Kirk, I think your lawn looks pretty damn good-pics only tell so much. Everyone has to remember the extreme conditions from last year's drought and heat, brutal for turfgrass in our region, even with irrigation. Seems like a distant memory now, eh? my lawn from this morning after a previous day of mulching beds, so it's had some foot traffic. I have cut mine as well (as all my clients) at 3"(always) for years-with great results. edit to add: cutting every 3-4 days with this spring's perfect storm!
