What is frost forming on grass?

Frost forming on grass occurs when the temperature drops below the dew point, causing moisture in the air to condense and freeze on the grass blades. This process typically happens during the night or early morning when temperatures are colder and humidity is high. The result is a thin layer of ice that appears as white crystals on the grass, often creating a picturesque winter scene. Frost can indicate that the air temperature is low enough to potentially harm sensitive plants.
