I currently live in North Carolina and this past fall I had tall fescue sod and an irrigation system put in my backyard. This spring I used Scotts fertilizer (in March). Since then I have been watering my lawn twice a week for 25 minutes each session (unless it was already raining).
I was cutting my lawn once every couple of weeks for the past couple of months. In the last two weeks I have started doing it once a week (I learned that you do not want to cut more than 1/3 of the blade with each mow). I use a bagged lawn mower and take the grass clippings away from my yard.
A couple of weeks back I noticed that my fescue was starting to wilt (see attached pictures). I have tried doing some research online but the only information I can find points to Brown Spot disease. Looking at my grass it does not appear to match the description of brown spot disease though.
Why is my fescue wilting and what can I do to make it green again (and stay green)? I am considering consulting with TruGreen but figured I would seek advice online first.
