Frost does not fall from the sky, but is directly condensed by water vapor in the near-surface air, which is a solid form of water.

There is a lot of water vapor in the atmosphere or a large temperature difference between day and night. There is no wind at night, and there are attachments on the surface to facilitate the condensation of water vapor.
