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
Dig tubers after foliage yellows and dies back; leave none behind unless you want the patch to regrow.
Important cautions
The plant spreads from missed tubers. The inulin-rich tubers can cause digestive discomfort, so introduce them in modest portions.
Plant guidance: P11a propagation, food-safety and plant-specific guide audit. Planting windows are a guide rather than a rule.
