Seedling
10-14 daysTiny green shoots emerge from soil with thin, grass-like leaves. Plants are fragile and vulnerable to drying out.
Keep soil consistently moist without waterlogging. Provide bright light if growing indoors. Thin seedlings to prevent competition when 2-3 inches tall.
Vegetative Growth
25-35 daysPlants develop multiple thin, upright green leaves forming clumps. Root systems establish and bulbs begin to swell underground. Foliage may reach 8-12 inches tall.
Maintain consistent moisture and regular watering. Apply balanced fertilizer every 3-4 weeks. Weed regularly to reduce competition. Mulch lightly around plants to retain moisture.
Bulb Development
20-30 daysSmall white bulbs form and enlarge underground while foliage continues to grow. Bulbs remain mild and tender at this stage with very thin papery skin developing.
Continue consistent watering and fertilizing. Do not hill soil over bulbs as this can inhibit proper bulb formation. Monitor for bolting and remove any flower stems immediately.
Maturation
7-14 daysBulbs reach 1-1.5 inch diameter; tops begin to yellow and weaken, eventually falling over naturally. Papery white skin tightens around bulb.
Reduce watering as tops dry down. Do not break or bend tops prematurely as this may trap moisture and cause rot. Wait for natural senescence before harvesting.
Harvest & Storage
Variable, harvest at peak readinessTops are completely brown and dry; bulbs are fully cured with papery skin intact. Plants are ready for lifting and storage.
Harvest on a dry day. Gently loosen soil and lift bulbs. Cure in a warm, airy location for 2-3 weeks before storage. Store in cool, dry conditions for 6+ months.

Harvest Tips
Harvest when tops naturally fall over and dry to brown, typically 60-75 days after transplanting. Gently dig to avoid bruising delicate bulbs. Cure in a warm (70-80°F), dry, well-ventilated location for 2-3 weeks before storage. Store in a cool (50-60°F), dry place in mesh bags or open containers for 6+ months. For pickling, harvest at peak size (1-1.5 inches) to ensure uniform, whole bulbs for preservation.
