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.
Consider 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.
