Red Currant in October: monthly care

Red currants thrive in full sun or partial shade, though a sunnier position will give you sweeter, more abundant fruit. They tolerate a wide range of soils but perform best in moisture-retentive loam or clay that doesn't dry out in summer. Avoid very light, sandy soils unless you're prepared to water and mulch regularly. Plant bare-root red currants between October and November or in March, when the soil is workable and not frozen or waterlogged. Container-grown plants can go in at any time during the dormant season, but autumn planting gives roots time to establish before spring growth begins. Space bushes 120 cm apart to allow good air circulation and room for picking. Dig a hole roughly twice the width of the root ball and deep enough so the old soil mark on the stem sits level with the surrounding ground. Red currants are usually grown as open-centred bushes on a short leg (a clear stem of about 10–15 cm), so don't plant any deeper than the nursery level or you'll encourage suckers from below the graft or leg. Fork over the base of the hole and mix in a bucketful of well-rotted compost or manure to improve moisture retention. Backfill with the excavated soil, firming gently with your heel to eliminate air pockets. Water thoroughly after planting, even in autumn, to settle the roots. Apply a 5–8 cm layer of organic mulch such as garden compost or well-rotted manure around the base, keeping it a few centimetres clear of the stem to prevent rot. Stake young bushes if your site is exposed to wind.

Red currants need consistent moisture, especially from flowering in spring through to harvest in summer. Water regularly during dry spells—aim for a thorough soak once or twice a week rather than frequent shallow watering. Mulch helps enormously: top up the organic layer each spring to suppress weeds, conserve moisture, and feed the soil as it breaks down. Feed in late February or March with a balanced general-purpose fertiliser (such as blood, fish and bone) or a controlled-release granular feed, scattering a couple of handfuls around the base of each bush and lightly forking it into the soil surface. Avoid high-nitrogen feeds later in the season, as these promote soft growth at the expense of fruiting and winter hardiness. On poorer soils, a second light feed after harvest can help the plant build reserves for next year. Red currants are fully hardy and need no winter protection in temperate Europe. They flower early, so in frost-prone gardens consider draping fleece over bushes on cold spring nights to protect the blossom and ensure a good set of fruit. Watch for aphids on shoot tips in spring and early summer; squash small colonies by hand or spray with an insecticidal soap if numbers build up. Gooseberry sawfly caterpillars can strip foliage rapidly—check the undersides of leaves from late spring onwards and pick off by hand or use an organic contact spray. Powdery mildew and leaf spot occasionally occur in humid conditions; good pruning for airflow and avoiding overhead watering reduce the risk. Birds are the main harvest pest—net bushes as the fruit begins to colour if necessary.
