I don't know about your areas but most of my lawns have had serious frost damage.(St.Augustine and Zoyia lawns) The ones that had the most trees still have green grass but the rest of the lawns are brown. This is my second week and the lawns didnt need to be cut. It looks like it will be awhile until I start cutting the St.Augustine again. I think the best thing to do is to stay off of the grass. What are your lawns looking like.? This damaged happened last week when temps got down to the low 30ies at night.
