About Blackberry

Blackberries are vigorous perennial canes that produce prolific harvests once established. Thornless varieties exist for easier handling. Plants bear from the second year onward and can produce for 15-20 years.

Plant in full sun with a trellis or fence for support. Canes fruit in year two (primocanes grow year one, floricanes fruit year two). Prune out canes that have fruited. Thornless varieties like Triple Crown are much easier to manage.
