Grow Crisp and Flavorful White Snowball Onions in Your Garden

Introducing White Snowball Onion Sets, your gateway to cultivating crisp, mildly sweet onions perfect for a variety of culinary delights. These versatile onions enhance salads, sandwiches, and salsas with their fresh flavor and fine-grained texture. Easy to grow and boasting excellent storage potential, they're an ideal choice for both novice and seasoned gardeners.

Product Features:

  • Flavor: Mild and slightly sweet, making them perfect for both raw and cooked dishes.
  • Hardiness Zone: Thrives in USDA Zones 3-9, adaptable to a wide range of climates.
  • Mature Size: Produces large, white bulbs approximately 3 inches in diameter.
  • Light Requirements: Requires full sun, with at least 6 hours of direct sunlight daily.
  • Soil & Water: Prefers well-draining, fertile soil with a pH between 6.0 and 7.0. Keep the soil consistently moist but not waterlogged.

Planting Instructions:

  • Timing: Plant onion sets in early spring as soon as the soil is workable. In warmer regions, fall planting is also an option.
  • Depth & Spacing: Plant each set about 1 inch deep with the pointed end facing upward. Space sets 4-6 inches apart in rows 12 inches apart to allow ample room for bulb development.

Care Tips:

  • Watering: Maintain consistent moisture, especially during dry periods, to support healthy bulb formation.
  • Fertilizing: Apply a nitrogen-rich fertilizer 2-3 weeks after planting to promote vigorous leaf growth. Cease fertilizing once bulbs begin to form.
  • Weeding: Keep the area around onions free of weeds to reduce competition for nutrients and moisture. Use shallow cultivation to avoid disturbing onion roots.
  • Mulching: Apply a layer of mulch to conserve moisture, suppress weeds, and regulate soil temperature.

Harvesting & Storage:

  • When to Harvest: Onions are ready when the tops turn yellow and start to fall over, typically 90-110 days after planting.
  • Curing: After harvesting, cure onions by laying them out in a dry, well-ventilated area for several days until the outer skins are papery.
  • Storage: Store cured onions in a cool, dry place. Properly stored, they can last for several months.

Additional Tips:

  • Bolting Prevention: Plant at the appropriate time and provide consistent care to minimize the risk of bolting (premature flowering).
  • Companion Planting: Avoid planting onions near beans, asparagus, or sage, as they can inhibit each other's growth. 
  • Pest Management: Monitor for common pests such as onion maggots and thrips. Implement crop rotation and use appropriate organic controls if necessary.

Embark on a rewarding gardening journey with White Snowball Onion Sets and enjoy a bountiful harvest of delicious, homegrown onions!
