Do you cut back blackberry bushes in the fall?

How tall do blackberry bushes get?

3 to 4 feet tall
Blackberries grow into bushes 3 to 4 feet tall and wide. The roots of the plant are perennial, but the top is biennial; that is, a branch that comes up this spring will not fruit until next year, and after fruiting it will die. To maximize your berry harvest, you need to prune the shrub correctly.
