Blackberry Pruning

Question

I have trained a wild blackberry over a bench arbour, and am getting promising fruiting this year. However there are also very very strong and vigorous but non fruit bearing arms; do i cut these back or let them be? Are they going to be the fruit bearing arms next year?

Answer 1

You will want to leave them alone for now. Those will be your fruit bearing canes next year.
