I live in Pittsburgh, PA, and plant little onions in the spring. I was wondering if you could plant them in late summer (August), and at least get the small green onion tops until probably December. The problem is that onion sets are sold only until about the end of May, and I have tried to keep them in the basement until August,but with no luck. Could I freeze them or is there something I could put them in so they do not sprout?
Thanks
Tom
