How do I grow Onions from seed?

In order to grow Onions from seed, you need to start them indoors 8–10 weeks before the last frost date. Use a high-quality seed-starting mix and keep the soil consistently moist until germination. Once seedlings are several inches tall, harden them off and transplant outdoors in rich, loose soil with full sunlight. Space plants evenly to allow bulbs to expand. Water regularly but avoid overwatering, as soggy soil can cause rot. Harvest when the tops fall over and dry, then cure onions in a warm, airy place for long-term storage.
