Minutes to Water per Zone Per Month

The chart below is a starting point for the number of minutes to water each sprinkler zone on the days you determine watering is needed. These times are averages. Adjust your watering minutes based on rainfall, type of grass or plants, sunny or shady locations and other characteristics.

Watering two days a week should be sufficient during most of the summer. If needed, water a third day during extreme heat or dry periods. There are no assigned watering days, but never water a zone more than three days a week and never between 10 a.m. and 6 p.m..

Water trees and shrubs as needed, but watering is not allowed between 10 a.m. and 6 p.m.. Shrubs and perennials need half as much water as lawns.
