Watering Tips

Throughout much of the year, lawns in Western Oregon receive adequate moisture from rainfall. During the summer months it is necessary to supplement the rainfall with irrigation. Lawns which do not receive adequate moisture will turn brown and become dormant. The purpose of this page is to alert you to the signs of drought stress and to give you some tips on how to water most effectively.


How Often to Water

Watering your lawn deeply and infrequently (2-3 times a week) will promote a deep rooted lawn which is able to withstand stresses. Shallow, daily watering will result in a weakly rooted lawn, which is prone to invasion by insects, diseases and weeds. The ideal watering frequency depends on the weather and you soil and grass types. In general you should not need to water each part of your lawn more than three times per week if you are watering deeply.


How Much to Water

Lawns in Western Oregon require from one to two inches of water per week during the summer. There are several different types of sprinklers available for different situations. Each of these sprinklers applies different amounts of water per unit of time. This makes it difficult to give a general length of time to water your lawn. There is a test you can use to determine the amount of water your sprinklers are applying. This test is called the “Pie Pan” test. The Pie Pan test involves placing pie pans or other wide, shallow containers around your lawn and watering for an hour. At the end of the hour measure the water in the pans. Then determine how long you need to water to fill the pans to a depth of on half inch. If you apply one half inch of water to each part of the lawn three times per week your lawn will look its best all summer.


How to Find Out if Your Lawn is Getting Enough Water

Footprints will remain visible longer in a drought stressed lawn. If footprints are still visible after two minutes your lawn is in need of more water.

On a lawn which is receiving adequate irrigation you can easily insert a screwdriver to a depth of six inches. In a dry lawn it will be difficult to insert the screwdriver.

A dry lawn will appear pale green to brown and will crunch when you walk on it.



If the water runs off your lawn rather than penetrating the soil you need to have it aerated. We would be happy to provide this service for you. A soaker hose left on for several hours will allow the water to penetrate better on sloped or compacted areas.

For water conservation it is best to water your lawn during the early morning or late evening when the evaporation is at its least. However you will not burn your lawn by watering at midday.

If you do not water your lawn regularly and it becomes dormant, it will be very difficult to revive. It will take about three weeks of regular watering before the lawns dormancy can be reversed.
