Have you ever considered watering your lawn? If you install a sprinkler system all you have to do is program it and it does all the work.
I know I can water it, but I do not like wasting water on grass. I water my garden, it produces a valuable food source, I don’t eat grass. So it looks bad, I am not so pretty myself,IMO water is too valuabale a resource to squander on grass, especially during a drought.
