Growing Instructions

• Sowing time: August is ideal for direct sowing in the ground or seed trays. If using trays, transplant seedlings to their final position by early October.
• Planting depth: Sow seeds approximately 0.5 inches (1.25 cm) deep.
• Spacing: Allow 18 inches (45 cm) between rows and 5 inches (12.5 cm) between plants.
• Soil: Thrive in fertile, well-drained soil enriched with compost.
• Watering: Maintain consistent moisture, especially during dry periods. Avoid overwatering, which can lead to rot.
• Thinning: Once seedlings reach 6 inches (15 cm) tall, thin them to ensure optimal spacing and bulb development.
• Harvesting: Ready for harvest when the tops turn brown and dry, typically in June or July.
• Storage: Store onions in a cool, dry place for several months.
