Keep apart or take care
- caution With Gooseberry: Gooseberry and redcurrant share American gooseberry mildew and currant aphids, so spread between neighbouring bushes is likely. Evidence B

Shared pests and diseases
- White pine blister rust: Alternates between five-needle pines and currants or gooseberries. Evidence B
