Spearmint and peppermint are winter hardy and will most likely survive outside on the balcony with some protection. The chocolate mint is more tender and may not make it. Put the pots close together in a cardboard box or some other bigger container. Add straw under and around the pots and cover the pots with straw. You can also add a blanket over the top of the box.
