Run your sprinkler and see how long it takes to get a half inch of water in the can â just like a rain gauge. Usually itâs about 30 minutes. So 20 minutes, 3 times per week will get an inch of water on your lawn, and 30 minutes 3 times per week will get 1 Â½â down. Bear in mind that during extreme heat, you will need to water more, due to evaporation and heat stress on the grass. Water deeply 2-3 times per week, rather than daily.
Q. How often do I water my lawn and what time of day? A. If you use a sprinkler system, the recommended watering in summer is for the lawn to receive 1 inch of water, 2 to 3 times per week with the water penetrating 8 to 10 inches. Using tuna cans you can determine if 1 inch of water was used and for how long.
