DO. . .
• Water in dry weather.
• Water early in the morning.
• Water every 5-6 days in hot weather.
• Use sprinklers that are close to the ground rather than high in the air, because larger drops are better than fine mist.
DON'T. . .
• Water from mid-morning to late afternoon. You will Lose 1/3 of your water to evaporation. Try watering before 10AM.
• Over water because it causes valuable nutrients to wash away.
• Water too frequently because it causes shallow root system to develop.
• Water at night because the grass stays wet and encourages the development of disease.
HOW LONG TO WATER
--Let sprinkler soak an area for about 30 minutes. Dig a spade into the ground and see for yourself whether the water is getting down deep enough; if not water for another 30 minutes.
IF YOU WATERED ENOUGH
--Step on a patch of grass. If the blades spring up, then no watering is necessary. If they don't, then you need to water.
