    3.5 - 4" is all you need. Higher than that and most machine start leaving stragglers badly. I cut at 3.5- 4" all season long.

    3.5-4, shorter than 2.75 is crazy, above 4, unless your machine is great with tall heights your cut quality may suffer. Right on the money. I'll only cut shorter than 3 if it's a weekly customer that insists on it, and I will not skip after that cuz their lawn is dormant. Too bad.

    To the original poster, I once did some deep thinking on this subject at once time, and it took me a while to figure it out. Your referring to "University Studies" telling you to cut a particular grass at a particular height. For example, many University Studies say to cut St. Augustine at 3" for example. I cut St. Augustine at a minimum 4" - 4.5". Why and what I learned from these stories? Go back and read the study. How much water does it say to put down per week? It all boils down to temperature, water, and so on before you get a good HOC. You can't get a correct HOC without knowing these factors. In the article you read, it may say cut at 3", but it may also say water 1" per week. With that said, I have customers that want their St. Augustine cut at 3", yet they have an isolating sprinkler on a hose in their lawn. The go to work in the day, come home turn the sprinkler on, and claim their lawn is "irrigated." Do they know their water pressure output? Do they know how much water that isolating sprinklers putting out? It can take an isolating sprinkler 3 up to even 6 hours to put out a full inch of water over a 2,000-4,000 square foot area. Are they running their sprinklers for five hours or the appropriate amount of time after work to get one full inch of water from that particular sprinkler? Most likely not, why would you cut at a HOC at 2.75" if it recommends at least 1" per water per week via University Research, yet it's not getting one full inch of water? Make sense? Irrigated lawns are much easier to cut at such heights, but when I say "irrigated" that's a diverse word. Most customers are using big-box sprinklers and don't now what their putting out, and A LOT of people even have irrigation systems and still don't know how much their putting out. You can read study after study, but we all know in a drought and heat, cut high and it does better especially when not given adequate water, especially when we're on drought restrictions. With that said, I have St. Augustines that I'm now cutting at 4.5" to 5" over this past month due to the extreme drought. One of my best looking St. Augustine lawns is cut at 4.5" every week.

    One rule I live by now days, if you're going to cut it like a golf coarse, YOU MUST, water it like a golf coarse. Which you (my customer) don't do, thus, I can't cut it like a golf coarse.
