Rich soil with compost dug in. pH of 6 to 6.5 preferred.
White currants grow best in locations that receive morning sun and afternoon shade, or dappled shade part of the day.
Many cultivars are hardy to -40F (-40C). These cold-natured plants seldom produce well in warmer climates where temperature often top 90F (32C).
Fertilize in late fall by spreading a 1-inch (2.5 cm) layer of composted manure over the root zones of the plants. Slow-growing plants can be fed again in early summer.
Single Plants: 2′ 11″ (90cm) each way (minimum)
Rows: 2′ 11″ (90cm) with 2′ 11″ (90cm) row gap (minimum)
Sow and Plant
Plant in spring, just as the plants are emerging from dormancy. Set plants slightly deeper than they grew in their nursery pots. Mulch after planting to keep the soil cool and moist.
Powdery mildew can be a serious problem for white currants, so consider planting resistant varieties such as ‘Blanka’ or ‘Pink Champagne’. In winter, prune out old branches close to the ground. Mature white currants bear best on two-year-old branches.
Harvest fruit when the fruits just begin to soften, and chill immediately. White currants freeze very well.
