I put this fescue sod down in my yard 6 weeks ago and it has been doing good just getting some yellow blades in the yard. It is not just one patch here and there it is pretty much spread out through the whole yard. I just put down some 24-2-11 do you think the nitrogen will help the yellow green back up. I attached some pics that you can see what I am talking about. It seems like it has had a little yellow in it from the start but is worse than it was so I hope this helps. Thanks for any suggestions.
