How To Permanently Get Rid Of Blackberry Bushes

You can permanently get rid of blackberry bushes, but it takes patience and persistence because these plants are stubborn survivors.
 
If you’ve ever battled a blackberry patch, you know how quickly it can take over a garden, fence line, or entire yard.
 
The good news is that permanently getting rid of blackberry bushes is absolutely possible when you combine the right timing, tools, and techniques.
 
In this post, we’ll walk through how to permanently get rid of blackberry bushes, why they keep coming back, and the methods that actually work for good.
 
Let’s dig in.
 

Why Blackberry Bushes Keep Coming Back

Getting rid of blackberry bushes permanently starts with understanding why they’re so hard to kill.
 
These plants have a few sneaky survival tricks up their sleeves.
 

1. Their Roots Spread Underground

Blackberry bushes send out creeping roots and rhizomes that travel far beneath the soil.
 
Even if you chop the visible plant down to the ground, those underground runners keep feeding new shoots.
 
That’s why simply mowing or cutting blackberry bushes rarely works on its own.
 

2. They Root Where Canes Touch Soil

When blackberry canes bend over and touch the ground, they can root right there and start a brand new plant.
 
This means a single bush can quietly turn into a whole thicket if you’re not paying attention.
 

3. Seeds Stay Viable for Years

Birds and animals drop blackberry seeds everywhere, and those seeds can sit dormant in the soil for years.
 
So even after you remove the bushes, new seedlings can pop up later and restart the cycle.
 

How to Permanently Get Rid of Blackberry Bushes

Permanently removing blackberry bushes means attacking both the top growth and the root system.
 
Here are the most effective approaches.
 

1. Cut Them Down at the Right Time

The best time to cut blackberry bushes is in late summer or early fall, when the plant is storing energy in its roots.
 
Cut the canes down to the ground using loppers, a brush cutter, or a mower for large patches.
 
This weakens the plant and sets it up for the next step.
 

2. Dig Out the Roots and Rhizomes

For smaller patches, digging is one of the most reliable ways to get rid of blackberry bushes permanently.
 
Use a mattock, shovel, or pitchfork to loosen the soil and pull out as much of the root system as you can.
 
Any root pieces left behind can sprout again, so sift through the soil carefully.
 

3. Apply Herbicide to Fresh Cuts

For larger infestations, treating freshly cut stumps with a systemic herbicide like glyphosate or triclopyr works well.
 
Apply it directly to the cut surface within minutes of cutting so it travels down into the roots.
 
This method is one of the most effective ways of killing blackberry bushes at the root.
 

4. Smother the Area with Mulch or Tarp

After cutting and digging, cover the ground with a thick black tarp or several inches of heavy mulch.
 
Blocking sunlight starves any remaining roots and stops new shoots from growing.
 
Leave the cover in place for at least one full growing season for the best results.
 

5. Mow Consistently to Exhaust the Plant

If you’re dealing with a big patch, regular mowing can eventually exhaust blackberry bushes.
 
Mow every time new growth reaches a few inches tall, never letting the canes build up energy.
 
Combined with other methods, consistent mowing helps you get rid of blackberry bushes for good.
 

Common Mistakes When Removing Blackberry Bushes

A lot of people fail to permanently get rid of blackberry bushes because of a few easy-to-make mistakes.
 

1. Only Cutting the Tops

Cutting blackberry bushes without touching the roots just makes them come back stronger.
 

2. Leaving Canes on the Ground

Blackberry canes left lying around can root and start new plants, so bag them up and toss them out.
 

3. Giving Up Too Soon

Getting rid of blackberry bushes permanently takes follow-up, so plan to check the area for regrowth for months.
 

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

You can permanently get rid of blackberry bushes by combining cutting, digging, herbicide, smothering, and consistent follow-up.
 
It’s not a one-and-done job, but with persistence, you can absolutely kill blackberry bushes for good.
 
Stay consistent, monitor the area, and don’t let new shoots get a foothold.
