicket fast.
 
That’s another reason getting rid of blackberry bushes requires a thorough, repeated approach.
 

How to Get Rid of Blackberry Bushes for Good

Now let’s get into the methods that actually work when you want to get rid of blackberry bushes permanently.
 

1. Cut and Dig Out the Roots

Start by cutting all the canes down to the ground with loppers or a brush cutter.
 
Then dig out the root ball and as much of the rhizome network as you can.
 
This is the most hands-on way to get rid of blackberry bushes, but it works best for small patches.
 
Keep in mind that any root fragments left behind can regrow, so sift through the soil carefully.
 

2. Smother with Heavy Mulch or Black Plastic

If digging isn’t practical, smothering is an effective way to get rid of blackberry bushes.
 
Cut the canes down, then cover the area with thick black plastic or several layers of cardboard topped with mulch.
 
Blocking sunlight starves the roots and eventually kills the plant.
 
Leave the cover in place for at least one full growing season to get rid of blackberry bushes completely.
 

3. Use Herbicides Carefully

For large infestations, herbicides can help get rid of blackberry bushes when applied correctly.
 
Cut the canes and paint the freshly cut stems with a glyphosate or triclopyr-based product.
 
This sends the chemical straight to the roots, which is far more effective than spraying the leaves alone.
 
Always follow label directions and avoid spraying on windy days to protect nearby plants.
 

4. Mow Repeatedly to Exhaust the Plant

Regular mowing weakens blackberry bushes by forcing them to use up stored energy.
 
Mow new growth every couple of weeks during the growing season.
 
Over time, this consistent cutting helps get rid of blackberry bushes by draining their reserves.
 
It’s slow, but it’s a reliable method for larger areas where digging isn’t an option.
 

5. Combine Methods for Best Results

The fastest way to get rid of blackberry bushes is to combine techniques.
 
Cut, dig, smother, and spot-treat with herbicide as needed.
 
No single method works perfectly on its own, but together they’ll get rid of blackberry bushes for good.
 

How to Stop Blackberry Bushes from Coming Back

Once you’ve done the hard work, you’ll want to keep blackberry bushes from returning.
 
Here’s how to stay ahead of them:
 

1. Monitor the Area Regularly

Check the cleared spot every few weeks for new shoots.
 
Pulling sprouts early stops them from rebuilding the root system.
 
Staying vigilant is key if you want to get rid of blackberry bushes long-term.
 

2. Replant with Competitive Ground Cover

Planting dense ground cover or grass shades out blackberry seedlings.
 
This makes it harder for blackberry bushes to get established again.
 

3. Keep the Soil Covered

Mulch bare spots to block light and discourage seed germination.
 
Fewer seedlings mean less work keeping blackberry bushes away.
 

So, How Do You Get Rid of Blackberry Bushes for Good?

Getting rid of blackberry bushes for good means attacking both the canes and the roots with a mix of cutting, digging, smothering, and targeted herbicide.
 
It won’t happen overnight, but with consistency and a little patience, you can get rid of blackberry bushes permanently.
 
Stay on top of new growth, and you’ll finally win the battle against those stubborn blackberry bushes.
