Propagating Blackberries: A Guide for Beginners
Blackberries are delicious and nutritious fruits that are easy to grow at home. They can be propagated through various methods, including cuttings, suckers, and tip layering.
Propagation by Cuttings
Blackberries can be propagated through leafy stem cuttings or root cuttings. Leafy stem cuttings are the most common method, and they are usually taken while the cane is still firm and succulent. You’ll want to take about 4-6 inches (10-15 cm.) of the cane stems and place them in a moist peat/sand mix, sticking them in a couple inches deep.
Tip: Rooting hormone can be used to promote root growth, but it is not necessary.
Mist the cuttings well and place them in a shady location. Within three to four weeks, roots should begin to develop.
Root cuttings are also used for blackberry propagation. These cuttings are taken in fall during dormancy and are usually about 3-6 inches (7.5-15 cm.) long. They require a three-week cold storage period before being planted.
Once the cuttings have been taken, they should be bundled together (with similar cuts end to end) and cold stored at about 40 degrees F. (4 C.) outdoors in a dry area or in the refrigerator.
After the cold period, the cuttings can be planted in a moist peat and sand mix, about 2-3 inches (5-7.5 cm.) apart with straight ends inserted a couple inches into the soil.
Propagation by Suckers
Suckers are one of the easiest ways to propagate blackberries. Suckers are new shoots that grow from the roots of the parent plant. They can be removed from the parent plant and then replanted elsewhere.
To propagate blackberries by suckers, simply dig up the sucker, making sure to get as much of the root system as possible. Then, replant the sucker in a new location.
Propagation by Tip Layering
Tip layering is another method that can be used for blackberry propagation. This method works well for trailing types of blackberries and when only a few plants are needed.
To propagate blackberries by tip layering, simply bend a young shoot over to the ground and cover it with a few inches of soil. This will encourage the shoot to develop roots.
By spring, there should be enough root formation to cut the plant away from the parent and replant elsewhere.
Tips for Successful Propagation
- Use clean, sharp tools to take cuttings.
- Keep the cuttings moist but not soggy.
- Provide plenty of sunlight for the cuttings.
- Be patient! It may take several weeks or even months for the cuttings to develop roots.
With a little patience and care, you can easily propagate blackberries and enjoy fresh, delicious berries for years to come.
