This variety is also commonly called Stuttgarter Riesen, or Giant Stuttgart. Seed Origin: Italy Sowing: February to April Harvesting: August to October How To Grow Stuttgarter Onion From Seed: Prepare shallow drills to sow your onion seed directly into. Leave a spacing of 30cm between the drills. Sow the seeds thinly, and cover lightly with soil. When the seedlings establish to roughly 5cm in height, thin them to leave the strongest plant every 10cm. The thinned seedlings can be grown somewhere else for Spring onions if desired. When the leaves start to die off in late Summer/Autumn, your onions should be harvested for storage. Let the harvested onions dry out in the sun, or another alternative way for a few days before storing them. Stuttgart onion stores very well, they should last until the following Spring in a cool and dry place. Seed count is approximate.
