Cold hardiness for red wigglers -
It would be good to know. I read where the wigglers tend to stay near the surface of the soil unlike natives. Maybe they'd last the season in spots where I have a good layer of leaf mulch. I wonder if the escapees would miss their bananas? I don't fret about a few escaping but I want enough to keep up with winter-time scraps when the worms are slowing down.
