How To Get Rid Of Overgrown Blackberry Bushes

Getting rid of overgrown blackberry bushes takes patience, persistence, and a solid plan.
 
If you’ve ever stared at a tangled thicket taking over your yard, you know exactly how intimidating these plants can be.
 
Blackberry bushes spread aggressively through underground runners and sprawling canes, so simply yanking at them won’t solve the problem.
 
But the good news is that you can absolutely get rid of overgrown blackberry bushes with the right approach.
 
In this post, we’ll walk through proven methods to remove blackberry bushes for good and keep them from coming back.
 
Let’s dig in.
 

Why Getting Rid of Overgrown Blackberry Bushes Is So Tough

Getting rid of overgrown blackberry bushes is tough because these plants are built to survive.
 
Here’s why they’re such a challenge:
 

1. They Spread Through Underground Roots

Blackberry bushes send out creeping root systems that travel far beneath the soil.
 
You can cut every cane to the ground and still find new shoots popping up weeks later.
 
If you don’t remove the roots, the bushes will keep coming back stronger.
 

2. Their Canes Root Wherever They Touch

The long, arching canes of blackberry bushes tip over and root into the soil when they touch the ground.
 
That means one plant can turn into a whole thicket in a single season.
 
This is why overgrown blackberry bushes spread so fast if left unchecked.
 

3. Those Thorns Fight Back

Anyone who’s tried clearing blackberry bushes knows the scratches and snags all too well.
 
The thorns make manual removal slow and painful, which is part of why the job gets put off.
 
Heavy gloves and long sleeves are non-negotiable when you tackle this.
 

How to Get Rid of Overgrown Blackberry Bushes Step by Step

Here’s a practical plan for getting rid of overgrown blackberry bushes in your yard.
 

1. Cut the Canes Down First

Start by cutting all the canes down to ground level using loppers or a brush cutter.
 
This clears the tangle and gives you a safe working space to reach the roots.
 
Bag up the cuttings and dispose of them rather than leaving them on the ground.
 

2. Dig Out the Root Ball and Runners

Once the top growth is gone, dig out the root ball and any thick roots you can find.
 
A mattock or digging fork works well for getting underneath the crown of the plant.
 
Follow the runners outward and pull them up as far as they go.
 

3. Smother the Area With Mulch or Cardboard

After removing the bulk of the plant, cover the area with cardboard and a thick layer of mulch.
 
This blocks light and stops any leftover root fragments from sprouting.
 
Leave the covering in place for several months for the best results.
 

4. Use Herbicide as a Last Resort

If the blackberry bushes keep returning, a targeted herbicide can help finish the job.
 
Apply it to fresh cuts on the remaining stumps so it travels down into the roots.
 
Always follow the label directions and check local regulations before you spray.
 

Tips to Keep Blackberry Bushes From Coming Back

Staying ahead of regrowth is the secret to winning the battle for good.
 
Keep these habits in mind after you’ve cleared the main thicket.
 

1. Patrol for New Shoots Regularly

Walk the area every couple of weeks and pull any new shoots while they’re small.
 
Catching them early is far easier than waiting for another thicket to form.
 

2. Mow or Cut Around the Edges

Regular mowing around the perimeter keeps blackberry bushes from creeping back in.
 
A sharp string trimmer can also knock down stray canes before they root.
 

3. Replant the Space With Something Else

Planting grass, shrubs, or ground cover in the cleared spot makes it harder for blackberries to return.
 
These plants compete for light and space, which keeps the invaders at bay.
 

4. Dispose of Cuttings Properly

Never toss blackberry cuttings onto a compost pile or bare ground.
 
Those canes and roots can re-root and start a brand new patch.
 
Bag them up and take them to your local green waste facility instead.
 

So, How Do You Get Rid of Overgrown Blackberry Bushes?

Getting rid of overgrown blackberry bushes comes down to cutting, digging, smothering, and staying consistent.
 
You can get rid of overgrown blackberry bushes by removing the canes and roots, then blocking regrowth with mulch or a targeted herbicide.
 
The key is to keep at it, because blackberry bushes will test your patience.
 
Do a little each week, wear thick gloves, and protect your skin from the thorns.
 
With steady effort, you can reclaim your yard and enjoy a space free of those stubborn overgrown blackberry bushes for good.
