Hello, I am sorry if I posted this in the wrong part of the forum. Last October I did my first sod job. Everything came out beautiful. Late this March we did a Spring clean up on the same property. The sod I installed looked good, nice and green. I just noticed the other day that it started to look yellow, as you see in the pictures. Even some of the existing grass has patches like this, but I am getting concerned. I have spoke to a few of my friends and they said it would be fine and they gave me some reasons of why its happening. They said things like, it was dry for a month, or after the snow melted it probably went dormant, it was not winterized last Fall. But I just wanted to get some the expert opinions on this site and also what steps should I take to get it back to where it should be. Thank you.
