You can take cuttings from a blackberry plant and grow new ones that are exact clones of the parent.
If you’ve been wondering how to take cuttings from a blackberry plant, the good news is it’s easier than you might think.
Blackberry plants root readily from cuttings when you give them the right conditions and timing.
In this post, we’ll walk through exactly how to take cuttings from a blackberry plant, when to do it, and how to care for them so they thrive.
Let’s dig in.
How to Take Cuttings from a Blackberry Plant
Taking cuttings from a blackberry plant starts with choosing the right stems and using clean tools.
Here’s how to do it step by step.
1. Choose the Right Time of Year
The best time to take cuttings from a blackberry plant is in late summer or early fall.
At this point, the canes are mature enough to root but still flexible.
You can also take softwood cuttings from a blackberry plant in early summer if you’re working with new growth.
Just avoid taking cuttings in the dead of winter when the plant is dormant.
2. Select Healthy Canes
Look for canes that are disease-free and about the thickness of a pencil.
Avoid any stems that show signs of pests, spots, or damage.
When you take cuttings from a blackberry plant, you want the healthiest material possible.
Healthy canes give you the best chance of successful rooting.
3. Make the Cut
Using sharp, sterilized pruning shears, cut a 4 to 6 inch section from the tip of a healthy cane.
Make your cut just below a leaf node, which is where roots will form.
Each cutting should have at least two or three leaf nodes.
Strip the leaves from the bottom half of the cutting, leaving a few at the top.
4. Dip in Rooting Hormone
While it’s optional, dipping the cut end in rooting hormone can speed up the process.
This is especially helpful when you take cuttings from a blackberry plant that’s a bit stubborn.
Just dip the bottom inch into the hormone powder or gel and tap off the excess.
5. Plant the Cuttings
Fill a pot with a mix of peat moss and perlite for good drainage.
Poke a hole in the soil and insert the cut end of your blackberry cutting about 2 inches deep.
Firm the soil around the stem to hold it in place.
Water gently until the soil is moist but not soggy.
Best Conditions for Rooting Blackberry Cuttings
Once you’ve taken cuttings from a blackberry plant, the next step is giving them the right environment to root.
Here’s what they need to thrive.
1. Humidity and Moisture
Blackberry cuttings need high humidity to root successfully.
Cover the pot with a plastic bag or place it in a propagator to trap moisture.
Mist the cuttings daily to keep the leaves from drying out.
2. Indirect Light
Place your cuttings in bright, indirect light.
Direct sunlight can scorch the leaves and dry out the cuttings before they root.
A windowsill that gets soft morning light works great.
3. Warmth
Keep the soil temperature around 65–75°F (18–24°C).
A heat mat underneath the pot can help maintain consistent warmth.
Warmth encourages faster root development when you take cuttings from a blackberry plant.
How Long Do Blackberry Cuttings Take to Root?
When you take cuttings from a blackberry plant, expect roots to form in about 4 to 8 weeks.
You’ll know they’ve rooted when you see new growth at the top.
You can also give the cutting a gentle tug.
If it resists, roots have formed and it’s ready for the next stage.
1. Transplanting Rooted Cuttings
Once your blackberry cuttings have a healthy root system, transplant them into larger pots or directly into the ground.
Choose a spot with full sun and well-drained soil.
Water them regularly during the first few weeks after transplanting.
2. Acclimating Before Planting Out
Before you plant your rooted cuttings outdoors, harden them off gradually.
Move them outside for a few hours each day over the course of a week.
This helps them adjust to outdoor conditions without shock.
Common Mistakes to Avoid
Taking cuttings from a blackberry plant isn’t complicated, but a few missteps can ruin your efforts.
Here’s what to watch out for.
1. Using Dirty Tools
Always sterilize your pruning shears before you take cuttings from a blackberry plant.
Dirty tools can introduce bacteria and disease that kill your cuttings.
2. Letting Cuttings Dry Out
Blackberry cuttings dry out fast.
Keep them in a humid environment and never let the soil go completely dry.
3. Skipping the Hardening Off Process
Jumping straight from indoors to the garden can shock your cuttings.
Take the time to acclimate them properly for the best results.
So, How Do You Take Cuttings from a Blackberry Plant?
You take cuttings from a blackberry plant by selecting healthy canes, cutting 4 to 6 inch sections, and rooting them in a moist, humid environment.
With the right timing and a little patience, those cuttings will grow into productive blackberry plants.
Just remember to keep them warm, moist, and out of direct sunlight while they root.
Before you know it, you’ll have new blackberry plants ready to fruit in your garden.
