What height to mow grass to conserve water ?

A tenth of an inch an hour sound impossible. Honest. KState is 50 miles from me and call for an inch in an hour about once a week if under 100 F. Over that they call for twice a week but seldom do it. My grass is on a pretty good slope and never runs off until a good 2 inches is put on. My Bermuda out back is flat and can take a hard 2 inch rain in a heartbeat. One tenth of an inch per hour in summer would evaporate here in the heat of summer. It would take ten hours to put on an inch and at least one half of that at 100 to 105 temps. We mow at the highest or second to the highest setting and water cool season grass once a week with an inch of water unless we have rain.

Well it looks like maybe you have not checked out the precipitation rates on sprinklers in a while because in order to put down an inch of water you need to run the biggest nozzle Hunter has which is a 12 for one hour and sixteen minutes at 50 psi. A typical spray zone runs about 25 minutes and you will put down about .20 inches about an average of three to four times a week. There are resources you can look at to find out exactly what you are putting down instead of guessing.
