What, impacts and precautionsHide details
What
Temperatures of 33 to 36 degrees will result in frost formation.
Impacts
Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered.
Precautionary actions
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.
