When to Turn off Sprinklers in Colorado

Colorado is known for its beautiful landscapes and diverse climate, but it also faces unique challenges when it comes to water conservation. With limited water resources and an arid climate, it is essential for residents to be mindful of their water usage, especially when it comes to outdoor irrigation. Knowing when to turn off sprinklers in Colorado can help conserve water, save money, and promote a healthy environment. In this article, we will explore the best practices for watering your lawn and gardens in Colorado, as well as answer frequently asked questions related to sprinkler usage.

Understanding the Climate

Colorado experiences a semi-arid to arid climate, with low annual precipitation and high evaporation rates. This means that water is a precious resource that needs to be conserved, especially during dry seasons. Colorado’s climate is also characterized by distinct seasonal variations, with hot and dry summers, and cold winters.

Best Time to Water

To maximize water efficiency and promote healthy plant growth, it is recommended to water your lawn and gardens during the early morning or late evening. This is because temperatures are cooler and there is typically less wind, reducing evaporation rates. Watering during midday can result in significant water loss due to evaporation. Additionally, watering during the cooler parts of the day allows plants to absorb the water before the heat of the day sets in.

Watering Guidelines

When watering your lawn, aim for deep and infrequent watering rather than shallow and frequent irrigation. Deep watering encourages the development of deep root systems, making plants more resilient to drought conditions. It is generally advised to apply around one inch of water per week for lawns and gardens. However, this may vary depending on factors such as soil type, plant species, and weather conditions.

Monitoring Soil Moisture

Before deciding to turn off your sprinklers, it is essential to monitor the moisture levels of your soil. This can be done by inserting a soil moisture meter or simply by digging a small hole and feeling the soil’s moisture content. If the soil is consistently moist to a depth of six inches, it may be a sign that your sprinklers can be turned off temporarily.

Factors to Consider

While there are general guidelines for when to turn off sprinklers in Colorado, it is important to consider additional factors that may influence your watering schedule. These factors include:

1. Seasonal variations: Colorado experiences different weather patterns throughout the year, with wetter springs and falls, and drier summers. Adjusting your watering schedule accordingly can help conserve water.

2. Rainfall: If your area receives significant rainfall, you may be able to reduce or turn off your sprinklers temporarily. However, it is crucial to ensure that the rainwater has adequately penetrated the soil before making any adjustments.

3. Plant type: Different plants have varying water requirements. Native and drought-tolerant plants generally require less water compared to non-native species. Understanding the water needs of your plants can help optimize your watering practices.


Q: Are there any watering restrictions in Colorado?
A: Watering restrictions may vary depending on local regulations and water district requirements. It is recommended to check with your local water provider to determine any specific restrictions in your area.

Q: Can I water my lawn during drought conditions?

A: Along with following recommended watering guidelines, you can conserve water by practicing proper lawn maintenance techniques such as mowing at the correct height, aerating, and using organic fertilizers. These practices promote water retention and reduce the need for excessive watering.

Q: Should I turn off my sprinklers during winter?
A: Yes, it is generally advised to turn off and drain your sprinkler system before winter to prevent freezing and damage. This can be done by shutting off the main water supply and draining any remaining water from the system.

In conclusion, knowing when to turn off sprinklers in Colorado is crucial for water conservation and responsible water usage. By following the recommended guidelines, monitoring soil moisture, and considering various factors, residents can ensure the health of their landscapes while conserving water resources.
