Rare are the meals we prepare without onion! Fruition’s organic onion seeds are heirlooms are well-adapted for short seasons, long-storing over the winter and delectable in all seasons. Here in Zone 5, we sow onions indoors in open trays in early spring, often early March, transplanting in early May, several weeks before final frost. Enjoy young onions anytime & harvest full-size onions once their tops become soft and fall over, curing well to enjoy them for months to come.
