The Walla Walla Sweet Onion maturity date is 100 to 125 days, depending on size. These are a fair keeper! This variety is the standard that almost all sweet onions are measured to, and will produce loads of uniformed, softball-sized onions that are firm, big, and sweet. And the Walla Walla sweet is a long day or a day neutral onion. We carry from pack sizes to bulk Heirloom seed. For the best selection, buy our Heirloom, Non-GMO, onion seeds online.
Basic growing tips: Keep your seedbeds moist. This is one of the most important parts of the germination process. They take ten to fourteen days to germination. You will want to space around four inches apart and farther apart for bigger bulbs.
These are great onions for fresh, farmers market sales. Happy growing!!!
