Outdoor potted plants should now be placed in a protected location.

Plants that survive fairly cold weather when planted in the ground will often be injured when exposed to the same temperatures in containers or pots. Potted roots often die when temperatures drop below 18-20°F. You can protect container roots by piling sand or sawdust around them or placing them in a protected place next to the house. Row covers can also be used to protect potted plants. Do not forget to periodically water the plants that are under the eaves of the house.
