Frost damage occurs below 0°C.

Is it true that frost damage occurs below 0°C?

Partly. Several sources tie frost damage to temperatures at or below 0°C, but each covers only a narrow setting such as conifer needles, brick walls, or building materials. One Canadian crop dataset instead places the damaging frost temperature at -2°C for cool-season crops, so the evidence covers part of the claim and partly conflicts with it.
