Harvest Tips
Harvest when 50-75% of foliage has yellowed and toppled over (approximately 120-150 days after planting). Gently loosen soil and lift bulbs carefully to avoid bruising. Cure in a well-ventilated, shaded location at 70-75°F for 2-4 weeks until skins are papery and brittle. Trim roots to ¼ inch and remove dried foliage once completely dry. Store in cool (50-60°F), dry, well-ventilated conditions for 6-8 months.
