Onions respond to changing day length. Grow short-day varieties in southern latitudes. Long-day varieties work best in northern areas. Try growing different varieties from seed to explore differences in bulb color, size and shape.
Harvest young onions as scallions. When bulbs form and the tops of the plants fall over, pull them and cure in a warm place for about 10 days before storing.
Weed early and often to keep onions growing strong. Seedlings are less likely to bolt (produce flowers) compared to bulb onions grown from sets.
