This will be their first winter here. I have a place that stays around freezing for most of the winter but when the temps drop below -20 outside I’m not sure how cold it will get. So, while I do some temp testing over the winter these will live in a fridge in my garage from October to March. I’m still pretty new to actually trying to keep trees alive ver the winter here. It’s going to be tough, but can’t be impossible. Just need to figure a system out.
