Water applied to a lawn during the hottest part of the day tends to evaporate before it has time to soak into the roots of the grass. Adjust lawn watering to the weather. Following a heavy rain, skip your regular watering day until the grass needs it. Know how to turn off your automatic sprinkler system until it is needed again. Water flow can be controlled at the water outlet by the type of sprinkler used and by the size of the garden hose.
More water is dispensed faster with larger diameter hose.
Oscillating sprinklers are very inefficient. Sprinklers throwing large drops of water in flat patterns are more effective than those with fine, high sprays. When watering near sidewalks, driveways, and patios, push a root feeder or water aerator into the soil 12 to 16 inches from the concrete. Force the water jets down to a depth of four to six inches. When the grass raises up like a bubble, remove the spike and repeat the operation 12 inches farther along the grass edge.
