Let me try this again with a pic. This is the first time I've tried this so I hope it works. I live in Buffalo, NY and generally have a beautiful lawn at least up into late summer. Then this grass starts to grow in. For the most part it is green but can turn to light brown when it's dry. It starts to grow in large patches all over. After winter hits and in the spring, it is all dead and I have to rake it out like thatch. I have almost no weeds in my lawn and fertilize in spring, summer and fall. Any ideas of what type of grass this is and maybe a way to combat it. Many thanks.
