Don’t forget to provide extra protection to houseplants on window sills if it is very cold. Place cardboard between the plants and the glass. Be sure the plants don't touch the windowpanes.
Also, check any bulbs and tubers you may have stored to determine if moisture is okay. Repack bulbs that seem too damp, discarding any moldy ones. If bulbs seem too dry, try moving them to another location.
