If you cut your lawn to ultra short levels and put fuckloads of pesticides on it, then chances are you arent actually USING your lawn anyways. If you actually use your lawn you know its way nicer to have a little wild growth with flowers and shit going on.
Maybe thats regional but in my experience living in a couple german cities, “textbook lawn” equals “unused lawn” that purely exist as wealth symbol. Not saying it cant be well kept but there are variying degrees of that.
