City of Petaluma Watering Schedule        

Lawn

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.  This sample lawn watering schedule shown below will benefit your landscape and your wallet! As shown by the graph below, water your lawn based on the number of days per specific month. 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 # of days per week you water.

For example for the Month of August:

Water your lawn in four-minute intervals, three times before sunrise for Four days each week.

Watering in shorter periods, instead of a long irrigation, reduces

runoff and allows water to penetrate the soil more deeply!

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”.
