Allium cepa onion
|Easy to grow, edible members of this diverse family include Onions, Garlic, Shallots, Leeks, Green Onions and Chives. Leaves grow best in cool weather and moist soil. Mature Onions, Garlic and Shallots form bulbs in summer. Feed early in growing season with low nitrogen, high potassium and phosphorus fertilizers. Slower grown from seed, but you will get a larger crop and more varieties to choose from. Easiest to grow from small bulbs called sets. In mild winter areas, plant in fall. Elsewhere, plant in earliest spring. Store Garlic bulbs and Onions in a cool, dry, airy place out of direct light.
Of white, yellow, and red onions, red are sweetest. Start from sets or transplants. Bulbs form according to day length. In warm winter areas, plant 'short day' onions in fall for early summer crop. In northern areas, plant 'long day' varieties in spring. When leaves begin to yellow, bend stems to ground. When fully yellow, dig up onions. When leaves turn brown, cut tops to 1 inch, and keep onions in a dry, shady spot for a week. Spanish and Bermuda Onions do not store well.
