Water better with the weather

The amount of water needed by plants changes with the weather and length of day. Regularly adjusting the watering schedule is essential to maintaining a healthy landscape.

It’s easy!

Start with a good watering schedule. Create your own irrigation schedule and program your sprinkler controller using the calculators from the resource list of the Garden Washington website.

Once you’ve made a schedule and entered it into your sprinkler timer, adjust it every week or two to match the weather. Learn how to use the features on your timer to water efficiently.
