<bot>: The best way to keep your plants from getting too cold in the winter is to provide them with adequate shelter. Place them in a sunny window, or near an exterior wall that gets direct sunlight during the day. Make sure to water them regularly and provide them with fertilizer and other nutrients as needed. Additionally, if you are able, move the plants outside for a few hours each day so they can get some fresh air.
