About Onion

Onions are a staple crop that stores well and can be grown as sets transplants or from seed.

Growing from sets is easiest for beginners. Plant in early spring — onions are frost-tolerant. Day-length sensitive — choose short-day long-day or day-neutral varieties based on your latitude.
