Red Bull Onion serves as a versatile cooking onion, suitable for storage and long-term use in the kitchen. The bulbs can be used fresh in raw applications like salads and salsas, or cooked down into soups, stews, and caramelized dishes where their flavor develops over time.
Sow up to 10–12 seeds in a 4–6 inch pot. If seedling tops reach over 5 inches before transplant time, cut them back to 3 inches to encourage stronger root development.
When transplanting seedlings outdoors, carefully separate them and place in a shallow trench, then fill around the seedlings and water in well. Space them 2 inches apart in rows 12 inches apart.
Direct sow seeds and thin to the strongest plant when seedlings reach 4–5 inches tall. Space final seedlings 2 inches apart in rows 12 inches apart.
Harvest Red Bull Onion after about half the tops have naturally fallen over, typically around 110, 125 days from direct seeding. Once this happens, push over any remaining tops and wait about 1 week before harvesting. Lift bulbs carefully and begin the curing process immediately.
