How to Sow and Plant
+
Sow Tropea onion seeds indoors from July to October in well-drained, nutrient-rich soil. Start seeds in seed trays or pots, keeping the soil moist and warm. After seedlings develop, transplant them outdoors from July to October, spacing plants about 10-15 cm apart in rows enriched with compost. Choose a sunny location with loose soil to support healthy root development. For outdoor sowing, sow seeds directly in prepared rows during the same period, covering lightly with soil. This method ensures strong establishment and an excellent foundation for the onion’s distinctive sweet flavor and shape.
Tropea onions thrive in warm, well-drained soil with ample sunlight, ensuring their characteristic sweetness and elongated shape. Regular watering supports steady growth, but avoid waterlogging to prevent bulb rot. Applying balanced fertilizer enhances nutrient uptake, promoting vibrant, healthy bulbs rich in vitamins. Mulching helps retain moisture and suppress weeds. Harvest between March and August when bulbs reach full size and the tops begin to yellow. Their mild flavor is at its peak when allowed to mature fully, though they also offer a tender taste when picked younger for versatile culinary uses.
