New to growing Blackberries
I recently purchased a blackberry plant. When I purchased it from the nursery it was tied to 3 stakes in the center of the pot for support. I planted it as is and left the stakes in. Now there is one branch which has grown far out to the side and I think I need to trellis is.
My questions are, how exactly should I trellis it? Should I put something behind it to tie the branch to? Are tomato cages a good option? Should I remove the support that I planted it with?
I am also wondering about pruning. What do I cut back? Where do I cut it? And when? At the end of the season?
Any help would be greatly appreciated!!
