My daughter and I grow Bristol Black raspberries, Latham raspberries, and Wild black berries that she transplanted from the wild. Also Blueberries. Attached picture is the Blueberry raised bed. 3rd year. (After pruning)
I regularly apply a layer of used coffee grounds on the surface every early spring. They seem to love it.
They do like the soil more acid than normal. I think this helps, but I apply additional acidification.
I always prune the berries every late winter/early spring. That was done 2 weeks ago.
We fertilize with liquid fish fertilizer diluted as per instructions and it seems to work very well.
