- Soil requirements: White onion heirloom seeds prefer well-drained, fertile soil with a pH level between 6.0 and 7.0. The soil should be rich in organic matter and have good moisture retention capabilities.
- Sunlight needs: These seeds require full sun exposure, which means they need at least 6-8 hours of direct sunlight per day.
- Watering requirements: White onions need consistent moisture, especially during the bulb formation stage. Water them deeply once a week, ensuring the soil remains moist but not waterlogged. Mulching can help retain soil moisture.
- Planting season: The best time to plant white onion heirloom seeds is in early spring or late summer. In regions with mild winters, they can also be planted in the fall.
- Depth and spacing: Plant the seeds about 1/4 inch deep and space them 4-6 inches apart in rows that are 12-18 inches apart. This spacing allows for adequate air circulation and growth.
- Germination time: White onion seeds typically germinate within 7-14 days under optimal conditions.
- Maturity time: White onions usually take about 100-120 days to reach maturity from the time of planting.
- Harvesting time: The best time to harvest white onions is when the tops begin to yellow and fall over, usually in late summer or early fall. Harvesting is best done in the early morning or late afternoon to avoid the heat of the day.
- Harvesting tips: Gently lift the onions from the soil using a garden fork or spade. Allow them to cure in a warm, dry, and well-ventilated area for 2-3 weeks before storing. Store the cured onions in a cool, dry place with good air circulation to prevent rot.
