Plant in a soil enriched with compost and well-rotted manure. Water newly established plants regularly, especially during dry weather. Allow soil to dry a little in winter as plants dislike waterlogging. Established plants can be pruned in winter, removing any old wood. red currants should be pruned to an open vase shape, like plums, for optimal cropping, although this does also make it easier for birds to steal your crop. Top-dress the root zone in spring with compost.
