Getting started
Sow seed in the recorded five-zone window. Use clean seed and follow the packet's depth and spacing for the named species or cultivar.
The right conditions
Choose the light, drainage and soil fertility suited to the crop; match watering to the climate and avoid prolonged waterlogging.
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
Pick unsprayed petals when fresh; lift sound tubers after top growth dies back if using a known edible cultivar.
Important cautions
Edibility and flavour vary by cultivar. Use unsprayed petals or sound tubers only after positive identification; discard bitter or damaged material.
Plant guidance: P11a propagation, food-safety and plant-specific guide audit. Planting windows are a guide rather than a rule.
