maybe I kept mine too warm. In the northeast it is hard to find 40-50 degrees in winter. basements are usually warmer than that because of the heating systems. garages get too cold. attics get cold, but can heat up on sunny days so the temp. is never constant. whats a boy to do? LOL. I am sure my corms are still fine, but those pseudostems looked like dead cornstalks. this spring they aregoing in the ground with the other two.
