Stage BBCH Notes
Planting 0 Best planted September/October or April/May, propagated by hardwood cuttings taken in autumn (RHS).
Establishment 3 Mulch with well-rotted compost, manure or bark, especially on dry soils; water regularly if container-grown (RHS).
Flowering and fruiting 6 Produces hanging clusters of shining red berries, attractive to pollinators when flowering (RHS).
Mature shrub 9 Reaches full maturity over a notably long 5-10 years, 1.5-2.5m in height, 1-1.5m spread (RHS).

Harvest & Storage

When to pick: USU: "Currants ripen over a two-week period in mid-June to mid-July...and change color to a bright red when fully ripe"; fruit "do not need to be harvested as soon as they turn red, as they hold well on the plant"; leaving fruit 2-3 weeks after coloring "will enhance flavor and sweetness"; harvest "the whole cluster at once" since the tender skins tear easily; yield "about 3 to 10 pounds per bush". RHS: protect ripening fruit from birds with netting or a fruit cage.

Storage

Best used fresh or for jams/juice; tender skins tear easily so handle by the cluster

Frequently Asked Questions

When should I sow redcurrants in the UK?
