Organic Non-GMO Onion Seed
We offer certified organic onion seed for varieties of sweet onions, yellow storage onions, red onions, shallots and bunching onions, also known as scallions. Onions are cool season biennials that depend on day length for bulb development. Short day onions begin forming bulbs with 11-12 hours of daylight. Long day onions require 14-16 hours and intermediate day onions fall somewhere in between. When seedlings started indoors reach 5 inches in length, trim to increase size before planting.
