Daily Lawn Watering Guide

The daily Lawn Watering Guide is designed to help you determine the right amount of water for your lawn. The guide lists how many minutes of watering your lawn needs and is posted from May to October.


The forecast is expecting light rain today and tomorrow, with high temperatures rising to 74°F on Sunday.

Lawn watering accounts for nearly half of the water used annually by most homes, and up to 70 percent of water demand on a summer day. Lawns typically get more water than needed. Too much water can be just as damaging as too little.

A lawn loses water through evapotranspiration (ET) and is replenished through rainfall and sprinkling. The ET rate tells how many inches of water a typical lawn uses through surface evaporation and plant transpiration. ET is calculated based on temperature, humidity, wind and sunshine. Watering guide amounts are based on the ET rate for bluegrass, minus any effective rainfall.


What about my sprinklers?

To find out how much water your sprinklers apply to the lawn, sign up for a free sprinkler system audit. You can also measure sprinkler output for each zone or station with three steps:

  1. Randomly place six soup cans of equal size within the spray of the sprinklers.
  2. Turn on the sprinkler for 10 minutes.
  3. Pour all the water from the cans into one can. Measure the depth of the water. The result is the "inches per hour" that your sprinklers are delivering to that zone.

To find how many minutes it will take to deliver half an inch of water, divide half an inch by "inches per hour" and multiply by 60. For example, if a zone delivers 2 inches per hour, it would take 15 minutes to apply half an inch.
