Harvest Tips
Begin harvesting when white stems are 1/2-3/4 inch in diameter and 8-10 inches tall, typically 60-70 days from planting. Harvest by gently pulling entire plants from soil or cut stems 1-2 inches above soil line for repeated harvests. Outer leaves can be removed anytime while plant grows. Best harvested in morning for best flavor and crispness. Continue harvesting until frost kills plants or bolting begins.
Fun Facts
- 🌱 White Lisbon onions were developed in Lisbon, Portugal, and remain one of the most widely grown bunching onion varieties worldwide, prized for their reliability and mild flavor.
- 🌱 Unlike bulbing onion varieties, White Lisbon produces minimal to no bulb at the base, instead focusing energy on long, tender white stalks—making it a true 'scallion' rather than a storage onion.
- 🌱 These onions can be harvested multiple times throughout the growing season by either pulling the entire plant or cutting stems 1-2 inches above soil, allowing the plant to regrow for additional harvests.
