I am trying to puzzle out the best way to overwinter onions. Based on what I've read, it seems it should be possible to start short-day or intermediate day onion types in the fall, to overwinter and get the bulb development earlier once we reach the 10-12 hour days in early spring, rather than having to wait until later as with the spring started long-day types. I'm not sure if that would actually work. My garden space is limited so I'd like to figure out a way to do onions without them still loitering around in spaces I need for tomatoes and cucumbers. I think I get how the day length works to trigger bulbing - thinking of they had all winter to grow, maybe it would give them enough head start to give me actual onion sized onions earlier in the spring. Thanks! (I'm in SE Portland)
