White Sweet Spanish Onion Features:
Our White Sweet Spanish Onion Plants produce jumbo onions that are perfect for onion rings, salads, soups, and more! This is a long day onion variety that performs exceptionally well in the northern states. It can also be grown on the northern edge of the intermediate day onion growing region.
White Sweet Spanish Onions are globe-shaped and have a high sulfur content that gives them their signature, pungent onion flavor. These may be harvested early for small cooking onions or left in the ground to reach their full potential. White Sweet Spanish Onions average 5" in diameter at full maturity and will usually store 4-6 months after harvest.
White Sweet Spanish Onion Growing Tips:
Our Yellow Sweet Spanish Onion Plants should be planted in late winter, approximately four to six weeks before your average last frost date. Established onion plants can tolerate temperatures down to 20°F, but young onion transplants will be more sensitive. Place the onion transplants 6" apart in your raised bed or in-ground garden and water them well for best results.
Onion plants are heavy feeders and will perform best in fertile soils. If your soils are not naturally fertile, you'll need to fertilize the plants to grow large onions. Feed the onions a balanced fertilizer (relatively equal parts of N-P-K) at planting or shortly after. Once the plants establish and start growing, feed them a couple times with a nitrogen-based fertilizer and watch them grow!

Farm Fresh Onion Plants
Our onion plants are field grown to ensure the highest-quality onion plants for our customers.
After being harvested from the field, our onion plants are cleaned, trimmed, boxed, and shipped to you. We want our customers to have the freshest plants so they can be successful growing their own onions.
When your onion plants arrive, open the box immediately and unwrap the individual onion plant bundles. We recommend planting them as soon as possible, but they'll be fine in a cool dry area for one to two weeks.
