How do I prune a redcurrant — like a blackcurrant?

No — and this is the most important rule. Redcurrants fruit on spurs on a permanent framework of branches, so they're pruned like a gooseberry: open goblet shape, sideshoots shortened in summer and winter, only the oldest wood (4–5+ years) renewed. Pruning a redcurrant like a blackcurrant (hard to the base) removes the entire crop. Blackcurrants fruit on last year's wood, redcurrants on older wood — different plants, opposite pruning.

When are redcurrants ready to pick?

Late June to mid-July, depending on variety. The whole strig should be bright glossy red with no green or pink berries at the tip. Pick the entire strig by snipping the top stalk rather than individual berries. The flavour is sharp — high in pectin and acid, which is why redcurrant jelly sets beautifully and pairs so well with rich meats.

What's the best redcurrant variety for the UK?

Rovada — modern Dutch variety, very late (mid-July), the heaviest cropper, very long strigs, mildew-resistant. Red Lake is the traditional UK favourite — mid-season, reliable, large berries. Jonkheer van Tets for an early crop. For a mix, plant one of each to spread the picking from late June through July.

Why do my redcurrants not crop?

Three usual causes. Wrong pruning: someone has cut the bush back hard each winter, like a blackcurrant, removing all the fruiting wood. Switch to spur pruning and the bush will crop the following year. Birds eating the buds in winter: bullfinches strip the flower buds in February–March; net from December. Frost on flowers: late May frosts can knock out the crop in cold gardens; row cover the bush if a frost is forecast during flowering.

Can I grow redcurrants in shade?

Yes — better than most fruit. Redcurrants tolerate light shade and crop reliably even on a north-facing wall (fan-trained). Crop will be lighter and ripen a week or two later than in full sun, but flavour is fine. Useful for gardens running out of sunny corners.

How do I make redcurrant jelly?

Strip the berries into a pan with a splash of water, simmer until soft, strain through a jelly bag overnight, measure the liquid, add 450 g sugar per 600 ml liquid, boil hard for 8–10 minutes until it sets on a cold saucer. Redcurrants are so high in pectin you need no other gelling agent. A glass on a roast lamb sandwich is one of the great rewards of a UK kitchen garden.

Plant redcurrant bushes bare-root from November to March, in sun or light shade, in any decent garden soil — they crop heavily on a permanent framework of branches for 15+ years. Redcurrants are very hardy (RHS H6–H7) and shrug off any UK winter. Don't prune them like blackcurrants: redcurrants fruit on old wood and spurs, so train to a permanent open-goblet framework like a gooseberry. Net the ripening trusses heavily — blackbirds and squirrels strip a bush in a morning. Pick whole strigs (the strings of berries) by snipping at the top of the truss, then strip individual berries with a fork later. Jonkheer van Tets (early), Red Lake (mid), and Rovada (late, heaviest cropper) are reliable UK varieties.
