How To Propagate Thornless Blackberries

You can propagate thornless blackberries fairly easily once you know which method suits your setup.
 
The great news is that thornless blackberries propagate just like their thorny cousins, so you won’t need any special tools or skills.
 
If you’ve been wondering how to propagate thornless blackberries, you’ve come to the right place.
 
In this post, we’ll walk through the best ways to propagate thornless blackberries, including tip layering, rooting cuttings, and dividing established plants.
 
Let’s dig in.
 

Why Propagating Thornless Blackberries Works So Well

Thornless blackberries propagate so well because these plants naturally spread through their canes.
 
Here’s why propagating thornless blackberries is such a reliable project:
 

1. Thornless Blackberries Root at the Tips

Thornless blackberries have a natural habit of bending their canes to the ground, where the tips root on their own.
 
This means you can propagate thornless blackberries simply by helping that process along.
 
The plant does most of the work for you, which is why beginners love propagating thornless blackberries.
 

2. They Grow True to the Parent Plant

When you propagate thornless blackberries from cuttings or layering, you get exact copies of the parent.
 
That means your new blackberry plants will also be thornless and produce the same tasty berries.
 
This is a big reason gardeners prefer propagating thornless blackberries over growing from seed.
 

3. Thornless Blackberries Are Vigorous Growers

Thornless blackberries put out lots of new canes every season, giving you plenty of material to work with.
 
Healthy canes root quickly, so propagating thornless blackberries rarely fails if you keep the soil moist.
 
You can easily turn one blackberry plant into several within a single growing season.
 

How to Propagate Thornless Blackberries by Tip Layering

Tip layering is the simplest way to propagate thornless blackberries, and it happens almost on its own.
 
Here’s how to propagate thornless blackberries step by step:
 

1. Choose a Healthy Cane in Late Summer

Pick a long, flexible cane from your thornless blackberry plant.
 
Bend the tip down to the soil and let it touch the ground naturally.
 

2. Bury the Tip About Two Inches Deep

Dig a shallow hole and bury the tip of the cane a couple of inches into the soil.
 
Cover it lightly and water it well to encourage rooting.
 

3. Wait a Few Weeks for Roots to Form

Within a few weeks, the buried tip will develop roots while still attached to the parent plant.
 
Once roots are established, cut the cane from the parent and transplant your new thornless blackberry.
 

How to Propagate Thornless Blackberries from Cuttings

If you want more control, propagating thornless blackberries from cuttings is the way to go.
 
Here’s how to propagate thornless blackberries using stem cuttings:
 

1. Take Cuttings in Early Spring

Cut six-inch sections from healthy, disease-free canes of your thornless blackberry plant.
 
Make sure each cutting has at least two or three leaf nodes.
 

2. Remove Lower Leaves and Dip in Rooting Hormone

Strip the leaves from the bottom half of each cutting.
 
Dip the cut end in rooting hormone to boost your chances of success when propagating thornless blackberries.
 

3. Plant in Moist Potting Mix

Stick the cuttings into a pot filled with moist, well-draining potting mix.
 
Keep them in indirect light and mist regularly until roots form in about four to six weeks.
 

How to Propagate Thornless Blackberries by Division

Division is another reliable way to propagate thornless blackberries, especially if you already have a big clump.
 
Here’s how to propagate thornless blackberries through division:
 

1. Dig Up Suckers in Dormant Season

In late winter or early spring, look for new shoots growing near the base of your thornless blackberry plant.
 
These suckers are perfect for propagating thornless blackberries.
 

2. Separate the Roots Carefully

Use a sharp spade to cut the suckers away from the main plant, keeping some roots attached.
 
This gives each new thornless blackberry a strong start.
 

3. Replant and Water Well

Plant your new thornless blackberries in a sunny spot with well-draining soil.
 
Water them deeply and keep the soil moist while they settle in.
 

Tips for Propagating Thornless Blackberries Successfully

A few simple habits make propagating thornless blackberries much easier.
 
Always use clean, sharp tools to avoid spreading disease between plants.
 
Keep your new thornless blackberries watered but never soggy, since soggy soil causes rot.
 
Give them plenty of sunlight and space so air can move freely around the canes.
 
And be patient, because propagating thornless blackberries takes a little time before you see real growth.
 

So, How Do You Propagate Thornless Blackberries?

You propagate thornless blackberries by tip layering, rooting cuttings, or dividing established plants.
 
All three methods work well, and each one gives you new thornless blackberries that grow true to the parent.
 
Tip layering is the easiest, cuttings give you more control, and division is great for expanding an existing patch.
 
Pick the method that fits your garden, keep the soil moist, and you’ll soon have plenty of thornless blackberries to enjoy.
