Subsurface lawn irrigation in Phoenix
Has anyone tried Subsurface lawn irrigation in Phoenix? I am really tired of pulling grass from outside the boundaries of my lawn due to overwatering. No matter how I set the sprinklers, either it doesn't cover the lawn enough or overwaters. I'm not talking about drip irrigation or flood irrigation, but actually subsurface irrigation.
I heard it's better for the lawn, 75% less water and less mowing. I haven't found any company who installs it or anyone who has it.
