I go by the rule of getting water on our dormant greens at least once every two weeks in normal winter conditions. If the wind has been blowing, no snow, and warm temps I will water greens weekly. Our temps fluctuate from -20 to +70 during the winter months timing the water is the most important part. Our greens our typically frozen in the morning like yours, and then if the daily temp gets above 50 our top 2 inches usually thaws out. I will usually only water when the air temp is going to stay above freezing until the top surface can dry to try and prevent any ice buildup overnight. It might just make me feel better, but I think the greens always look healthier and refreshed after we water in the winter.
