Watering prior to spring freezes/frosts?

Asked June 6, 2019, 11:56 AM EDT

I have heard that one should water prior to a freeze/frost to help prevent the plant from freezing as it would keep the soil a bit warmer, is it true?

Hi, Wet soil does hold heat longer than dry soil which can help protect roots, but the best way to protect your plants from cold injury or frost damage is to cover them with frost cloth or a sheet or an upside down nursery pot at least at night then it can be removed during the day as the weather heats up. If you do decide to water the soil I would do it by mid afternoon and not too late into evening for nights where it is going to get below freezing.

Thanks
