Giant Onion Seeds themselves are small but can be used to grow giant onions. You can plant them in well-draining soil in the spring, after the last frost. They require full sun exposure and regular watering to thrive.
Highlights:
- Product Type: Bonsai
- Full-bloom Period: Summer
- Size: Small
- Quantity: 100 pieces
- Soil requirements: Giant onions 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: Giant onions need consistent moisture, especially during the growing season. 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 giant onion seeds is in early spring, as soon as the soil can be worked. In warmer climates, they can also be planted in late 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 room for the bulbs to grow.
- Germination time: Giant onion seeds typically germinate within 7-14 days under optimal conditions.
- Maturity time: Giant onions usually take about 100-120 days to reach maturity from the time of planting.
- Harvesting time: The best time to harvest giant onions is when the tops begin to yellow and fall over, usually in late summer to early fall. Harvest in the early morning or late afternoon to avoid the heat of the day.
- Harvesting tips: Use a garden fork to gently lift the onions from the soil. 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.
