first frost

Growing season's end

First frost is the first occurrence of freezing temperatures in autumn, marking the end of the growing season.

Gardeners watch for it anxiously, harvesting tender crops before cold kills them: We picked the last tomatoes just before the first frost.

The date of first frost varies by region and elevation, appearing in almanacs and planting guides.
