My garden just gave up and died during our summer heat wave and drought (except for the crabgrass - I have a record crop of that). Since the onions never reached eating size before they shriveled, I just assumed they were dead and ignored them.
Well, when I finally got around to weeding a week or so ago - with the weed whacker - I noticed an oniony smell. Sure enough, my onions had send up nice baby onion plants! Since I need to till and plant cereal rye, I dug the baby onions up and planted them in the big raised bed, along with garlic, spinach, carrots, beets and dinosaur kale. I'm not sure I'll be able to eat any of these things over the winter, but it should give me a head start on the early spring garden.
