Can blackberries be pruned now? They have stopped producing.
I have long shoots that will produce berries next year. It is these
long 5' shoots that I would like to cut back, hoping to encourage
more branches to shoot off from the base. Is now the time? JAN

I don't know when the best time to prune them is, but don't cut the new
shoots - take out the oldest ones. You cut the new ones, you won't have any
berries. You'll get more and more new shoots as the plant matures.
