How Much Water Does Your Yard Really Need?

Baffled by trying to match landscaping sprinkler schedules to the changing seasons? Is some part of your yard shaded, and some parts in full sun? Is your soil mostly clay, or fast draining sand? Many property owners go for a single setting and stick to it, often keeping their lawn too wet and wasting water. Understanding where, when, and how much water we use is the first step in beginning to conserve one of our most precious resources. Using this online calculator will allows you to customize your outdoor irrigation schedule based on soil conditions, plant type, and sprinkler type. If you have multiple zones to calculate watering times for, use this Zone Worksheet to keep track.

This is a simplified schedule based on averages for the Spokane regional area. Small adjustments made over time to your watering schedule will help increase the efficiency of these recommendations. Remember, apply only the water that your landscaping needs will help keep your plants healthy, and it will help all of us use this important resource wisely
