If you did have frost on the turf last night you most likely will not see the results of it until last night. Generally it is the frost settling that does the damage I believe and not so much just the cold temps. Also wind burn/damage is common and from when I was out last night I do not doubt we will see a bit of it as well as it was windy as heck.Is it the below freezing temps or frost that cause damage(browing) to the grass? I had below freezing temps last night but no frost. Thanks
This is exactly what most home owners should do since they cannot run all of their irrigation zones at once..
When I had a nursery standard protocol was to run the sprinklers during the day to saturate the ground. Then turn them off at dark and try and cover as much as possible. The water helped hold the ground heat and stop minor frost and freeze. Citrus people do it different as do many others, but this worked for me.
