Customer Reviews
The plants arrived in good condition but I was in the hospital for a while and three of them didn't make it.
I will definitely replace them when I can.
Great company to work with.
I purchased 2 plants that were delivered by transit. Upon arrival, one looked good having green leaves and the other had some brown leaves, so I was concerned. I grow other berries and I know they are usually hearty plants. Once in the ground and cared for by directions included, they have thrived. They are now about 3-4’ high. No berries yet, but I do not expect them this year. I am pleased and look forward to next years harvest. Thank you Territorial Seed.
Disappointed. Very small and fragile, one (1) died, never grew, the second plant is very small, and hasn't grown any new leaves yet, but getting a tiny bit bigger. No berries this year, and hoping they are truly thornless
So sorry to hear that! The plants should arrive in a dormant state, not dead. They are 1 year old at time of shipment and won't produce any fruit until at least their second year. Please reach out, so we can help troubleshoot or figure out if we need to issue a refund.

I purchased this item two summers ago. The first year it established well in a large pot and this year it is bursting with many many flower buds so far. Many fruits to come. Very happy with this purchase.

Initial Instructions
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.
Fertilizer
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.
Cultivation
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.
Pollination
Boysenberries are self-fertile.
