Planting & Care

For best results, start seeds indoors 8-10 weeks before the last frost date. Sow seeds ¼ inch deep in a seed-starting mix, keeping the soil moist but not waterlogged. Once seedlings are sturdy, harden them off and transplant outdoors after the danger of frost has passed. Space plants 4-6 inches apart in rows 12-18 inches apart. Onions require consistent moisture during the growing season; reduce watering as bulbs mature to encourage proper curing.

Utah Yellow Sweet Spanish Onions benefit from a sunny location and well-drained soil rich in organic matter. Fertilize lightly at planting and again when tops begin to grow vigorously. Keep the area weed-free to reduce competition. Harvest when tops begin to yellow and fall over; lift bulbs and allow them to dry in a warm, airy place before storing.
