White Onion Sets will produce large, fine tasting, sweet storage onions with white skins by the end of summer. Over summer the little bulbs will sprout and grow just like regular onions but without the work of starting them early indoors. At the end of the season, once they have sized up to your liking, they get knocked over for drying and later taken inside for curing, just like regular onions. Plant your onion sets in March and April. You may have luck with onion sets as late as May. Keep the growing area carefully weeded and plant in rich, freely draining soil.
Although we do not foresee a jump in prices, spring-harvested live goods are subject to shifts in availability and demand. Please confirm pricing in January.
Choose sweet onion varieties for enjoying raw or cooked within a few weeks after harvest. Storage types keep much longer, and will last until the following spring in the right conditions. All onions are photoperiodic – day length triggers bulb development. Our varieties are all “long day” types, suitable for northern US and Canada.
