Long Day Onion Plant Collection

Our Long Day Onion Plant Collection includes a bundle each (50-70 plants) of three different long-day onion varieties that perform great in the middle of the country. 

Long Day Onion Plant Collection Varieties:

Walla Walla Onion Plants

Our Walla Walla Onion Plants produce colossal sweet onions that have a slightly flattened shape. This is a fast-maturing variety that will be ready to harvest before the other varieties in this collection. Walla Walla was developed in Washington State and is very cold hardy.

Redwing Onion Plants

Our Redwing Onion Plants produce globe-shaped, red onions with long storage potential. These slightly pungent onions are great when sliced raw or cooked. They are bolt resistant and will usually store for 8 months after harvesting.

White Sweet Spanish Onion Plants

Our White Sweet Spanish Onion Plants produce jumbo onions that are great for making homemade onion rings. These globe-shaped onions have a high sulfur content and a strong onion flavor, making them great for cooking. They average 5" in diameter and usually store for 4-6 months after harvesting.

Long Day Onion Plant Collection Growing Tips:

Our Long Day Onion Plant Collection 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!
