Plant onions in the early spring around March or April when the temperature is still cool.
Plant onions in a location where they can receive plenty of sunlight. As a general rule of thumb, onions need about six hours of sunlight per day. Make sure that the location has plenty of well-drained, loamy soil.
Before planting, mix the soil with a layer of manure or fertilizer. Nutrient-rich soil is critical to the development of onion plants.
Purchase onion sets, which look like tiny bulbs. Plant them in a one-inch hole. Space each plant 12 to 18 inches away from each other.
Fertilize the onions regularly until the bulbing process starts. This occurs when the onions grow large enough to push above the soil line.
Mulch the plants to keep weed growth down and the soil moist.
Give the plants one inch of water per week.
