@JungleShadows would have the best advice for winter your babies in Upstate New York.
I leave mine outside in the beds year round. My tiny ones made it through last winter at 5°F with no snow cover. Then it warmed up and rained, then it got cold again and rained. They all made it. But I would hate to give advise and have you lose your wonderful babies. You have several that look promising, and itsy bitsy to the front left of center is really interesting.
