Answer: You can store them inside in a cool (~40-45F), dimly lit place for the winter to make sure they have their winter "beauty rest". If you've been feeding your mums, stop now, and gradually reduce watering. When the foliage has faded, cut it back to the soil surface and bring them inside. Check occasionally to make sure the soil doesn't dry out completely. When spring nights remain above freezing, repot, and put them outside. Eventually, you can divide them to increase their numbers. Enjoy!
