Onions grow as layered bulbs that develop on top of the ground in between the roots and the green tops. For each leaf, a layer of the bulb is formed. The tops grow in cool weather, then as it warms, the bulbs begin to set. They’ll begin underground, and slowly push up through the soil as they mature.
