Cultivation Guidelines
1. Sowing Time – Choose according to local climate and farming practices.
2. Seed Preparation – Soak in warm water for 6-12 hours, then sprout under ~25°C before sowing; direct sowing is also possible.
3. Soil Requirements – Fertile, loose, well-drained loam or sandy loam; apply basal fertilizer before planting.
4. Fertilization – Use potassium sulfate-based fertilizers; avoid excessive nitrogen, chloride, or nitrate fertilizers to prevent bolting or malformed bulbs.
5. Watering – Maintain consistent soil moisture, avoiding both drought and overwatering.
6. Seedling Care – Thin and replant seedlings for even growth; protect from pests and diseases.
7. Harvesting – Collect bulbs at proper maturity to ensure both yield and quality, avoiding cracking or storage loss.
