    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.

    Growing Onions


    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.

    Soil Preparation:

    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.
