I just purchased 6 Heritage raspberry plants in pots but am confused on pruning. It seems some of the comments are prune the brown cane this coming winter all the way to the ground leaving the new canes but other comments seem to suggest cutting the old cane down by 75%. Being totally new to this, can you clarify plus can you tell me if the plants should be fertilized and if so, what to use?
