Blackcurrant Plant Care

Blackcurrant (Ribes nigrum) belongs to the Grossulariaceae family within the Ribes genus. Blackcurrant is native to temperate parts of central and northern Europe and northern Asia. Blackcurrant is also known as Black Currant.

Blackcurrant displays an upright, spreading shrub growth habit, reaching up to 6 ft tall with a spread of approximately 8 ft. Blackcurrant produces small clusters of greenish to reddish flowers.

Leaf size: approximately 3 inches.

Water a young or newly planted Blackcurrant every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Blackcurrant thrives in full sun to partial shade.

Ribes nigrum tolerates temperatures of 60–90°F. Blackcurrant prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Blackcurrant to prevent waterlogging, which leads to root rot and fungal issues.

Feed Blackcurrant every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Blackcurrant is suited to USDA Zone 2a – 7b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Blackcurrant can spread to about 8 ft (2.4 m) and reach about 6 ft (2 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Blackcurrant while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Blackcurrant is hardy down to USDA zone 2a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Blackcurrant can be propagated through softwood cuttings, hardwood cuttings, layering. Similar propagation techniques also apply to mapleleaf currant plant care, which shares the same genus.

Blackcurrant is susceptible to aphids, currant borer, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Blackcurrant grows outdoors in USDA Zone 2a – 7b. It survives winters down to planting zone 2a. Blackcurrant is native to temperate parts of central and northern Europe and northern Asia.
