Frost Dates for Rockbridge Area

Frost dates are the day of the year when it is calculated to be 50% likely that the temperature will dip below freezing, resulting in frost on the ground.

When temperatures drop to a range of 29-30 degrees Fahrenheit, a ‘light freeze’ will damage delicate plants. A ‘moderate freeze’ will damage most plants in your garden except the hardiest, and it occurs with temperatures between 25-28 degrees Fahrenheit. A ‘severe freeze’ is almost always fatal to all garden plants, and it occurs when temperatures are lower than 24 degrees Fahrenheit.
