City of Petaluma Irrigation Schedules


It’s not uncommon for home gardeners to accidentally overwater their lawns, leading to water being lost through gutter flooding (run-off) and water going past the root zone. For the irrigation season, we recommend watering your lawn in three 4-minute applications, separated by at least one hour each cycle (a total of 12 minutes). The only factor that will change monthly is the number of days per week you water.

If the weather is unseasonably cool, hot, or wet, adjust the irrigation schedule. Equally important, know your soil moisture! Poke a screwdriver into the soil in several places. In areas that are moist, it will penetrate easily. In areas were the soil is dry, it will be harder to penetrate the soil. In evaluating your lawn needs, water when your soil is dry down to 2"-3".
