For properties with irrigation systems:  Begin watering in the Spring around two to three times a week, for roughly 15 minutes per zone for spray heads in smaller areas, and 30 minutes per zone for rotor heads in larger open areas.  Water in the early morning hours concluding before sunrise.  Avoid watering in the evenings, as it can promote fungal infestation.  Established lawns need about 1” to 2” of water per week to thrive.  As the temperatures increase during the summer, you may need to increase to daily watering during high heat or drought.  Consider adding a rain sensor to your system, so the irrigation will only run as needed during times of inclement weather.  Frequently check coverage for isolated dry areas, as heads can be easily bumped and need recalibrated.  Cut down your watering frequency, as temperatures get cooler.    For properties without irrigation:  Every living organism needs water, so no matter how much product is placed on your lawn, it will not thrive without water.  Invest in an irrigation system, or hoses and oscillating sprinklers, to deliver much needed hydration to your lawn.  Oscillating sprinklers come in different coverage ranges, so make sure to know the size of your lawn.  Watering times for oscillating sprinklers increase, as they distribute about an inch of water per hour per zone.  Established lawns need about 1” to 2” of water per week to thrive.  Watering in the early morning is ideal to prevent evaporation.  Avoid watering in the evenings, as it can promote fungal infestation. Cut down your watering frequency as temperatures get cooler.
