Last spring, I had some sprouting onion starts not yet in the ground. I tucked them in among the small tomatoes and forgot about them as the tomatoes took over. During the tomato row clean up this fall, I displaces some of the onion bulbs and just thought I'd try again another year.
Now I see onions sprouting throughout the garden (I forgot some of the places I stashed them)! I'll see how they do over the winter rather than my too late planting in the spring. They don't seem mind the frosty nights at all.
