Grass has dead patches, turning slightly yellow
Hi guys - I was wondering if someone can please help me with my lawn. Its a new lawn. The sod was planted last summer (I think it's Kentucky Blue). It seemed to do ok, not great, but ok. I had very little crabgrass. The heat did take it's toll, but overall, it held up ok.
I put down some Winterguard in the fall. Over the winter, the grass maintained it's green. In the spring, it started blossoming. It looked amazing. I was so happy it was finally coming along.
But now, I'm starting to get these dead patches around the lawn, and it looks a little yellow underneath the green. I have no idea whats going on. Do you guys have any ideas? Please help and TIA.
