You can get rid of blackberries naturally by smothering them, cutting them back, and exhausting the roots over time.
It’s not an overnight fix, but it’s the safest way to clear a patch without drenching your yard in harsh chemicals.
If you’ve been asking how to get rid of blackberries naturally, the good news is that these stubborn plants can be beaten with patience and a few simple tools.
You can get rid of blackberries naturally by combining physical removal with natural smothering methods.
In this post, we’ll walk through why natural removal works, the best natural ways to get rid of blackberries, and how to make sure they don’t come roaring back.
Let’s dig in.
Why You Can Get Rid of Blackberries Naturally
You can get rid of blackberries naturally, and the reason comes down to how the plant survives.
Blackberries spread through tough root systems and cane tips that root wherever they touch soil.
If you cut off its access to sunlight, water, and air, the plant has no way to keep feeding those roots.
That’s why natural methods work, they target the plant’s lifeline instead of just the top growth.
1. Blackberries Rely Heavily on Their Roots
Every cane above ground is connected to a deep, woody root crown.
That crown stores energy and sends up new shoots even after you chop the visible canes.
Natural methods focus on starving or exhausting this root system so blackberries can’t bounce back.
2. Sunlight Is Their Fuel
Blackberries can’t survive long without light.
Blocking the sun with a covering stops photosynthesis, which is how the plant makes food.
Once that food supply stops, the roots slowly die off.
3. Natural Methods Spare Your Soil
Chemical herbicides can linger in soil and harm nearby plants, pets, and pollinators.
When you get rid of blackberries naturally, you protect the beneficial life in your garden.
That matters if you plan to plant something else in that same spot later.
The Best Natural Ways to Get Rid of Blackberries
Here are the most effective natural ways to get rid of blackberries, and you can combine several for faster results.
1. Cut and Smother With Cardboard
Start by cutting the canes down to the ground with loppers or a brush cutter.
Then lay thick cardboard over the entire patch, overlapping the edges so no light sneaks through.
Cover the cardboard with mulch, wood chips, or soil to weigh it down.
This smothering method starves the roots of light and eventually kills them.
2. Use a Thick Tarp or Black Plastic
If you want to get rid of blackberries naturally without cardboard, a heavy tarp works too.
Black plastic or a woven landscape fabric blocks sunlight and traps heat.
Let it sit for several months, especially through summer, to cook the roots underneath.
3. Dig Out the Root Crowns
For smaller patches, digging is one of the most reliable natural methods.
Use a mattock or shovel to lift the root crowns out of the soil.
Blackberry roots can run deep and wide, so remove as much of the crown as you can.
Any piece left behind can regrow, so check the area again after a few weeks.
4. Smother With Heavy Mulch
A thick layer of bark mulch, straw, or wood chips can help suppress regrowth.
Mulch alone won’t kill established roots, so pair it with cardboard for best results.
Aim for at least 4 to 6 inches of mulch to block light effectively.
5. Repeat Cutting Every Few Weeks
If you keep cutting new shoots to the ground, the roots run out of stored energy.
Do this every two to three weeks during the growing season.
It’s a slow but natural way to get rid of blackberries without chemicals.
6. Pour Boiling Water on New Shoots
Boiling water kills young shoots and weakens the root system over time.
Pour it directly on emerging canes, being careful not to splash nearby plants.
This works best as a follow-up after you’ve cut back the main patch.
Mistakes to Avoid When Removing Blackberries Naturally
Even with the right approach, a few mistakes can let blackberries win.
1. Leaving Roots Behind
Pulling just the canes won’t work because the roots stay alive and send up new growth.
Always target the root crown if you truly want to get rid of blackberries naturally.
2. Composting the Canes
Blackberry canes can root from cuttings, so don’t toss them in your compost pile.
Bag them up and dispose of them instead to avoid spreading the plant.
3. Giving Up Too Soon
Blackberries are persistent, and regrowth is normal in the first season.
Stay consistent with cutting and smothering, and the patch will weaken over time.
So, How Do You Get Rid of Blackberries Naturally?
You can get rid of blackberries naturally by cutting them back, smothering the roots, and repeating until the plant gives up.
It takes patience, but it’s a safe and effective way to clear your yard without chemicals.
Combine digging, mulching, and repeated cutting for the best results.
Stay consistent, and your blackberry patch will finally be gone.
