Do Blackberries Send Out Runners

Blackberries send out runners, and that’s actually one of the main ways they spread and multiply in your garden.
 
If you’ve ever wondered do blackberries send out runners, the short answer is a big yes, and those runners are exactly why this plant can take over an area faster than you’d expect.
 
Blackberry plants send out runners as a natural survival strategy and understanding this growth habit is the key to keeping your patch productive instead of chaotic.
 
In this post, we’ll look at how blackberry runners work, how to tell them apart from suckers, and how to manage them so your plants stay healthy and under control.
 

Why Blackberries Send Out Runners

Blackberries send out runners because that’s their built-in way of expanding and creating new plants without waiting for seeds.
 
These runners, often called stolons, are stems that grow horizontally along or just below the soil surface and eventually root and form brand-new blackberry plants.
 

1. Runners Are a Natural Propagation Method

The main reason blackberries send out runners is reproduction.
 
Unlike some plants that depend entirely on seeds, blackberries hedge their bets by sending out runners that become clones of the parent plant.
 
This means every new blackberry that forms from a runner shares the exact same genetics as the original, which is why a single healthy plant can turn into a whole thicket in a couple of seasons.
 

2. Blackberry Runners Help the Plant Spread Fast

In the wild, blackberries send out runners to claim new ground quickly.
 
If one spot gets shaded out or dries up, the runners have already pushed into fresher soil nearby.
 
That’s why wild blackberry patches seem to appear out of nowhere and just keep growing outward year after year.
 

3. Not All Blackberry Varieties Send Out Runners

Here’s something worth knowing: not every blackberry plant sends out runners equally.
 
Trailing blackberries and many wild varieties send out runners aggressively, while some erect, thornless cultivars like ‘Navaho’ and ‘Apache’ grow in clumps and send out far fewer runners.
 
So if you’re planning a blackberry patch, checking whether your variety sends out runners can save you a lot of future digging.
 

How to Tell Blackberry Runners From Suckers

Blackberry runners and suckers both spread the plant, but they behave differently, and knowing the difference helps you manage them correctly.
 

1. Runners Grow Horizontally Above Ground

Blackberry runners are stems that travel along the soil surface, rooting wherever they touch down.
 
You’ll usually spot them creeping away from the main crown, sometimes several feet out, looking for a place to settle.
 

2. Suckers Come Up From the Roots

Suckers, on the other hand, shoot straight up from the root system, often close to the base of the parent plant.
 
They look like new canes but they’re growing from underground roots rather than a traveling stem.
 

3. Both Spread the Blackberry Patch

Whether it’s runners or suckers, the result is the same: your blackberry patch gets bigger.
 
That’s why knowing how blackberries send out runners and suckers matters if you want to keep things tidy.
 

How to Control Blackberry Runners

Controlling blackberry runners isn’t hard, but it does require a bit of routine attention.
 

1. Plant With a Root Barrier

If you’re planting blackberries that send out runners, install a physical root barrier around the bed.
 
A buried barrier at least 12 to 18 inches deep stops runners from sneaking into your lawn or flower beds.
 

2. Mow or Cut Runners Regularly

Any blackberry runners that escape your barrier can be mowed or cut back with pruners.
 
Do this while they’re still young and tender because older, rooted runners are tougher to remove.
 

3. Dig Up Rooted Runners

If a runner has already rooted, grab a shovel and dig it out completely.
 
Leaving even a small piece of root behind means the blackberry will likely send out runners again from that spot.
 

4. Use Runners to Grow New Plants

Here’s the fun part: you can actually use blackberry runners to grow new plants on purpose.
 
Just let a healthy runner root, then cut it free from the parent and transplant it wherever you want.
 
That’s an easy, free way to expand your blackberry harvest without buying more plants.
 

Do Blackberries Send Out Runners? Final Answer

Blackberries send out runners, and they do it as a natural way to spread and reproduce.
 
Those runners are why a single blackberry plant can quietly turn into a sprawling patch if you’re not paying attention.
 
The good news is that blackberry runners are easy to manage with a barrier, some regular pruning, and a little digging when needed.
 
And if you want more plants, you can let a few runners root and start brand-new blackberry bushes for free.
