How to Grow

Cultivation

Can be fan-trained to provide fruit, but more suited to a wildlife garden. Tolerates most soils and situations, but needs sun to flower and fruit well. May have the potential to become a nuisance if not managed well. See blackberry cultivation and brambles for more advice

Propagation

Propagate by seed or by tip layering, which it does naturally

Suggested planting locations and garden types

Wildlife gardens
Edible fruit

Pruning

Cutting out old canes, and shortening new ones, helps retain some measure of control but plants may need cutting to the ground every few years

Pests

Generally pest-free

Diseases

May be susceptible to grey moulds and honey fungus (rarely)
