Onions are a staple in almost all vegetable gardens. One of the easiest way to plant onions is to use sets (teeny tiny onion bulbs you buy in the nursery). They are about the size of a marble. Plant them two inches in the ground when the temperature is about fifty degrees F. Choose a location that gets about seven hours of light every day. The bulbs can be planted about four inches apart.
Onions need to grow in firm soil. Tamp them down after planting. Mend the soil with: zinc, boron and nitrogen.
Onions are easily damaged by garden tools. You should mulch after the leaves start growing, or weed them by hand.
