How To Get Rid Of Blackberry Bushes Permanently

You can get rid of blackberry bushes permanently by digging out the entire root system, smothering the area, or using a targeted herbicide.
 
Getting rid of blackberry bushes permanently is one of those tasks that feels impossible while you’re in the middle of it.
 
Those thorny canes seem to come back stronger every time you cut them down.
 
But the good news is that blackberry bushes can be removed for good if you attack both the canes you see and the roots you don’t.
 
In this post, we’ll walk through how to get rid of blackberry bushes permanently, the methods that actually work, and the mistakes that let them sneak back into your garden.
 
Let’s dig in.
 

Why Blackberry Bushes Keep Coming Back

Blackberry bushes are stubborn survivors, and that’s the real reason they’re so hard to kill.
 
Before you can get rid of blackberry bushes permanently, you need to understand what you’re fighting.
 

1. They Spread Through Roots and Canes

Blackberry bushes send out underground stems called rhizomes, and those rhizomes can travel several feet in every direction.
 
Even a small piece of root left in the soil can push up a brand new cane.
 
On top of that, the tips of blackberry canes often root wherever they touch the ground.
 
That means a single plant can quietly become a whole thicket if you look away for one season.
 

2. They Store Energy Underground

Every time you cut a blackberry bush down to the ground, the root system stays alive and stocked with stored energy.
 
The plant simply spends that energy to grow new canes, often faster than before.
 
This is why chopping blackberry bushes without touching the roots rarely works.
 
You’re pruning, not killing.
 

3. Birds and Wildlife Replant Them

Birds love blackberries, and they drop seeds wherever they perch.
 
So even after you clear your land, new blackberry bushes can pop up from seeds carried in from nearby areas.
 
That’s why getting rid of blackberry bushes permanently often means staying vigilant for a season or two after the main removal.
 

How to Get Rid of Blackberry Bushes Permanently

Now let’s get into the methods that work to get rid of blackberry bushes permanently, from the physical to the chemical.
 

1. Dig Out the Roots Completely

The most reliable way to get rid of blackberry bushes permanently is to dig them out, roots and all.
 
Start by cutting the canes back so you can see what you’re dealing with.
 
Then use a shovel or mattock to loosen the soil around the base and pull up the root ball along with as many rhizomes as you can find.
 
This is hard work, and it’s best done when the soil is soft after rain.
 
The key is to remove every piece of root you can see, because even a two-inch fragment can regrow into a new blackberry bush.
 

2. Smother the Area With a Tarp

If digging isn’t an option, smothering is a solid way to get rid of blackberry bushes permanently over time.
 
Cut the canes down to the ground first, then cover the entire area with a heavy black tarp or thick layer of cardboard topped with mulch.
 
Block the sunlight completely, and the blackberry bushes can’t photosynthesize.
 
Leave the cover in place for at least one full growing season, sometimes two.
 
The roots eventually exhaust their stored energy and die.
 

3. Use a Targeted Herbicide

When you need to get rid of blackberry bushes permanently and other methods aren’t enough, a targeted herbicide can finish the job.
 
Choose a product labeled for blackberry or bramble control, and apply it to freshly cut canes or to the leaves while the plant is actively growing.
 
Always follow the label instructions and local regulations, and be careful not to spray desirable plants nearby.
 
Herbicides work best in late summer or early fall when the plant is pulling energy down into its roots.
 

4. Combine Cutting With Herbicide

The most effective strategy to get rid of blackberry bushes permanently is combining physical and chemical methods.
 
Cut the canes down to within a few inches of the soil, then immediately paint the cut stems with an herbicide.
 
This sends the chemical straight into the root system before the plant can seal itself off.
 
Repeat this process on any new growth that appears.
 
It usually takes two or three rounds, but it works.
 

5. Keep Mowing New Growth

Once the main bushes are gone, keep mowing or cutting any new blackberry shoots as soon as they appear.
 
Each time you cut a young cane, you drain a little more energy from the roots.
 
Over a season or two, the root system gives up completely.
 
This is the maintenance phase, and it’s what makes the removal permanent instead of temporary.
 

Common Mistakes to Avoid

Here are a few mistakes that keep people stuck fighting blackberry bushes forever.
 

1. Only Cutting the Tops

Cutting blackberry bushes without removing roots guarantees they’ll come back.
 

2. Leaving Root Fragments Behind

Every piece of root left in the soil is a future blackberry bush, so be thorough with your digging.
 

3. Giving Up Too Soon

Permanent removal takes time, and one pass is rarely enough.
 
Stay consistent, and the blackberry bushes won’t stand a chance.
 

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

You get rid of blackberry bushes permanently by removing the roots, smothering the area, or using a targeted herbicide, ideally combining these methods for the best results.
 
Blackberry bushes are tough, but they’re not invincible.
 
With patience and a plan, you can clear them from your yard for good.
