Be careful with wild blackberries
Due to the rapid spread and the aromatic fruits, some hobby gardeners are tempted to plant wild blackberry plants on suitable areas in the garden. However, you should think twice about such a project. Once the roots of the wild blackberry plants have grown through the soil at a location for one or two years, later removal is only possible with relatively great effort. Since wild blackberries multiply by themselves via the roots and via sinkers, the usual delimitation of bamboo with bars or curbs would not be successful.

Propagate blackberry yield varieties in the garden
The blackberry varieties bred for the garden usually multiply by themselves far less strongly than their wild relatives. Nevertheless, it can sometimes lead to the formation of subterranean root runners, which, if necessary, can be pricked off with enough roots and replanted at another location. Overall, the following types of propagation are available for blackberries:
In principle, sowing and mossing are also possible with blackberries, but are of no practical importance due to the great effort and time required.
Propagation by cuttings
If you want to propagate blackberries from cuttings, this has the advantage that the rooted young plant already has a certain size and can therefore deliver a yield more quickly. Annual branches of the blackberry plant are ideally used for this. But you can also use the harvested rods, which you cut near the ground in autumn anyway. Divide the blackberry sticks so that there are always three to four pairs of leaves on each piece. Then remove the bottom two and insert the cuttings deep into a loose growing medium.

In the following year, the young blackberry plants are separated and planted outdoors in autumn.
Propagate blackberries by lowering
A method for propagating blackberries with little effort is the formation of subsidence. For this purpose, long tendrils of the blackberry plant are ideally pressed to the ground about 30 to 50 centimeters below the shoot tip in April and weighted down with some earth and a stone or piece of wood. These sinkers should then usually develop roots by autumn and can thus be separated from the mother plant.
