Which redcurrant problems need quick action?
These spread or do lasting harm fast; check the plants and start treatment the day you see them.
- Honey fungus: Branches die back over several years, or the whole plant dies suddenly in hot dry weather; leaves are smaller and paler, autumn colour comes early, and a last unusually heavy flowering or crop may come just before death.
