Which gooseberry problems need quick action?
These spread or do lasting harm fast; check the plants and start treatment the day you see them.
- Grey mould: Small, almost translucent spots that turn brown and water-soaked; affected tissue goes soft, dark and dies, and buds and flowers shrivel.
- Honey fungus: Peel back the bark at the base — a creamy-white, paper-thin sheet of fungus between bark and wood that smells strongly of mushrooms confirms it; the bark at the base may crack and bleed.
