I have a customer who insists on having her lawn cut at 1.5" because she has Bent Grass. According to her this grass can only be cut properly at very low settings due to its horizontal growth. We have accomodated her & her lawn is now burnt as I advised her it would be if we cut at this height. She still insists on having it cut at 1.5" & seems somewhat obsessed with her perception that this is the only way to cut bent grass. I could care less & will continue to kill her lawn if she so wishes, however I am curious if she is correct.
