This article deals with Ribes rubrum, commonly termed Redcurrant (Red currant). Whitecurrant (White currant) refers to the same species, but only to cultivars with white-coloured fruit. Red and white currants are discussed in this article.
Blackcurrant refers to a different specis, Ribes nigrum, which is discussed in a separate article (See: Blackcurrant).
Problems
Birds: birds often feed on the fruit crop.[1] Redcurrants are a particular favourite of blackbirds in the UK.[2] Whitecurrants and late ripening redcurrant cultivars are eaten less by birds.[1] They may also damage buds. Nets can be used to cover the bushes over winter to prevent this.[3]
Aphids:[3] the Redcurrant Blister Aphid can cause large red "blisters" on the leaves of redcurrants in summer.[2] It can also occur on whitecurrants, with less frequency.[2] In blackcurrants this species of aphid causes yellow blisters.[2] The pale yellow aphid colonies are located on the undersurface of the leaves and appear in spring and early summer.[2] Plants should be checked regularly and sprayed with a organic control (see: Organic pesticides).[2]
