Max water "...Water long enough to moisten the soil down to about 6 inches, which is the average depth of a healthy grass-root system..." --If you just bought a new sprinkler, calculate its flow rate to determine precisely how much water is being sprayed onto the lawn. Multiply the square footage of your lawn by 0.62 gallons; that’s the amount needed to reach one inch of water per square foot. Then, divide by your sprinkler’s flow rate to determine how long to water.
watering clay soils once a week (twice a week max)
Minimum water "If homeowners don’t want to water their lawn, that’s fine,” Maurer says. The lawn will go dormant just as it does in the winter, which won’t harm the grass as long as there’s not a drought lasting longer than a month. However, if you let the lawn go dormant, you can’t suddenly start watering, and then discontinue watering, and then water again. That’s too hard on the grass.
Determine what inputs are needed to decide whether or not to turn the sprinkler system on.
