i have some boysenberries that werent pruned last year, so they have growth that already fruited last year, overwintered canes with flower buds on them, and soon i expect there will be new canes coming up, if they arent already.
i know the canes are biennials. here is the question:
can i cut out the brown leafless canes [more like vines really] without worrying there might be nice green growth further along that same cane? for example, with garden roses, most nice green canes are emerging from a brown thicker cane close to the base of the plant, and if you cut off those brown canes in april, all you would have have is a 2" tall clump of stubs.
everything is tangled together, and i do intend to do a better job this season with two wires/tiers. i would like to cut out the brown sections if i wont wind up cutting off productive wood.
ps, i know boysenberries are inappropriate for my climate, but they dont know that. in fact, they want to take over a nearby raspberry row; i have to keep pruning them out of ground level of the raspberries where they are running along the soil surface.
