How to Grow Blackcurrant
Bush Berry
Blackcurrants are productive, aromatic bushes that earn their space in a British fruit garden. They crop reliably in sun or light shade and their berries suit simple kitchen use. Compact 'Ben' varieties, including 'Ben Sarek' and 'Ben Connan', are especially useful where space is limited.
Planting
Plant bare-root bushes from November to March, setting them about 1.5 m apart, or plant container-grown specimens at other workable times. Set plants 5 cm deeper than their nursery level to encourage new basal shoots. Firm the soil, water well and mulch with garden compost. A bush normally needs no support, though a simple hoop or low frame can prevent heavily laden branches resting on soil. Keep the root area free from competing grass and weeds.
Care & pruning
Blackcurrants fruit on young wood. Each winter cut a third of the oldest stems cleanly to the base, favouring strong new shoots to replace them. Remove weak, damaged and crowded growth, keeping the centre open. Mulch annually with garden compost and use an organic fertiliser in spring where needed. Water regularly during dry weather from flowering until harvest. Do not summer-prune heavily, as this can remove useful replacement growth.
Harvest
Harvest from early July to August, when whole strings are glossy black and berries come away easily. Pick complete strigs rather than individual berries where possible. Fruit is often sweetest after a few dry, warm days, but harvest promptly once ripe to limit losses to birds.
Common problems
Blackcurrant big bud mite produces unusually swollen, rounded buds and can spread reversion virus. Buy certified stock, pick off and destroy affected buds, and remove severely affected bushes. Aphids, leaf spot and powdery mildew may occur; encourage predators, improve air circulation and clear fallen leaves. Net ripening fruit against birds, ensuring nets are taut and checked regularly.
