Instructions:
Take steps now to protect tender outdoor plants from the cold. Consider temporarily moving outdoor potted plants indoors if they are sensitive to cold temperatures or temporarily covering sensitive plants with a lightweight cotton fabric (i.e., bedsheets, thin blankets), as this will help retain heat and provide frost protection for your plants.
