In making plans for my first attempt at vermicomposting here in Zone 5A, I am wondering whether and to what extent this activity may continue uninterrupted, albeit slowly, during the winter months. Do the red worms die off in winter or just hibernate if left outdoors in their box in a dormant garden? If they are likely to die/freeze out, would it be sufficient to move the plywood worm box into an unheated garage or uninsulated outdoor storage building instead? Or do you folks build insulated worm boxes for such environments even for the unheated, uninsulated shed? The web sites I've seen so far do not seem to address these particular questions directly.
Thanks,
J.
