Ok I would normally leave my flytraps indoors for the winter in a place chilly enough for them to remain dormant. That was when i lived in a zone 5 climate. However the zone hardiness map has been updated and I now live in a Zone 6. I was wondering if my flytraps will be able to survive winter outdoors in this temperature or should I still bring them inside? The carolina's seem to be about a zone 7. it doesn't appear to be that much of a change. Would they survive if I put some clear plastic over it for insulation?
