Answer: All berries like attention, and, of course, they reward you well for it. Boysenberries, closely related to blackberries, have trailing vines that need to be supported on a wire trellis. Set the plants about 8 feet apart in rows and construct a 2- or 3-wire trellis with well-braced end posts about 25-30 feet apart and a post in the row between every 3rd and 4th plant. The first year, allow the canes to sprawl on the ground. The second year, loop them over the trellis, and after they have fruited, cut the canes close to the ground. Allow about 14 or 15 new canes to develop for the next year's crop and cut off the rest. Limiting the number of fruiting canes will encourage a better crop. Spread compost around the plants in the spring to conserve moistureand supply nutrients and organic matter.
