You can take cuttings from a blackberry plant and grow new ones fairly easily once you know a few simple steps.
The good news is that blackberry plants root quite willingly from cuttings, so even a beginner can have success.
Whether you want to expand your berry patch or share plants with a friend, taking blackberry cuttings is a rewarding project.
In this post, we’ll walk through how to take cuttings from a blackberry plant, when to do it, and how to care for them until they’re ready to plant out.
Let’s dig in.
How to Take Cuttings from a Blackberry Plant
Learning how to take blackberry cuttings starts with choosing the right stems and timing your snips correctly.
Blackberries are usually propagated from what are called root cuttings or tip layering, but stem cuttings work well too when done right.
Here’s how to take cuttings from a blackberry plant step by step.
1. Pick the Right Time of Year
The best time to take blackberry cuttings is in late winter or early spring while the plant is still dormant.
During dormancy, the plant’s energy is stored in its stems and roots, which gives your cuttings the best chance to root.
If you take blackberry cuttings in the middle of summer, the plant is focused on fruiting rather than rooting, so success rates drop.
2. Choose Healthy Canes
Look for canes that are firm, disease-free, and about the thickness of a pencil.
Avoid any blackberry stems that look damaged, discolored, or have signs of pests.
The healthiest canes give you the healthiest blackberry plants later on.
3. Make Your Cuts
Using clean, sharp pruners, cut a section of cane about 4 to 6 inches long.
Make your cut just below a leaf node, since that’s where new roots tend to form.
If you’re taking several blackberry cuttings at once, keep them in a damp paper towel so they don’t dry out.
Preparing and Planting Your Blackberry Cuttings
Once you’ve taken your blackberry cuttings, the next step is preparing them for rooting.
This part is where a lot of people rush and then wonder why their blackberry cuttings didn’t take.
1. Strip the Lower Leaves
Remove the leaves from the bottom half of each blackberry cutting.
This keeps the leaves from rotting in the soil and directs the plant’s energy toward root growth.
Leave a couple of leaves at the top if you’re taking softwood blackberry cuttings in early spring.
2. Dip in Rooting Hormone
Dipping the cut end in rooting hormone powder or gel can speed things up.
It’s not strictly necessary for blackberry cuttings, but it does improve your odds, especially with harder wood.
Just dip the bottom inch, tap off the excess, and you’re ready to plant.
3. Plant in the Right Medium
Use a light, well-draining mix like half peat moss and half perlite.
Plant each blackberry cutting about 2 inches deep, with the leaf nodes buried.
Water gently so the soil settles around the cutting without washing it out.
Caring for Blackberry Cuttings Until They Root
Caring for your blackberry cuttings is mostly about moisture, warmth, and patience.
If you get these basics right, most blackberry cuttings will root within four to eight weeks.
1. Keep the Humidity High
Cover your pots with a plastic bag or place them in a humidity dome.
This keeps moisture in the air around the blackberry cuttings, which prevents them from drying out before roots form.
Open the cover for a few minutes every couple of days to let fresh air in and prevent mold.
2. Provide Indirect Light
Place your blackberry cuttings in bright, indirect light rather than direct sun.
Harsh sun can scorch the leaves and dry out the cuttings before they’ve had a chance to root.
A windowsill or a shaded greenhouse spot works great.
3. Water Consistently
Keep the soil moist but never soggy, since blackberry cuttings rot easily in waterlogged soil.
Check the soil every few days and water when the top inch feels dry.
4. Test for Roots Gently
After about a month, give one blackberry cutting a gentle tug.
If it resists, roots have formed and it’s time to start hardening them off.
If it pulls right out, give it more time and keep the conditions steady.
Transplanting Rooted Blackberry Cuttings
Once your blackberry cuttings have a healthy root system, you can move them into bigger pots or the ground.
Harden them off slowly over a week before planting them in their permanent spot.
Choose a sunny location with well-draining soil, and space your new blackberry plants about 3 to 4 feet apart.
Water them well after transplanting and keep the soil consistently moist for the first few weeks.
So, How Do You Take Cuttings from a Blackberry Plant?
You can take cuttings from a blackberry plant by choosing healthy dormant canes, cutting 4 to 6 inch sections, and rooting them in a light, moist mix.
With the right timing, humidity, and a little patience, blackberry cuttings root without much fuss.
Whether you’re growing a few new blackberry plants for yourself or sharing them with neighbors, this simple method works every time.
Happy planting.
