Pruning of a raspberry plant
I grew a raspberry plant in a container. The plant grew nicely and was bushy but yelled only a couple of berries. I thought I did the right thing by cutting all branches down to one inch after the first frost. Did I ruin, kill, the plant? If not, what do I do with the plant over the winter. I live in northern IL.
Some raspberries need to be pruned very carefully depending on when they bear fruit. It is also worth noting that raspberries, unless meant as a container variety, do very, very poorly in container. To maintain them in this fashion is enough to drive one crazy. If you want to continue to raise this plant in container, then I would go no less than about 8 gallons of soil.
