How to Grow Blackberries From Cuttings

Overview

Blackberries prefer cold winters and warm summers. They grow in USDA hardiness zones 4 through 10 but thrive best in zones 5 through 8. There are several methods of propagating blackberries, all fairly simple. One of the easiest is sprouting root cuttings.

Step 1

Cut several pencil-thick blackberry roots that are 3 to 6 inches long. Take the cuttings in the fall, when the plant is losing its leaves and beginning to go dormant.

Step 2

Place the root cuttings in a plastic baggie along with some damp peat moss. Seal the baggie and place it in the vegetable crisper of your refrigerator and leave it there until the following spring.

Step 3

Remove the baggie from your refrigerator once all possibility of frost is gone from your area. Allow the cuttings to thaw on a damp paper towel overnight.

Step 4

Choose a sunny, well-drained location. Loosen the soil in your garden and mix potting soil with your garden soil until the mixture is approximately 50/50. Make 1-inch-deep trenches in the soil and lay the blackberry roots horizontally in each trench and gently cover with soil. Plant roots 3 feet apart with rows at least 18 inches apart.

Step 5

Water the soil gently but thoroughly. Keep the soil damp but not soggy. Your blackberries should begin to sprout within 14 to 21 days.
