Frosts and Freezes

What's the difference between a frost and a hard freeze? A frost refers to the conditions that allow a layer of ice crystals to form when water vapor condenses and freezes without first becoming dew. A hard freeze is a period of at least four consecutive hours of air temperatures that are below 25 degrees F. Many plants can survive a brief frost, but very few can survive a hard freeze.

TIP: The chill of a moderate frost or light snow improves the flavor of brussels sprouts, cabbage, carrots, kale, leeks, parsnips, and turnips.
