About Onion White Seeds – Hybrid

White hybrid onion — white bulbs for both salad and cooking; a rabi season crop.

• Botanical name: Allium cepa
• Care level: Moderate
• Expected germination time: 8-15 days at 15-25C under suitable conditions*

How to Grow

1. Fill a seedling tray or small pot with a fine, clean, well-draining seed-starting mix.
2. Sow at the right depth — 1–1.5 cm in a nursery bed; transplant 6–8 week old seedlings.
3. Water gently with a spray bottle so the seeds are not displaced. Keep the medium moist, not waterlogged.
4. Place the tray where it gets the right light for this plant (full sun). Protect young seedlings from harsh afternoon sun.
5. Under suitable conditions, sprouts usually appear in 8-15 days at 15-25C.

Light, water, soil and feeding

• Light: Full sun
• Water: Keep moisture even while the bulb is forming; stop watering 2–3 weeks before harvest.
• Soil: Loose, well-drained loam with compost; pH 6.0-7.0
• Temperature: 13–25°C for growth. A short-day variety — bulbs form in India's normal rabi day length; the bulb matures as the heat rises.
• Fertiliser: Nitrogen 30 and 45 days after transplanting; once bulbing starts, stop nitrogen and give potash.

Sowing season in India

Nursery: Oct-Nov; transplant Dec-Jan (rabi). Exact timing depends on your local temperature and conditions.

Common problems

Thrips (white streaks on leaves), purple blotch in monsoon humidity, bulb rot from overwatering.
