After 7 years of letting my lawn be "good enough" I decided this year I really wanted to upgrade at least one area to "really nice". One of the biggest issues I have here (Pacific Northwest) is moss, most people say there's not much you can do about it, but when you look at the "really nice" lawns in the area they are moss free. I aerated and corrected the pH to hopefully discourage new moss growth. My approach to ridding the lawn of the existing moss was to mow, dethatch, spray the moss, dethatch again to pull up the dead moss, top dress and overseed, and then continue on with fertilizing and mowing on my regular schedule. I am currently at the "dethatch again" portion of this routine and after 4 passes with the power rake I'm still pulling up dead moss and thatch. This is about 4,000 sq ft of grass and I've already filled my 96 gallon yard waste container twice and about a dozen of those 30 gallon paper compost bags too. I've attached pics below of the raked up piles I'm getting from each pass with the dethatcher and a close up of the remaining thatch/dead moss that's still in the grass. I'm starting to feel like this is a fools errand... should I keep going till I can see bare ground between the grass or am I going to start damaging the lawn? Should I break this up into monthly/quarterly applications to allow it to recover? Should I just bite the bullet and buy a Harley rake and rip the whole lawn out and reseed? If I were to overseed now would that even work or would the seed just sit on top of the moss/thatch and go to waste? Thanks for any advice you can provide!
