These onions develop their signature mild sweetness precisely because they're so well-suited to consistent watering and rich soil. The white skin isn't just attractive; it signals a thin, tender papery layer that forms as the bulbs mature and cure. Plant them 2 inches apart in rows 12 inches apart, keep the soil consistently moist through the growing season, then deliberately withhold water as they approach maturity to encourage that protective paper to form and cure properly.
These onions shine in fresh applications where their mild, sweet character can take center stage. Slice them thin for salads, dice them for salsas, or caramelize them slowly to deepen their natural sweetness in soups and sauces. Their tender texture also makes them excellent for pickling and for gentle cooking methods where you want the onion's delicate flavor to complement rather than dominate.

Sow seeds indoors in a 4, 6 inch pot, placing up to 10, 12 seeds per pot. Seeds germinate between 50, 70°F. If seedling tops reach over 5 inches before transplanting, cut them back to 3 inches to encourage stronger root development before moving outdoors.
When seedlings are ready, carefully separate them and plant in a shallow trench outdoors. Space transplants 2 inches apart in rows 12 inches apart. Fill the trench around seedlings and water in thoroughly to establish good soil contact.
Direct seed outdoors when soil temperatures reach 50, 70°F. Thin seedlings to the strongest plant when they reach 4, 5 inches tall, spacing final plants 2 inches apart in rows 12 inches apart.
Harvest White Bermuda Onions after approximately 95 days when roughly half the tops have naturally fallen over. After the tops fall, push over any remaining green tops and wait about one week before harvesting. Harvest in dry weather; onions picked in wet conditions cure poorly and are prone to rot. Once harvested, loosen the soil around bulbs to encourage drying and curing before storage.
