Do blackberry plants spread?

Do blackberries grow on new or old growth?

Blackberries only produce fruit on canes that are two years old, so once a cane has produced berries, it will never produce berries again. Cutting these spent canes off the blackberry bush will encourage the plant to produce more first year canes, which in turn will mean more fruit producing canes next year.
