My house is on the right its a camper. I'm just kidding I can't afford a camper in this neighborhood. I can afford to mow their MTV cribs though. This is 4" s and blue grass its gets gypsum 3x's a year uria once a month wet app, iron every 6 weeks wet app slow release nitrogen 4x's a year and selective herbicide wet app 2x's a year. Moral of the story is you're only cutting to tall if it looks bad and cutting to short is always worse then cutting to tall.
The heck there is not, you cut your grass too tall and it looks like crap, lays over, and will increase the risk of the grass dying under it so don't tell me there is no such thing.
