As it happened, "reasonable height" was defined by town ordinance to be 12" or less. With sufficient rain, towards the end of summer, the grass could grow 2-3" per day. I never tried to stop other plants from growing. The grass kept itself a monoculture through sheer density. I have never seen its like since I moved away.
