Stage BBCH Notes
Planting and establishment 0 Plant during dormancy, late autumn or spring; dig a hole twice the rootball's width and position the soil mark about 5cm lower than the surrounding soil, watering thoroughly afterwards (BBC Gardeners' World). Space plants about 1.5m apart with 1.8m between rows.
Vegetative growth 3 Vigorous, spineless deciduous growth, reaching about 1.5-2.5m tall and 1-1.5m spread (RHS). Mulch annually with well-rotted manure or compost and apply a general-purpose fertiliser in spring (RHS).
Flowering and fruit set 6 Self-fertile -- a single bush crops well, though cross-pollination from a different variety can increase yield (RHS).
Fruiting and harvest 8 Fruit ripens from light green through to dark reddish-black, ready to pick individually in late July to early August (BBC Gardeners' World; RHS). Protect from birds with reflective tape, CDs or netting.

Harvest & Storage

When to pick: Pick individually once fruit has turned dark reddish-black, late July to early August (BBC Gardeners' World). Eaten fresh or used in desserts and preserves (RHS); flavour is milder than blackcurrant, tasting more of gooseberry when underripe and more of blackcurrant once fully ripe.

Aves

Named directly by both RHS and BBC Gardeners' World as the main threat to ripening fruit -- reflective tape, CDs or netting recommended.

References

  1. Cross between blackcurrant and gooseberry. Soil: rich, moisture-retentive, not waterlogged. Full sun ideal, crops even with half-day sun. Plant dormancy (late autumn or spring), hole twice rootball width, soil mark 5cm below surrounding soil, space 1.5m apart with 1.8m between rows, water thoroughly after planting. Size: vigorous deciduous shrub to 2m x 2m. Pruning: winter dormant, reduce stems by half taking oldest wood right back to ground, remove low sideshoots, prune tips for accessible height. Pests/diseases: generally disease and pest free, resistant to leaf spot and mildew affecting gooseberries; birds need protection (reflective tape/CDs/netting). Harvest late July/early August, individually picked, dark reddish-black when ripe. Propagation: hardwood cuttings in dormancy, 15cm sections, 10cm deep.

  2. Deciduous, vigorous, spineless, 2-5yrs to maturity. Hardiness H5 (-15 to -10C). Soil: chalk/clay/loam/sand, moist but well-drained, acid/alkaline/neutral. Full sun or partial shade, south/east/west-facing, sheltered. Height 1.5-2.5m, spread 1-1.5m. Propagate by hardwood cuttings in dormancy. Pests: birds (fruit). Diseases: generally disease-free, resistant to gooseberry leaf spot and gooseberry mildew. Hybrid of gooseberry and blackcurrant, not native to GB/Ireland, family Grossulariaceae. Self-fertile, crops July-August, eaten fresh or in desserts/preserves. Grow as blackcurrants -- see blackcurrant cultivation page for more detail.

Plan next season before the problems start

Short-season growing is arithmetic before it is technique: days to maturity against frost-free days decides what will finish at all. The Canada Garden Planner does that subtraction for your region before you sow.
