Garlic rarely produces seed, so the main bulb must be separated into small cloves to increase plantings. Plant in early spring or fall, setting cloves 4 inches apart and 1 inch deep in moderately fertile soil and full sun. In rich soil, garlic develops more top vegetation and fewer bulbs. Harvest bulbs after the tops have yellowed. Cure in the sun for 2 weeks or until dry. Place in mesh bags and hang in a cool, dry, dark room. Replant bulbs in September for the following year.
