The formation of thin ice crystals on the ground or other surfaces Frost develops when the temperature of the exposed surface falls below 32° F and water vapor is deposited as a solid

It is important for gardeners in cooler climates to be familiar with the dates of first and last frost in their area Because many plants evolved in tropical or sub-tropical climates, they are not tolerant of cold temperatures, and permanent damage is caused when the water held in plant cells freezes and expands, severing cell walls Protect against frost by using row covers, cold frames, or other devices that trap warm air around plants Remember also that cold clear nights are more dangerous than cold humid nights because water condensing from cold air can give off enough heat to moderate damage of plant tissue
The covering of ice crystals that forms by direct sublimation on exposed surfaces whose temperature is below freezing
Deposits of white ice crystals or frozen dew drops on objects on or near the ground Formed when the surface temperature falls below freezing (0°)
The covering of ice that is formed on exposed surfaces whose temperature falls below freezing
A deposit of minute ice crystals formed when water vapor condenses at a temperature below freezing
