Live in Minnesota and have the blackberries that bare on 2nd year canes. 2016 was 1st year they bore fruit and there were lots of canes produced so figured 2017 would be even better. All but 2 of the bushes are coming back this spring only from the roots. We did prune them last summer as they were taking over the area. Is it possible that this is winter kill or another issue?
