Hello grass experts I am just a new home owner who was looking on the internet for answers to a problem I am having with my lawn when I discovered this forum. I am hoping you can help me out. I have some spots in my lawn that get bare of grass and what appears to me to be moss takes hold. However, I question if this is moss because it's only in the parts of my lawn that get the most sun and seems to get worse as the summer goes on and the weather gets warmer and sunnier. From the little I know (think I know) about moss it's in shady damp areas. Below are some pictures, starting looking from far out to where you can just see the grass appears to be thinning, to a closer shot of a bare spot up close. Also, how do I treat whatever this is and get my grass back to normal? Thanks! Edit: I live in upstate NY if that tells you anything.
