Seedling/Transplant
4-6 weeks from seed to transplant-ready sizeYoung plants with 2-3 leaves, thin and upright, establishing roots in soil
Keep soil consistently moist but not waterlogged. Protect from extreme temperature fluctuations. Harden off transplants before planting outdoors.
Vegetative Growth
6-10 weeksRapid leaf and root development; plants develop 4-6 green leaves, underground bulb begins forming
Maintain consistent moisture and regular nitrogen fertilization. Mulch around plants to retain moisture and suppress weeds. Monitor for pests and diseases.
Bulbing
4-8 weeksVisible swelling of the bulb underground as day length increases; leaves continue to grow but growth slows
Continue regular watering but begin reducing frequency as bulbs develop. Apply balanced fertilizer. Remove any flowering stems that appear.
Maturation
2-3 weeksBulbs reach full size; tops begin to yellow and fall over naturally, indicating the plant is pulling nutrients back into the bulb
Reduce watering significantly; allow soil to dry between waterings. Do not irrigate in the final 2-3 weeks before harvest. Avoid breaking or damaging foliage.
Harvest & Curing
2-3 weeks curingTops are 75-100% brown and fallen over; bulbs are firm with dry, papery outer layers
Gently dig bulbs to avoid bruising. Cure in a warm, dry, well-ventilated location (70-75°F, 60-70% humidity) for 2-3 weeks before storage.
Common Pests

Harvest Tips
Harvest in late spring or early summer (typically May-June in Georgia) when 75-100% of the tops have dried and fallen over. Gently dig bulbs rather than pulling to avoid damage. Leave 1 inch of stem attached and cure in a warm, dry, well-ventilated location for 2-3 weeks before storage. Properly cured Georgia Sweets can store for 3-4 months in a cool (45-50°F), dry location with good air circulation.
Fun Facts
- 🌱 Georgia Sweet onions are named after the Vidalia region of Georgia, which has unique soil and climate conditions that naturally produce sweeter onions with lower sulfur content than other varieties.
- 🌱 The sweetness of Georgia Sweets comes from naturally lower levels of sulfur compounds compared to storage onions; this also means they are more perishable and should be used within 3-4 months of harvest.
- 🌱 A single Georgia Sweet onion can weigh up to 2 pounds, and they are so mild that some people enjoy eating them raw like apples or adding thick slices to dishes without triggering tears from onion vapors.
