Seedling
2-3 weeksThin, grass-like green shoots emerge from soil; develops first true leaves
Keep soil consistently moist but not waterlogged; thin seedlings to proper spacing; provide bright light if growing indoors
Vegetative Growth
4-6 weeksMultiple thin green leaves develop; plant establishes shallow root system; bulb begins forming underground
Water regularly (1-1.5 inches per week); side-dress with balanced fertilizer at 4-6 week intervals; remove any flower stalks that emerge
Bulb Swelling
4-6 weeksVisible bulblets form at soil surface; white coloring becomes apparent; leaf growth slows as energy shifts to bulb development
Maintain consistent watering; avoid excess nitrogen which delays bulbing; mulch lightly around bases to keep soil cool and retain moisture; monitor for pests
Maturation
2-3 weeksBulbs reach full size (pea to marble-sized); tops begin yellowing and falling over naturally; outer skins papery and white
Reduce watering as tops fall; do not artificially bend tops over; stop fertilizing; harvest when 50-70% of tops have collapsed
Harvest & Curing
2-3 weeks curingBulbs dug and allowed to dry; papery skins develop protective layer; ready for storage and pickling
Cure in warm, well-ventilated location (70-75°F) for 2-3 weeks before storage; brush off soil gently; store in cool, dry place with good air circulation

Harvest Tips
Harvest when 50-70% of tops have naturally fallen over, typically mid to late summer depending on planting date. Grasp the base and pull gently when soil is slightly moist for easier removal. Cure bulbs in a warm (70-75°F), well-ventilated location for 2-3 weeks until outer skins are papery and completely dry. For pickling, harvest at the small pickling stage (pea to grape-sized) if preferred, though they can be grown to full maturity. Store in mesh bags or braided bundles in a cool (50-55°F), dry location with 60-70% humidity for up to 6 months.
Fun Facts
- 🌱 White Empress is sometimes called 'silverskin' or 'pearl onion' variety and has been cultivated for centuries specifically for pickling, with the practice dating back to medieval European food preservation.
- 🌱 These onions produce secondary bulblets (clusters) around the main bulb, allowing gardeners to harvest multiple small onions from a single plant for more intensive pickling operations.
- 🌱 The papery white skin contains a special protective compound that develops during the curing process, which is why proper air-drying is critical before storage and why they keep so much longer than larger onion varieties.
