I live in a a dry, hot desert climate. Most everyone in our area wants their lawns mowed short (11/4-2" . The lawns suffer and I am frustrated. People won't listen . The first good heat wave just hit and it is getting ugly here . Is there a good way to keep a short lawn green ? Every lawn is a kentucky-rye-fescue blend. It seems that all otherservices are mowing short .
