Yes.

Feeding

Drench with a liquid organic fertilizer when plants show rapid new growth in spring. Keep the root zone mulched to retain moisture.

Spacing

Single Plants: 2' 11" (90cm) each way (minimum)
Rows: 2' 11" (90cm) with 2' 11" (90cm) row gap (minimum)

Sow and Plant

Set out purchased plants in mid-spring, or root stem tip cuttings from an established plant. Protect young plants from nibbling by deer with a wire cage. Like other brambles, boysenberries grow new stems which fruit in their second year and then die. Boysenberries are a complex cross between upright raspberries and trailing blackberries. A trellis helps control the growth of the large, vigorous plants, and makes the fruit easier to pick.

Notes

Use a trellis to so you can train plants into a dense, head-high hedge.

Harvesting

Boysenberries are ripe when the fruits turn from red to a deep red-black color. Harvest in the morning, while the fruit is cool, and refrigerate immediately. Boysenberries can be frozen or made into delicious jams and desserts.
