Is watering your grass when freezing bad?

Watering your grass when freezing is not recommended as it can cause damage to your lawn. The cold temperatures can cause ice crystals to form on the blades of grass, which can then break and damage the grass. Additionally, the freezing temperatures can also damage the roots of the grass, making it more susceptible to disease and pests. Watering your grass in the early morning when temperatures are still cool is a better option, as the water will not freeze on the grass and will have time to soak into the soil before the sun rises and temperatures rise.
