Im in Kalamazoo. It is nice to have but takes up a lot of real estate in a two car garage.
I was at 4" a couple of weeks ago. Then took it down .5" at a time to 2.5" over a period of about a week. It looked like garbage! Bad time of the year to do such a thing. There were a lot of clippings and brown tips even with sharp mower blades. Ended up having to bag it because there were so many clippings but at least it looked a little better.
Next few times I let it grow back out to 3" which is where I cut it today.
Looks good in the shade (camera/photo lighting)
No crab grass this year. I did two apps of dithiopyr/fertilizer on April 15 and May 15. Last year I didnt do preemergent and got hammered with crabgrass. But this photo is from Aug 25 so I guess the worst is yet to come.
Interesting comparison two photos from last year - June 11, 2018 before crabgrass and Aug 25, 2018 after crabgrass
I also aerated last year on June 14 which didnt help combined with no preemergent. I purchased a ride-on Classen Standaer and I wanted to badly to try it out even though timing was wrong. I sold it at the end of last year and now I am using a Ryan LawnAire 28.
I am also in the process of digging out around the sprinkler heads, and raising them up a little bit as well as replacing a few. I installed them below grade so they wouldn't get run over but I think this allowed dirt and debris to get in and ruin the gears. So I am going to try and keep the surrounding areas cleared out so it doesn't happen again.
Now giving the lawn a bit of water .1" and enjoying a Founders Centennial IPA while watching the sprinklers do their thing. Looks like approx. 2 week period with no rain. I watered a lot 2017 and got bad fungus. Last year 2018, I watered lightly each morning, enough to remove the guttation water in the morning and no big fungus issues. This year I am trying an approach of just giving it enough to keep from going dormant during dry periods.
Oh and here is my mower with homemade striping kit that I built a couple weeks ago.
