Growth Stages

1

Seedling/Sprouting

2-3 weeks

Thin green shoots emerge from sets or soil; tiny leaves develop

Keep soil consistently moist but not waterlogged; thin seedlings to proper spacing early; provide full sun exposure

2

Vegetative Growth

6-8 weeks

Multiple green leaves emerge forming a leafy crown; underground bulb begins to swell

Maintain consistent watering; apply 1-2 inches of mulch to retain moisture and regulate temperature; fertilize every 2-3 weeks with balanced fertilizer

3

Bulb Development

6-8 weeks

Bulb enlarges noticeably; outer skin begins to papery texture and whiten; foliage reaches full height

Continue watering until foliage begins to yellow; avoid excessive nitrogen which causes thick necks; monitor for pests and fungal issues

4

Maturation & Curing

2-4 weeks

Foliage yellows and falls over; bulbs stop enlarging; papery skin hardens; neck tightens

Reduce watering significantly; do not water after tops fall over; leave in ground for 1-2 weeks after toppling to allow skin to cure if weather permits

5

Harvest & Storage

Ongoing through storage

Bulbs fully mature with papery white skin; foliage completely dried and brown

Harvest when 50-75% of foliage has fallen over; cure in warm, dry, well-ventilated location for 2-4 weeks; store in cool (32-40°F), dark, humid (65-70%) conditions
