Ribes jostaberry

jostaberry

A cross between a gooseberry and a blackcurrant, combining the size of a gooseberry with the flavour of blackcurrant. The self-fertile bushes produce good crops of fruit that matures in July or August. You can eat fruit straight from the bush or use it in desserts and preserves. These deciduous bushes are vigorous and spineless.

How to grow

Cultivation

Jostaberries prefer a sunny site with well-drained but moisture-retentive soil, but will cope in most other soil conditions and tolerate light shade. Mulch annually with well-rotted manure or compost and apply a general purpose fertiliser in spring. Grow as blackcurrants so please see our blackcurrant cultivation page for more growing tips

Propagation

Propagate by hardwood cuttings in the dormant season

Suggested planting locations and garden types

Cottage and informal garden

Pruning

Prune when dormant in winter. Aim to keep an open centred goblet shaped bush, removing some of the older unproductive stems each year.

Pests

Diseases

Generally disease-free, resistant to gooseberry leaf spot and gooseberry mildew
