Redcurrants are planted as dormant, bare-root or container-grown shrubs in fall or early spring, and once established tolerate winter cold to about 14°F (-10°C). In the US, expect the berries to ripen over a roughly two-week window from mid-June to mid-July, turning bright red when fully ripe.

The short answer

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

Plan your Redcurrants planting

When to sow and plant Redcurrants depends on your own frost dates. Check the USA vegetable planting calendar. To work out where it fits in your beds, sketch your plot in the free Garden Layout Planner.

Frequently Asked Questions

What soil pH do redcurrants need?

A pH of about 6.5–7.5. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.

What problems affect redcurrants?

Our data links 4 diseases and 6 pests to this crop. See the sections above for each one and how to manage it.

Plan next season before the problems start

Almost everything on this page resolves to your own frost dates rather than the calendar — the last spring frost moves by roughly two months between zone 3 and zone 10. The USA Garden Planner works from your zone so the timing is already decided before the season starts.

Every growing guide is checked against RHS, USDA Cooperative Extension, and other named horticultural authorities before publishing. How we check our facts.

How this guide is put together

The growing data on this page — planting windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against USDA hardiness-zone and frost-date data, with Cooperative Extension sources cited directly where one exists for a crop. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
