Seedling/Transplant Establishment
2-3 weeksYoung onion sets or transplants develop root systems and initial leaf growth. Plants are small with minimal foliage.
Keep soil consistently moist. Thin seedlings to proper spacing if direct seeding. Provide gentle handling to avoid damaging tender plants.
Vegetative Growth
6-8 weeksPlants develop multiple green leaves and establish a strong root system. Foliage grows upright and becomes more robust.
Maintain consistent watering and provide balanced nitrogen-rich fertilizer every 3 weeks. Remove any flower stalks that appear. Mulch to retain moisture.
Bulb Development
4-6 weeksThe base of the plant swells as the bulb forms and expands underground. Foliage remains green but growth slows.
Reduce nitrogen; apply potassium-rich fertilizer to support bulb enlargement. Continue consistent watering but begin to taper as bulb matures. Keep weeds controlled.
Maturation & Dormancy
2-3 weeksBulbs reach full size and the papery outer skin develops. Foliage yellows and begins to dry and fall over (topple).
Reduce watering significantly once foliage falls over. Do not break or cut tops. Allow leaves to naturally yellow and dry. Stop fertilizing.
Harvest Ready
Ongoing harvest windowBulbs are mature with dry, papery skin and fully dried foliage. Plants are completely dormant.
Monitor for full dryness before harvesting. Gently lift bulbs and cure in a warm, dry, well-ventilated location for 2-3 weeks before storage.
