Getting started
Plant firm, disease-free tubers in the recorded window and allow enough room for the underground crop to develop.
The right conditions
Choose a position with good light, fertile free-draining soil and protection from harsh heat; provide winter chill where the crop requires it.
As it grows
Water consistently while establishing, mulch without burying the crown or stem, manage weeds early and provide support where the mature habit needs it.
Ready to harvest
Lift tubers after frost or shortening days have killed back the tops; cure briefly in light if a sweeter flavour is wanted.
Important cautions
Tubers are the edible part. Some cultivars contain more oxalate; cooking and normal culinary portions reduce concern.
Plant guidance: P11a propagation, food-safety and plant-specific guide audit. Planting windows are a guide rather than a rule.
