killing frost

Crop-destroying cold snap

A killing frost is a frost severe enough to end the growing season by destroying most vegetation.

It's harder than a light frost, which may only damage tender plants.

Gardeners and farmers track the average dates of the last killing frost in spring and the first in fall to plan planting and harvest: We got the tomatoes in just before the killing frost.
