How to Grow Boysenberry
Rubus ursinus × idaeus
Boysenberries are trailing cane fruits trained on wires, producing large dark purple berries with a rich sweet-tart flavour in mid-summer. Excellent fresh or for jam and pies. Prune after harvest by removing fruited canes and tying in new growth. Feed in spring and water well during fruiting. Net against birds as fruit ripens.

Train on wires
Tie trailing canes along horizontal wires, keeping new and fruiting canes separate for easy management after harvest.
Pick when very dark
Harvest when berries are deep purple-black and very soft. They are fragile and don't store well, so eat or process quickly.
Remove old canes promptly
Cut fruited canes to the ground immediately after harvest. This reduces disease and gives new canes more light.
Protect from birds
Net the plant as fruits begin to colour. The large sweet berries are irresistible to birds.
