How do I grow Boysenberries
Posted by Dobies Staff on 05 December 2014 09:41 am

The Boysenberry is a cross between loganberry, raspberry and dewberry. The vigorous, drought tolerant plants are self-fertile producing large red fruits which ripen to dark red almost purple. Choose a position in full sun that is sheltered from cold winds. The soil should be well-drained, not too heavy, ideally slightly acid and rich in organic matter.

Prior to planting dig in plenty of well-rotted manure or garden compost and apply a general fertilizer such as Growmore. The plants will grow to a height of 2.4m (8ft) and will need some form of support. The canes can be tied to wires against a wall, fence or a trellis. Alternatively plant the boysenberries in an open space and tie the canes to wires strained between stout posts. If planting more than one plant space them 2.4m (8') apart. Keep the plants well watered in dry spells. As the canes develop they are tied into the support. The plant produces fruit from July to the end of August on the previous season’s canes. The fruit will need to be protected from birds.

Prune back the canes that have produced fruit to ground level as soon as possible after the crop has been harvested.

In March apply an annual mulch of well-rotted manure or compost to conserve moisture and keep down weeds along with a general fertilizer such as Growmore.
