Seedling
2-3 weeksThin green shoots emerge; small white roots establish. Seedlings are delicate and grass-like in appearance.
Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing once they reach 2-3 inches tall. Protect from strong winds.
Vegetative Growth
4-6 weeksGreen foliage expands; multiple thin leaves develop. Root system deepens and bulb formation begins underground.
Maintain consistent watering. Apply balanced fertilizer every 3-4 weeks. Mulch to retain moisture and suppress weeds. Monitor for early pests.
Bulb Development
4-6 weeksVisible swelling at soil line as bulbs expand. Foliage remains green and upright. Papery white skin forms on bulbs.
Continue regular watering but avoid overwatering. Ensure good drainage to prevent rot. Do not hill soil over bulbs. Light feeding if needed.
Maturation
2-3 weeksBulbs reach 1-2 inches in diameter. Tops begin to yellow, weaken, and fall over naturally.
Reduce watering as foliage dies back. Stop fertilizing. Do not bend over tops artificially; allow natural senescence. Monitor for rot.
Harvest & Curing
2-3 weeks curingTops completely dry and brown. Bulbs firm and papery-skinned. Roots dried and shriveled.
Harvest when 50-75% of tops have fallen over. Cure in a warm, dry, well-ventilated area for 2-3 weeks. Clean off soil gently; do not wash. Store in cool, dry location.

Harvest Tips
Harvest when bulbs reach 1-2 inches in diameter and 50-75% of tops have naturally fallen over, typically 90-110 days after planting. Gently lift bulbs with a fork, being careful not to bruise them. Cure in a warm (70-80°F), dry, well-ventilated space for 2-3 weeks before storage or pickling. Handle carefully as they bruise easily.
Fun Facts
- 🌱 Pickling Pearl was specifically developed in the Netherlands and Germany for commercial pickling operations, bred to produce uniform, small bulbs that pickle whole without cutting.
- 🌱 Pearl onions retain their white papery skin color and crisp texture better than other varieties when pickled, making them visually appealing and satisfying to eat.
- 🌱 Pickling onions are sweeter and milder than storage onion varieties because they are harvested younger and have less sulfur compound development.
