Onions are easy to grow from home from seed for anyone.  Many claim that starting from seeds produces larger fruits than starting from sets.  You want well draining but fertile soil, amended with compost.  Plant seeds indoors 8 weeks before the average last frost date and transplant outside just before the last frost.  Plant seeds ¼ inch deep.  Make sure to harden off the seedlings before transplanting outside in the garden. Transplant the seedlings about 2-6 inches apart in rows 12 inches apart.  Take care to not bury the seedlings too deep to help encourage large root growth. Onions are cold hardy.  Harvest when the tops turn yellow and fall over and store in a root cellar through the winter.  Specific harvest date will depend on variety.
