As fall temperatures drop, it’s time to start thinking about cold weather prep for your yard and irrigation system. Winterizing your outdoor water systems not only prevents costly damage but also helps you conserve Colorado’s most precious resource. Here are a few important steps to keep your yard waterwise all winter long.

Winterize Your Hose Bibs

While you’re scheduling your sprinkler blowout, don’t forget about your hose bibs (also called outdoor spigots). Taking time to winterize them now can prevent a damaging burst pipe later. The best time is before the first frost and definitely before nighttime temperatures dip below 30 degrees.

If you have a hose bib drip line system, you can use either the gravity method or an air compressor to winterize. Watch this helpful video to learn more.

Protect Your Rain Sensor

If you have a rain sensor connected to your sprinkler system, bring it indoors during the winter. This protects the sensor from freezing temperatures and extends its life so it’s ready to help conserve water next season.

Tree Care Tips

Your trees still need care in the colder months. With a few simple steps, you can help them stay healthy year-round:

• Mulch: Add 2–4 inches of mulch around the base of your trees, but keep it away from directly touching the trunk. Mulch helps soil retain moisture and offers protection from extreme cold.
• Water: Even in winter, Colorado’s trees need water during dry spells. Plan to water every 3–4 weeks on days when the temperature is above 40 degrees. Use about 10 gallons of water for every 1 inch of trunk diameter. Learn more here.

By taking a little time now, you’ll protect your pipes, sensors, and trees from cold weather damage. You’ll also set up your yard for a healthier, waterwise spring.
