- Production: Each plant should produce about 10 eating size tubers (5-10cm across) and a few small ones. About 1 kg per plant.
- Planting: Planting 1st September gives you a harvest 1st Dec (98 days). Chit and replant immediately for a harvest in March/April, then another crop for July harvest if you have few frosts.
