Red, White and Black Currants
These delicious fruits need moisture-retentive soil, and those in pots must be watered regularly during the growing season. Plant them in large containers filled with soil-based potting mix, combined with well-composted organic matter garden compost or bagged manure is ideal. You can either grow them as bushes or train them on a trellis like a climber. Apply a general fertilizer for fruit crops in spring, and top up with tomato fertilizer every week from late spring until the fruits ripen. Cover the blooms with plastic sheeting if frosts are forecast. Site in a cool, partly shaded spot. For pruning, see gooseberries (next).
