 First of all, you want to make sure that you're watering your lawn early in the day, and that's going to prevent evaporation. If you water at night and then leave that lawn wet, that grass could develop a fungus disease. Also, you want to make sure that you adjust those sprinklers to avoid wasting water by having it directed away from your driveways, your sidewalks. Basically, don't water things that can't grow, guys. Okay? Oh, I see that all the time because the only thing that grows when you water your sidewalk is your water bill, right?
