We just moved into a new home and had the sod laid this past week. However, it is still winter and the weather is fluctuating between freezing temperatures and nicer Spring like temperatures. I have read that new sod should be kept moist for at least a month but does it make sense to water sod when the temperatures will be hitting freezing in the next couple days? Specifically, it will be in the high 50's this weekend but might snow on Monday. How should I go about caring for this sod? Any help is appreciated.
