Growing Notes

• Raise in late autumn for the local southern or central intermediate-day transplant slot; southern transplants generally run from July into early spring.
• Use raised, well-drained beds where winter soil stays wet.
• Sow 3 mm deep and thin wider for larger bulbs.
• Keep irrigation even through swelling, then reduce it as necks soften.
• Cure sound bulbs thoroughly before storage.

Seed safety: “Raw seed” describes the unpelleted sale form, not chemical-treatment status. Do not eat seed or use it for feed or microgreens; follow the physical lot label.
