Black Currant

Growing

When planting blackcurrants, plant in autumn or winter to establish a strong root system. For young bushes, a severe initial prune is necessary. Cut all shoots back to two buds above the soil line so the plant establishes before it fruits. As the shrub matures, maintain productivity by thinning out old, unproductive wood and removing weak or sideways-growing branches that might sag under the weight of the harvest.

Choose varieties resistant to white pine blister rust, such as 'Titania', as many traditional strains are susceptible. The bushes are hardy, but late spring frosts during flowering can reduce the crop. Also check the leaves for the currant borer, which causes shoots to wilt and die, and the blackcurrant gall mite, which causes "big bud" swelling in the winter.

Harvest the glossy black berries by hand once they are fully ripe. The berries do not ripen once off the vine, so pick them at their peak. Avoid washing them before storage to prevent spoilage. Keep the harvest in the fridge for short-term use, or freeze, dry, or can it for longer-term preservation.
