How To Permanently Get Rid Of Blackberry Bushes

You can permanently get rid of blackberry bushes, but it takes patience and a solid plan.
 
Blackberry bushes are aggressive growers, and their underground root systems can spread for years if you don’t remove them completely.
 
If you’ve been wondering how to permanently get rid of blackberry bushes without them creeping back season after season, you’re in the right place.
 
The good news is that with the right combination of cutting, digging, and smothering, you can eliminate blackberry bushes for good.
 
In this post, we’ll walk through the most effective ways to get rid of blackberry bushes permanently, plus the mistakes that let them grow back.
 
Let’s dig in.
 

Why Blackberry Bushes Keep Coming Back

Blackberry bushes are tough to kill because they don’t rely on just one way to survive.
 
Understanding why they keep returning is the first step in getting rid of blackberry bushes permanently.
 

1. They Spread Through Underground Roots

The biggest reason blackberry bushes resurface is their sprawling root system.
 
Those roots send up new shoots from deep underground, even after you’ve cut everything above the soil.
 
That’s why simply mowing or chopping blackberry bushes rarely works long-term.
 

2. They Root From Touching Canes

Blackberry canes that bend over and touch the ground can root themselves into new plants.
 
This means a single neglected cane can turn into a whole new patch of blackberry bushes.
 
This tip-rooting habit is why blackberry bushes seem to multiply overnight.
 

3. Seeds Stay Viable in Soil

Even if you remove every root, seeds left behind in the soil can sprout years later.
 
Birds and animals drop blackberry seeds too, so new bushes can appear even after you clear an area.
 
That’s why getting rid of blackberry bushes permanently means staying on top of the spot for a while.
 

How to Permanently Get Rid of Blackberry Bushes

The most reliable approach combines several methods rather than relying on just one.
 
Here’s how to permanently get rid of blackberry bushes step by step.
 

1. Cut the Canes Down First

Start by cutting blackberry bushes down to the ground using loppers or a brush cutter.
 
Wear thick gloves and long sleeves, since blackberry thorns can tear through skin easily.
 
Cutting the canes back makes the root system easier to reach and weakens the plant’s energy supply.
 

2. Dig Out the Root Crown

After cutting, dig out the root crown and as much of the root system as you can.
 
A mattock or pickaxe works well for prying up the thick, woody roots of blackberry bushes.
 
Getting rid of blackberry bushes permanently depends heavily on removing this crown, since that’s the plant’s engine.
 

3. Smother the Area With Cardboard or Tarp

Once the roots are gone, cover the ground with thick cardboard or a black landscape tarp.
 
Smothering blocks sunlight and stops any leftover roots from sending up new growth.
 
Leave the covering in place for at least one full growing season to starve out the blackberry bushes.
 

4. Use Herbicide as a Last Resort

If blackberry bushes keep returning, you can apply a systemic herbicide to the freshly cut stems.
 
This method works best in late summer or early fall when the plant is pulling nutrients down into its roots.
 
Always follow label directions carefully, and keep herbicide away from wanted plants and waterways.
 

5. Repeat the Process Over Time

Getting rid of blackberry bushes permanently rarely happens in one attempt.
 
Check the area every few weeks and pull any new shoots while they’re still small.
 
Consistency is what finally kills blackberry bushes for good.
 

Common Mistakes That Let Blackberry Bushes Regrow

Even with good intentions, a few missteps can let blackberry bushes bounce right back.
 
Here’s what to avoid if you want to get rid of blackberry bushes permanently.
 

1. Only Cutting the Tops

Chopping blackberry bushes down without touching the roots just makes them angry.
 
The plant responds by sending up even more shoots from its underground network.
 
To truly kill blackberry bushes, you have to deal with what’s below the soil.
 

2. Leaving Root Fragments Behind

Any piece of root left in the ground can sprout into a new blackberry bush.
 
That’s why digging thoroughly matters more than cutting quickly.
 
Ridding your yard of blackberry bushes means being a little ruthless with the shovel.
 

3. Giving Up Too Soon

Blackberry bushes can regrow for a year or two after your first removal attempt.
 
Staying consistent with cutting, digging, and smothering is what tips the odds in your favor.
 
Patience is honestly the most underrated tool for getting rid of blackberry bushes permanently.
 

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

You can permanently get rid of blackberry bushes by cutting the canes, digging out the root crown, smothering the soil, and repeating the process until nothing grows back.
 
Blackberry bushes are persistent, but they’re not invincible, and a combination of methods will beat them over time.
 
Skip the shortcuts, stay consistent, and you’ll finally get rid of blackberry bushes for good.
