White Snowball onion sets are a dependable and easy-to-grow option for gardeners seeking mild, sweet onions with fine-grained flesh and excellent keeping quality. This long-day variety is well-suited to northern and central climates, where extended daylight promotes firm bulb formation and crisp, clean skins.
This one has thin translucent white skins that are not noticeable, so there is less waste preparing the scallions for the kitchen. These sets produce medium-sized, flat onions with a delicate texture—ideal for pickling, fresh slicing, or adding to a wide variety of culinary dishes. Their mild flavor and tender bite make them perfect for fresh salads, cooking, or caramelizing.
Plant the sets 1 inch deep and about 4 inches apart in fertile, well-draining soil. White Snowball onions thrive in full sun, consistent moisture, and are hardy in USDA Zones 3–9. Their early maturity and reliable growth make them an excellent choice for spring planting, ensuring one of the first fresh harvests of the season.
This variety also stores well when properly cured, offering an extended harvest window and a pantry staple that lasts for months. Whether grown in rows, raised beds, or borders, these sets deliver dependable yields for growers of all experience levels.

Curing and storage
Because White Snowball is a long-day type, bulb formation is best where summer daylight matches its response. As tops fall, ease irrigation and lift the onions carefully. Cure in a shaded, dry, well-ventilated place until necks and outer skins are thoroughly dry, then trim and store only firm, undamaged bulbs. Compare other onion sets for different colors and regional day-length needs.
