While beau- tiful to see, the very mention of frost sends gardeners in both fall and spring scurrying for protective covering to keep plants safe from the cold.
Just what is frost, and what does it do?
There are two types of frost, advective and radiation.
Advective frost occurs when a cold front sweeps into an area, with typically gusty winds. It is rare for the first frost of the season.
The first frost typically is a radiation frost, which also is known as hoar frost. These occur under a clear sky and calm winds.
