Sprouting
1-2 weeksOnion sets or transplants send up thin, green shoots and begin developing roots
Keep soil consistently moist but not waterlogged; ensure good drainage to prevent rot
Vegetative Growth
4-6 weeksPlant develops multiple green leaves; foliage becomes more robust and upright
Maintain consistent watering; apply balanced fertilizer every 2-3 weeks; thin seedlings to proper spacing if needed
Bulbing
4-6 weeksBase of plant swells as the bulb forms underground; foliage remains green and actively growing
Continue regular watering; gradually reduce nitrogen fertilizer to encourage bulb development rather than leaf growth
Maturation
2-3 weeksBulb reaches full size; foliage begins to yellow and weaken; outer bulb skin becomes papery and golden
Reduce watering significantly; stop fertilizing; avoid disturbing the bulbs; ensure soil drains well to prevent cracking
Harvest
Harvest within 1-2 week windowFoliage has fallen over or dried; bulb is firm with dry, papery skin; ready for pulling
Harvest when 75% of tops have fallen over; cure bulbs for 2-3 weeks in a warm, dry, well-ventilated area before storage

Harvest Tips
Harvest when approximately 75% of the foliage has fallen over and turned brown, typically mid to late summer. Gently pull or dig the bulbs, being careful not to bruise them. Lay bulbs on the ground for a few days to cure in warm sun if weather is dry, then move to a warm, dry, well-ventilated location for 2-3 weeks to finish curing. Store in mesh bags or braids in a cool (32-40°F), dry place with good air circulation for up to 6-8 months.
