Superstar Onion Plants

Superstar Onion Features:

Our Superstar Onion Plants produce large, globe-shaped white onions with incredible flavor. This variety is an All-American Selections winner and performs best in the middle of the country in the intermediate day onion growing region. It can also be grown by gardeners in the northern portion of the short day onion growing range and gardeners in the southern portion of the long day onion growing range.

These Superstar Onion Plants produce strong, vigorous tops that protect the white bulbs from sun discoloration as they mature. These onions are great when sliced raw or used for adding wonderful flavors to your favorite dishes. Superstar onions have a storage potential of approximately two months after harvesting.

Superstar Onion Growing Tips:

Our Superstar 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!
