Hi DTC, Bays are semi hardy,they can put up with the bad weather until it gets really bad and then they need a little help. I have two in large pots that are still in a sheltered spot in the garden. Usually, the real bad weather kicks in around the end of January to February, I then bring them into an outhouse to shelter from the wind and heavy frost. I bought them three and a half years ago and they seem happy with this arangement. I've not repotted them yet but I agree with Rustylady, spring is a good time
