How To Get Rid Of Blackberries For Good

Getting rid of blackberries for good is possible, but it takes persistence because these plants are stubborn survivors.
 
You can get rid of blackberries by combining digging, cutting, smothering, and repeated follow-ups until the root system finally gives up.
 
If you’ve been asking how to get rid of blackberries for good, the honest answer is that it won’t happen with one weekend of work.
 
Blackberries spread through seeds, root crowns, and long underground runners, so getting rid of blackberries means attacking every part of the plant, not just the visible canes.
 
In this post, we’ll walk through how to get rid of blackberries for good using natural methods, chemical options, and smart timing so they don’t come back next spring.
 
Let’s dig in.
 

Why Getting Rid of Blackberries for Good Is So Hard

Getting rid of blackberries for good is hard because these plants are built to come back.
 
Here’s why they keep winning:
 

1. Deep, Aggressive Root Systems

Blackberry roots can travel several feet underground and send up new shoots from anywhere along the way.
 
If you only pull the top canes, the roots stay alive and simply push out fresh growth.
 

2. Canes That Root on Contact

When blackberry canes bend over and touch the soil, they root right there and start a brand new plant.
 
This is why a small patch can turn into a thicket in just one season.
 

3. Seeds That Wait Around

Birds drop blackberry seeds everywhere, and those seeds can sit dormant in the soil for years.
 
So even after you clear a patch, new blackberries may pop up from seeds you never planted.
 

How to Get Rid of Blackberries for Good Naturally

If you prefer to get rid of blackberries without harsh chemicals, these natural methods work well when you stay consistent.
 

1. Dig Out the Crown and Roots

The most direct way to get rid of blackberries for good is to dig out the root crown and as much of the runner system as you can.
 
Use a mattock, shovel, or digging fork to loosen the soil around the base.
 
Pull the crown out completely, then sift through the soil for any thick roots and remove those too.
 

2. Cut and Smother With Cardboard or Tarps

If digging isn’t practical, cut all canes to the ground and cover the area with heavy cardboard or a thick black tarp.
 
Weigh it down with rocks or mulch so no light gets through.
 
This smothering method starves the roots and can get rid of blackberries over several months.
 

3. Mow Relentlessly

For large patches, mowing every couple of weeks during the growing season will weaken blackberries over time.
 
Each time you cut new growth, the plant drains energy from its roots.
 
Keep it up and you’ll eventually get rid of blackberries by exhausting them.
 

4. Boiling Water and Vinegar Sprays

Pouring boiling water directly on young shoots can kill them, though it won’t reach deep roots.
 
Horticultural vinegar sprayed on fresh cuts can also help, but you’ll need repeat applications to get rid of blackberries this way.
 

Using Herbicides to Get Rid of Blackberries for Good

When natural methods aren’t enough, herbicides can help you get rid of blackberries, especially for large or stubborn infestations.
 

1. Cut-and-Paint Method

Cut canes down to the ground and immediately paint the cut ends with a concentrated glyphosate or triclopyr solution.
 
The plant pulls the herbicide down into the roots, killing the whole system.
 

2. Foliar Spraying

Spray actively growing blackberry leaves with a labeled brush-killer herbicide.
 
This works best in late summer or early fall when the plant is storing energy in its roots.
 

3. Follow Manufacturer Instructions

Always wear protective gear and follow the label exactly when using herbicides to get rid of blackberries.
 
Applying too much or at the wrong time can harm nearby plants and won’t speed up the process.
 

Staying Blackberry-Free After You Get Rid of Them

Even after you get rid of blackberries, you’ll need to stay vigilant for a while.
 

1. Monitor and Pull New Shoots

Walk the area every week or two and pull any new shoots while they’re small.
 
Catching them early prevents the roots from re-establishing.
 

2. Replant With Dense Ground Cover

Planting thick grass or a low-growing ground cover can crowd out any remaining blackberry seeds that try to sprout.
 

3. Repeat Treatments as Needed

Don’t be discouraged if blackberries pop back up after a few months.
 
Just repeat your chosen method, and over one or two growing seasons, you really can get rid of blackberries for good.
 

So, How Do You Get Rid of Blackberries for Good?

You get rid of blackberries for good by combining methods like digging, smothering, mowing, and targeted herbicide use until the roots are completely starved out.
 
There’s no single trick that works overnight, but consistency is what gets rid of blackberries permanently.
 
Stay on top of new growth, be patient, and your yard will finally be blackberry-free.
