How to Propagate Dewberries

Dewberries, a trailing cousin to standard blackberries, grow similarly to other trailing fruits. A thicket of dewberries may ripen earlier than blackberries, with thin canes growing horizontally over the thicket. When you wish to propagate dewberries, use the simple method of tip-layering. Because dewberry canes root easily if they touch the soil, this propagation method requires little time or effort.

Instructions

    • 1

      Cultivate the soil around the dewberries in late summer. Lightly scratch the soil surface with the hand rake to make it easier to bury the tips of the dewberry canes.

    • 2

      Pull long and healthy canes down to the soil. Position the canes so they stretch easily down to the soil at least 12 inches away from the mother plants. Space each cane at least 12 inches apart.

    • 3

      Make holes with the hand trowel and bury the tips of the canes about 4 inches below the soil. Firm the soil gently with your hands.

    • 4

      Water the soil evenly after you tip-layer the dewberries. Allow the dewberries to root undisturbed until the following spring.

    • 5

      Clip the canes the following spring with pruning shears, leaving about 6 to 8 inches of the rooted cane on the new dewberry plants. Dig up the propagated dewberry plants carefully with a spade and make new 6-inch-deep holes for them. Space the holes about 18 inches apart. Place the new plants in the holes and fill the holes halfway with soil. Add more soil to the hole over the growing season until the soil becomes even with the surrounding soil.
