After unpacking, allow the plant a few days to gradually acclimate to its full exposure. Plant your boysenberry in an area with well-drained, not soggy soil that’s enriched with humus. Initially, apply ½ cup of Territorial’s Complete Fertilizer per plant mixed into the bottom of the planting hole, backfill around the plant and water well. Boysenberries appreciate a minimum of ½ day of sun to full sun for best production.
In years to follow, apply ¼ pound of Territorial’s Complete Fertilizer per plant in the spring (before growth starts) and again in May. Maintain good weed control. If using mechanical weed control do not work soil very deep as boysenberry roots are shallow.
Boysenberries are generally vigorous growers and require support to hold up the plants. A trellis or fence at least 4-5 feet tall should provide adequate support. Our boysenberry produces fruit on the 2nd year old canes. After fruiting, the cane will die, and you can prune it back to the ground. In spring, prune the canes to about 5 feet tall to encourage lateral branching and produce more fruit. Keep the soil moist for the first year to establish the plant.
Boysenberries are self-fertile.
