Answer: Mints as a group are quite cold hardy and the snow will protect the tops, so if you can insulate the pots the plants should be fine. The best way would be to plant them, pot and all and dig them up again in the spring. Another option would be to huddle them together and heap mulch around the pots. Yet another option would be to put them in a cold frame. Finally, when they have gone dormant, set them in an unheated garage until spring. One other thing -- if your pots are terra cotta any freezing weather will probably ruin them. If this is the case, repot into plastic.
