How Do You Get Rid Of Blackberries

You get rid of blackberries by digging out the roots, smothering the canes, or using a targeted herbicide, and persistence is the key to winning the battle.
 
If you’ve been asking yourself “how do you get rid of blackberries?” because they’ve taken over your garden, you’re in the right place.
 
Getting rid of blackberries isn’t a one-and-done task, but it’s absolutely doable with the right approach.
 
In this post, we’ll walk through how to get rid of blackberries using methods that actually work, from manual digging to chemical control, so you can reclaim your outdoor space.
 
Let’s dig in.
 

Why Getting Rid of Blackberries Takes Real Effort

Getting rid of blackberries is tough because these plants are built to survive.
 
Understanding why they’re so stubborn helps you plan a smarter attack.
 

1. Blackberries Spread Through Aggressive Root Systems

The main reason getting rid of blackberries is so challenging comes down to their roots.
 
Blackberry plants send out deep taproots plus sprawling lateral roots that can travel several feet underground.
 
Even a small piece of root left behind can sprout a whole new plant.
 
That’s why simply cutting the canes back rarely works on its own.
 

2. The Canes Root Wherever They Touch Soil

Blackberry canes arch over and root into the ground wherever their tips make contact.
 
This means one plant can quietly become a thicket in a single season.
 
If you’re getting rid of blackberries, you have to watch for these rooted tips, not just the main clump.
 

3. Seeds Stay Viable in the Soil for Years

Birds and animals drop blackberry seeds everywhere, and those seeds can stay dormant in the soil for years.
 
So even after you remove a mature plant, new blackberries can pop up from the seed bank.
 
This is why getting rid of blackberries often means playing the long game.
 

How Do You Get Rid of Blackberries: Methods That Work

So, how do you get rid of blackberries for good?
 
Here are the most effective methods, and honestly, combining a few of them works best.
 

1. Dig Out the Roots by Hand

Digging is the most eco-friendly way of getting rid of blackberries.
 
Use a digging fork or mattock to loosen the soil around the base, then pull out the crown and as much of the root system as you can.
 
Work when the soil is moist so the roots slide out more easily.
 
This method works great for small patches, but you’ll need to recheck the area for regrowth every few weeks.
 

2. Smother the Patch with Mulch or Landscape Fabric

If digging feels like too much, smothering is a solid option for getting rid of blackberries.
 
Cut the canes down to the ground, then cover the area with thick black plastic, cardboard, or heavy landscape fabric.
 
Weigh it down so no light gets through.
 
Without sunlight, the roots eventually starve and die, though this can take a full growing season or more.
 

3. Use a Targeted Herbicide

For large infestations, herbicide can help with getting rid of blackberries.
 
Choose a product formulated for woody weeds and apply it to freshly cut canes or to the leaves during active growth.
 
Always follow the label instructions and protect nearby plants, pets, and yourself.
 
Herbicide works best in late summer or early fall when the plant is pulling energy down into its roots.
 

4. Mow and Repeat

Regular mowing won’t kill blackberries overnight, but it wears them down over time.
 
Every time new growth appears, cut it back before it can flower or set seed.
 
This starves the root system and is a key part of getting rid of blackberries in larger areas like fields or fence lines.
 

Tips for Keeping Blackberries Gone

Once you’ve done the hard work of getting rid of blackberries, don’t let them sneak back.
 
Monitor the area regularly, especially in spring when new shoots appear.
 
Pull any seedlings while they’re small and easy to remove.
 
Maintain a thick layer of mulch or keep the ground covered with grass or other ground cover to crowd out new growth.
 
And if you spot a stray cane, deal with it immediately rather than letting it establish.
 
Staying consistent is the real secret to getting rid of blackberries and keeping them away.
 

So, How Do You Get Rid of Blackberries?

You get rid of blackberries by digging out the roots, smothering the canes, or using a targeted herbicide, and persistence is what makes it stick.
 
Getting rid of blackberries isn’t a one-and-done task, but it’s absolutely doable with the right approach.
 
Whether you dig, smother, mow, or spray, the key is to stay consistent and keep an eye out for regrowth.
 
Hope this post has helped you understand how to get rid of blackberries and the best methods to finally win the battle.
