How To Get Rid Of Blackberry Bushes For Good

You can get rid of blackberry bushes for good by removing the entire root system, not just the visible canes.
 
Blackberry bushes are persistent because their roots store energy and can send up new shoots even after the top growth is gone.
 
If you’ve been asking how to get rid of blackberry bushes permanently, the answer starts with digging deep and staying consistent.
 
In this post, we’ll walk through the most effective ways to get rid of blackberry bushes for good, from manual removal to chemical control and long-term prevention.
 
Let’s dig in.
 

Why Blackberry Bushes Are So Hard to Get Rid Of

Blackberry bushes are tough to get rid of because they spread through roots, seeds, and canes that root at the tips.
 
Understanding why they keep coming back is the first step to getting rid of blackberry bushes for good.
 

1. Extensive Root System

Blackberry bushes have deep, woody roots that can survive for years underground.
 
When you cut the canes, the roots still have enough energy to push up new growth within weeks.
 
That’s why simply mowing or trimming won’t get rid of blackberry bushes permanently.
 

2. Seeds That Stay Viable

Birds and animals spread blackberry seeds, and those seeds can stay dormant in the soil for years.
 
Even if you kill the parent plant, new blackberry bushes can sprout from old seeds.
 
So getting rid of blackberry bushes for good means dealing with the seed bank too.
 

3. Tip Rooting and Suckering

Many blackberry varieties root wherever their canes touch the ground.
 
They also send up suckers from lateral roots, creating a thicket that keeps expanding.
 
If you leave any root fragments behind, those fragments will grow into new blackberry bushes.
 

How to Get Rid of Blackberry Bushes for Good

Here are the methods that actually work when you want to get rid of blackberry bushes permanently.
 

1. Dig Out the Roots by Hand

The most reliable way to get rid of blackberry bushes for good is to dig out the entire root ball and as many lateral roots as you can.
 
Use a mattock, shovel, and pruning shears to cut canes back first.
 
Then loosen the soil around the base and pull the root crown out.
 
Follow every thick root you can see and remove it.
 
This method is labor-intensive but it’s the best way to get rid of blackberry bushes without chemicals.
 

2. Smother with Heavy Mulch or Black Plastic

If digging isn’t possible, smothering can help get rid of blackberry bushes over time.
 
Cut canes to the ground, then cover the area with thick black plastic or several layers of cardboard and mulch.
 
The lack of light and oxygen weakens the roots.
 
Leave it in place for at least one full growing season.
 
This method won’t get rid of blackberry bushes overnight, but it will kill most of them if you’re patient.
 

3. Use Herbicides Carefully

For large patches, herbicides can help get rid of blackberry bushes for good when applied correctly.
 
Use a brush-killer with triclopyr or glyphosate.
 
Cut the canes and paint the herbicide directly onto the freshly cut stems or leaves.
 
This systemic approach travels down to the roots and kills them.
 
Always follow label directions and avoid spraying desirable plants.
 

4. Repeat and Monitor

No matter which method you choose, you’ll need to repeat it.
 
Blackberry bushes will send up new shoots from missed roots or seeds.
 
Check the area every few weeks and remove any new growth immediately.
 
Consistency is the secret to getting rid of blackberry bushes for good.
 

5. Solarize the Soil

Solarization can help get rid of blackberry bushes and their seeds in hot, sunny climates.
 
Clear the area, water it, and cover with clear plastic sheeting for 4-6 weeks in summer.
 
The heat builds up and kills roots near the surface.
 
This works best as a follow-up after digging or smothering.
 

Preventing Blackberry Bushes from Coming Back

Once you’ve done the hard work, prevention keeps blackberry bushes from returning.
 

1. Maintain a Buffer Zone

Blackberry bushes spread from nearby wild areas.
 
Keep a mowed border around your garden or property to stop them from creeping in.
 

2. Plant Competitive Ground Cover

Dense, shade-forming plants can suppress blackberry seedlings.
 
Consider native grasses or robust ground covers that outcompete blackberry bushes.
 

3. Monitor After Disturbance

Any time you dig or disturb soil, blackberry seeds may germinate.
 
Watch the area closely for a year and pull any new blackberry bushes while they’re small.
 

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

You get rid of blackberry bushes for good by removing the entire root system and staying vigilant.
 
Whether you dig, smother, or use herbicides, the key is to attack the roots and repeat the process.
 
Blackberry bushes are persistent, but with patience and consistency, you can get rid of blackberry bushes permanently.
