Answer: Wow! Canes that large must be producing great crops! With proper pruning, you should harvest berries every year. What you'd heard is partially true - it does take a cane two years to fruit. The first year, the canes are called primocanes, and in their second (and final) year, they flower and fruit, and are therefore called floricanes. You can prune the blackberry and raspberry canes that have fruited this year after the leaves fall. Also, thin the canes to 5-6 canes per foot of row. In late winter/early spring, before growth begins, remove 3-4" from the tips of the the remaining BLACKBERRY (only) canes (which will fruit that summer). They should grow lateral branches during the summer. Head these back to 8-12" for increased fruit production. Enjoy!
