In principle, blackberries can also be grown from the seeds of the fruit if they are stratified and sown with a lot of patience. Due to the long duration, however, this propagation method has almost no meaning for blackberries.

Things to know about propagation by cuttings
The cutting and rooting of cuttings is a vegetative propagation method, so that all plants grown are identical to the mother plant in terms of their variety and genetics. When propagating blackberries, the technique of propagating cuttings is also to be favored, as this saves time in terms of the cultivation time until the first harvest. If you want to grow new blackberry plants from cuttings yourself, you should ideally take the cuttings in August or September.
Cut cuttings to the right length
For the propagation of cuttings in late summer, you can cut a harvested blackberry tendril into pieces with sharp planting scissors. This is particularly practical, as blackberries are always cut back on biennial tendrils and harvested tendrils are cut back close to the ground anyway. The cuttings should be cut so that they each have three to four leaf nodes. Except for the upper pair of leaves, all others are stripped off, then you should put the cuttings with the lower end about two leaf buds far into loose soil substrate for rooting.
Encourage rooting with moisture and warmth
First you can put several cuttings in a pot and place it in a warm place in the greenhouse or on the balcony. When caring for these cuttings, you should pay attention to protection from freezing temperatures and adequate watering. Under optimal conditions, blackberry cuttings can develop roots within about four weeks. In the spring you can then transplant the overwintered cuttings into a single pot. With good care, the offshoots will then be strong enough by autumn to be planted out in their final location outdoors.
tips and tricks
A larger number of plants is required for a trellis or a hedge of blackberry plants in particular. You can produce these inexpensively by propagating cuttings yourself, in order to then plant the plants at their destination the following year.
