We recently moved into a 10 yr old house with about 2 acres of lawn (almost all sun all day). It was December so I was not totally concerned that it was brown. It started out great in the spring but it has struggled in spots this summer. It seems that the area that the water runs toward (the Back yard) is producing more weeds and less grass. This area was very moist and spongey for most of the wet spring. I have decided to try to straighten it out this fall, and prepare for next year. I am thinking of De-thatch or airate and seed/furtilize, with a sunny seed. Any thoughts? I am really playing this by ear since I have very limited experience. I welcome any and all ideas. Thanks!
