Row of thornless blackberries in a row

Row of thornless blackberries in a row.

Thornless blackberry, just like raspberry, requires supports to spread the shoots. When growing blackberry outdoors, its shoots can be spread on scaffolding, the same as for raspberry. In amateur cultivation, fences or walls can be used as supports.

Planted blackberries need to be trimmed in the spring at a distance 30 cm from the ground. The shoots growing during the summer are unfolded in the form of a fan and tied to the supports. Thornless blackberry shoots are not resistant to frost and therefore they must be removed from the supports before frost., put on the ground and cover with straw.

Blackberry bears fruit in the second year after planting. In spring, shoots need to be picked up and reattached with knitting needles. Very long shoots can be trimmed after spreading over the last wire. Already in May, shoots emerge from the root collar, which will bear fruit in the next year. These shoots are led vertically upwards and loosely tied to the scaffolding (Lynx.).

In late autumn, cut fruit-bearing shoots near the ground and throw them away. Place the young shoots of this year on the ground to cover. The activities in the following years are the same as in the second year.
