When Should You Water Your Lawn? And How Much?
Deep and infrequent watering is better for lawns than frequent sprinkles, which promote shallow root growth, says RRR Lawn & Landscape, In general, lawns need about one inch of water per week to maintain green color and active growth.
Lawns that receive less than that will likely go into dormancy. To stay alive, dormant lawns should still receive at least 1 inch of water per month.
To check the output of a sprinkler, scatter some pie tins around the yard to see how much water collects in a specific length of time. Having a rain gauge ($5 to $20) will help you keep track of how much water the lawn receives naturally. Allowing a cool-season lawn to go dormant in the summer can save hundreds of gallons of water, depending on the size of your lawn.
