2 days
per week
Based on the weather for the past two weeks and the forecast for the next two weeks, we recommend watering 2 days per week for the next 14 days.  

This recommendation is only applicable to the watering schedule you received from your Slow the Flow sprinkler inspection. If you no longer have the watering schedule from your inspection, please call 303-999-3824 or email  water@resourcecentral.org   and we will resend your schedule.
It's time to start thinking about shutting down your sprinkler system...

This may be hard to believe considering we're still seeing temperatures in the near 90s across the front range! Despite a summery September, it's important to remember that historic frost date falls on October 15th - about two weeks from now! Follow these tips to keep your lawn healthy for what's left of fall, and start preparing for the fast-approaching end to sprinkler season.
Fall Watering

Especially with the continuing warm day-time temperatures, it's important to keep watering your lawn as needed until the first frost. With minimal precipitation in the two week forecast, we recommend you continue to water 2 days per week, and 0.5 inches per watering day. Overnight temperatures have started to cool off, providing your cool-season grasses with their preferred growing conditions. Adequate supplemental watering will allow your grass to take up necessary nutrients during this growth period, but as always, don't overdo it! Overwatering can weaken your lawn's root system, and make it more susceptible to fungal diseases.

The most important step in winterizing your system is to blow it out. Or, put simply, its important to clear the pipes of all water once you turn off your control clock and switch off the valve on your backflow preventer.

Blowing out your sprinkler system is one of the most crucial elements of the long-term maintenance of your sprinklers and should not be taken lightly. If water sits in the pipes when the temperatures go below freezing, the water will freeze and potentially break the underground pipes.

If you are unlucky enough to have pipes break over the winter, you wouldn't know it until the start of the next irrigation season. At that time, you would have to have sprinkler contractors come out and fix the pipes for you, a very costly endeavor.

So to avoid any possibility of breaking a pipe, we highly recommend getting your system blown out by a sprinkler professional. This is a particularly busy time for contractors that offer this service, so consider contacting a trusted contractor soon and getting on the schedule no later than October 15th.

Or if you are confident in your DIY skills and have access to an air compressor, there are plenty of online instructions on how to blow out your system, such as this fact sheet from CSU Extension, or  this video from Ewing Irrigation . But when in doubt, don't hesitate to contact your local sprinkler company to do it for you.
The Colorado Sprinkler Guide is here to help you avoid overwatering! By providing you with weather-based watering recommendations, our goal is to keep you on track with your sprinkler schedule and prevent overreactions to hot temperatures that lead to drastic and unnecessary increases in watering times.

Why do leaves change color in fall?
Leaves change color as daylight decreases. Shorter days in autumn trigger a mechanism in the tree to close up veins in leaves, cutting off the supply of chlorophyll, the substance that gives plants their green color. The chemicals that produce orange, yellow, and red foliage are always present in leaves, but they're masked by green pigment most of the year, and make an appearance only when chlorophyll production has stopped in fall!
