Onions are a cool-season biennial that prefers full sun and fertile, well-drained soils. One cup of raw chopped onions is very low in saturated fat, cholesterol and sodium. It is also a good source of dietary fiber, Vitamin B6, Vitamin C and Folate.
Evergreen White Bunching is a good, mild green onion. Utah Sweet Spanish, Fiesta, Wall-Walla and Sweet Sandwich are all excellent bulb onions. Many of these varieties come as seeds, sets or transplants.
Onions will grow in all soil types provided they are rich, well drained, moist, and fertile. Before planting, incorporate 4-6 inches of well-composted organic matter and 1-2 lb of all-purpose fertilizer (16-16-8) per 100 square feet. Work compost and fertilizer into the soil to a depth of 6-8 inches.
