How To Get Rid Of Overgrown Blackberry Bushes

Getting rid of overgrown blackberry bushes takes persistence and a solid plan, but you can absolutely reclaim your yard.
 
Those thorny tangles didn’t take over overnight, so removing them properly means attacking the roots, not just the canes you can see.
 
If you’ve been staring at a massive blackberry thicket wondering how to get rid of overgrown blackberry bushes without losing your mind, you’re in the right place.
 
In this post, we’ll walk through the best ways to get rid of overgrown blackberry bushes, from manual digging to chemical control, so you can enjoy your outdoor space again.
 

How to Get Rid of Overgrown Blackberry Bushes

Getting rid of overgrown blackberry bushes starts with understanding what you’re dealing with.
 
Blackberries spread through sprawling canes that root at the tips and an underground root system that keeps sending up new shoots.
 
That’s why simply cutting the visible growth rarely works, because the roots stay alive and push out fresh canes within weeks.
 
To truly get rid of overgrown blackberry bushes, you need a strategy that targets both the top growth and the roots.
 

1. Start With Protective Gear

Before you touch a single cane, suit up because blackberry thorns are unforgiving.
 
Wear thick leather gloves, long sleeves, long pants, and eye protection to avoid scratches and cuts.
 
Sturdy boots are a must too since blackberry patches often hide uneven ground and debris.
 

2. Cut Back the Canes First

The easiest first step in getting rid of overgrown blackberry bushes is to cut the canes down to the ground.
 
Use loppers, a brush cutter, or a hedge trimmer to clear the bulk of the growth.
 
This won’t kill the plant, but it makes the area manageable and lets you see where the roots are.
 
Bag up the cuttings and dispose of them rather than composting, since blackberry canes can re-root.
 

Manual Methods to Get Rid of Overgrown Blackberry Bushes

If you prefer to avoid chemicals, manual removal is a reliable way to get rid of overgrown blackberry bushes.
 
It’s more labor-intensive, but it works well for smaller patches or if you’re patient.
 

1. Dig Out the Root Ball

The key to getting rid of overgrown blackberry bushes manually is removing the crown and main roots.
 
Use a mattock, shovel, or digging fork to loosen the soil around the base of the plant.
 
Then pull up the root ball, which often looks like a woody knot with thick roots spreading outward.
 
If you leave any major roots behind, new canes will pop up, so be thorough.
 

2. Sift Through the Soil

After removing the main root ball, go back through the soil to find smaller roots and runners.
 
Blackberry roots can travel several feet underground, so a quick dig isn’t enough.
 
Turn the soil over with a fork and pick out any roots you find.
 
This step makes a huge difference in whether the blackberry bushes come back.
 

3. Repeat as Needed

Even with careful digging, some roots will survive, and new shoots will appear.
 
Check the area every couple of weeks and pull up any new growth immediately.
 
Consistency is what finally gets rid of overgrown blackberry bushes for good.
 

Using Herbicides to Kill Overgrown Blackberry Bushes

When manual removal isn’t enough, herbicides can help get rid of overgrown blackberry bushes, especially large infestations.
 
The most effective option is a systemic herbicide that travels down into the roots.
 

1. Choose the Right Herbicide

Look for products containing glyphosate or triclopyr, which are commonly used for woody plants.
 
These herbicides move through the plant and kill the roots, not just the leaves.
 
Always follow the label instructions carefully and check local regulations before applying.
 

2. Apply at the Right Time

The best time to spray is late summer or early fall when the plant is actively storing energy in its roots.
 
Cut the canes back first, then spray the fresh cuts or the new regrowth.
 
This timing helps the herbicide work more effectively to get rid of overgrown blackberry bushes.
 

3. Protect Nearby Plants

Herbicides don’t discriminate, so shield desirable plants with cardboard or plastic before spraying.
 
Spray on a calm day to avoid drift, and avoid applying when rain is forecast.
 
It may take a few applications, but this method can get rid of overgrown blackberry bushes completely.
 

Preventing Blackberry Bushes From Coming Back

Once you’ve done the hard work of getting rid of overgrown blackberry bushes, the last thing you want is a repeat.
 
Blackberries are persistent, so a little prevention goes a long way.
 

1. Monitor the Area

Keep an eye on the cleared spot for at least a year.
 
Pull up any new shoots while they’re small and easy to remove.
 
Early action stops them from reestablishing a root system.
 

2. Mulch or Plant Competitively

Cover the ground with a thick layer of mulch or plant fast-growing ground covers.
 
This blocks sunlight and makes it harder for blackberry seeds and roots to thrive.
 
A healthy lawn or dense shrubs can also crowd out new blackberry growth.
 

3. Stay Consistent

The real secret to getting rid of overgrown blackberry bushes is consistency.
 
Check the area regularly, especially in spring when growth takes off.
 
A few minutes of maintenance each week saves you from another major removal project later.
 

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

You get rid of overgrown blackberry bushes by combining cutting, root removal, and, if needed, targeted herbicide applications.
 
It’s not a one-and-done task, but with patience and repetition, you can clear even the worst blackberry thicket.
 
Whether you go the manual route or use herbicides, the key is to attack the roots and stay consistent.
 
With a solid plan and a little elbow grease, you’ll finally get rid of overgrown blackberry bushes and take back your yard.
