protection

Yesterday evening when I saw the temperature was eighteen degrees below freezing, and felt the icy draft near each window I remembered that houseplants need to be kept from the cold, too. This is something I've done in years past- either pull plants off the windowsill for the night (here my Jades that habitually sit behind the desk)

or put a layer of cardboard between the plants and the glass. If the days turn sunny, I'll pull the cardboard, then put it back at night. Keeps the worst of the chill off the plants.
