Onion Sets

Onion sets are flavorful, nutritious, and one of the most popular vegetables in the home garden. They're easy to grow and thrive in full sun with well-drained, slightly acidic, fertile soil. Start by planting the sets close together, nearly touching. As the tops reach about 6 inches tall, you can harvest every other plant for fresh green onions. The remaining onions will mature into dry bulbs, ready to harvest when their tops naturally dry out and fall over in late summer. Gently lift the bulbs with a fork and store them in a cool, dry place for long-lasting use.
