Onion Seeds

Useful gardening information

Onion is a cool-season vegetable that can be grown successfully throughout most of temperate North America. Onions may be grown from sets, transplants or seeds.

Onions form bulbs in response to daylength. When the number of daylight hours reaches a certain level, onion plants start bulbing, or forming bulbs. Long-day onions need about 14 to 15 hours of daylight to bulb. Short-day onions need 10 hours of daylight. Day-neutral onions form bulbs regardless of daylight hours and produce well in almost any region. As soon as daylength hits the 10-hour mark, a short-day onion starts forming a bulb. If the top of the plant hasn't had enough time to grow big and lush, the resulting bulb will be small. Conversely, if you live where daylength never hits 14 hours, long-day onions will never form a bulb. All you'll get are green leaves. By choosing the right type of onion for your region, you'll get healthy green stems that are large enough to fuel forming fat and tasty bulbs.

Generally speaking, long-day onions tend to do best in the North and short-day types tend to do best in the South. Growing onions from seed is often the only way to get varieties really suited to your location. Intermediate onions are for middle regions between north and south. Day neutral onions will grow about anywhere as will almost all bunching onions. High temperatures and low humidity are advantageous during bulbing and curing. Onions have shallow roots and compete poorly with weeds and grasses. Timely shallow hoeing and cultivation are important, especially when the onions are small.
Onions may be eaten raw, broiled, boiled, baked, creamed, steamed, fried, french fried and pickled. They are used in soups and stews and combination with vegetables and meats.
