Yellow ‘Stuttgarter’ Onions are easy to grow and one of the most popular vegetables in the home garden! They perform best in well-drained, slightly acidic, fertile soil in full sun. Plant in early spring in well-drained, well-cultivated soil. They may be planted so the sets are nearly touching, and then harvesting every other one for green table onions when tops reach 6” tall. Dry bulbs will be ready for harvest in August or September.
