Care Essentials
- Feed with a balanced fertiliser at planting, then switch to high-potash feed once flowering begins. Avoid excess nitrogen which promotes foliage over fruit.
- Tomatillos need at least two plants for cross-pollination — a single plant will not set fruit. Harvest when the papery husk splits and the fruit fills it completely. Green varieties are used for salsa verde.
