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.
Evaluate your soil type. The type of soil under your lawn, as well as the climate and time of year, will dictate how often you need to water your lawn. If you live in an area that is prone to heavy rainfall during parts of the year, for example, you will not need to water as frequently.
