Fruit and Vegetable Frost Protection
"Freeze protection efforts should be based on the type of freeze, temperature, and wind speed that is impacting your crop. To apply frost protection, consider your crop value, the freeze protection capacity of your system, and the crop’s susceptibility to injury at each growth stage.
Types of Freezes A freeze refers to the temperature at which water freezes, 32 degrees Fahrenheit (32 °F) or 0 degrees Celsius (0 °C). A frost occurs at temperatures where water condenses as ice, which directly relates to the amount of water vapor in the air. Because frost can form at varying temperatures, it is important to consider the type of freeze that is affecting your crop and when the temperature will reach the freezing point of water.
Advection Freezes are typically associated with the movement of a weather front into an area. Cold and dry air replaces the warmer air..."
