Planting & Care

Sow seeds indoors 8-10 weeks before transplanting, or direct sow in fall in mild climates. Plant seeds 1/4 inch deep in a well-drained seed-starting mix. Keep soil consistently moist but not waterlogged. Once seedlings emerge, provide bright light and thin to 2-3 inches apart. Transplant outdoors after hardening off, spacing plants 4-6 inches apart in rows 12-18 inches apart.

Onions require regular watering and benefit from a balanced fertilizer. Stop watering as bulbs mature to encourage curing. Harvest when tops fall over and begin to dry. Cure bulbs in a warm, dry, well-ventilated area before storing.
