How to Protect Your Lawn During Extreme Colorado Heat
Colorado summers can be beautiful, but they can also be tough on your lawn. Between high temperatures, intense sunshine, low humidity, and dry conditions, even healthy lawns can quickly become stressed during a heat wave. If you've noticed your grass turning brown, drying out faster than usual, or struggling to recover after mowing, extreme heat may be taking a toll.
At Mile High Grass Cuts, we help homeowners keep their lawns healthy through Colorado's hottest months. Here are some of the best ways to protect your lawn during extreme summer heat.
Why Colorado Heat Is So Hard on Lawns
Unlike many parts of the country, Colorado lawns face several unique challenges:
High elevation
Intense UV exposure
Low humidity
Dry soil conditions
Sudden temperature swings
Limited summer rainfall
These conditions cause moisture to evaporate quickly and can put significant stress on grass roots. Even lawns that receive regular watering can struggle when temperatures stay in the 90s or higher for extended periods.
Raise Your Mowing Height
One of the easiest ways to protect your lawn during hot weather is to avoid cutting it too short.
During summer, taller grass helps:
Shade the soil
Reduce moisture loss
Protect roots from heat stress
Improve drought resistance
Discourage weed growth
For most Colorado lawns, maintaining a height of approximately 3 to 4 inches during summer is ideal. Scalping your lawn may seem like it reduces mowing frequency, but it often leads to more stress and faster browning.
Water Deeply and Consistently
When temperatures rise, watering becomes even more important.
Best watering practices:
Water deeply rather than lightly
Water early in the morning
Avoid midday watering
Adjust irrigation schedules during heat waves
Deep watering encourages roots to grow further into the soil where moisture lasts longer. Shallow daily watering often creates weaker root systems that struggle during extreme heat.
Check Your Irrigation System
Many brown spots are caused by irrigation issues rather than a lack of water.
Inspect your system for:
Broken sprinkler heads
Uneven coverage
Dry spots
Leaks
Overspray onto sidewalks or driveways
A quick irrigation inspection can prevent a lot of summer lawn problems.
Watch for Signs of Heat Stress
Even healthy lawns can become stressed during prolonged hot weather.
Common signs of heat stress:
Brown or yellow patches
Bluish-gray grass color
Footprints remaining visible
Slow growth
Dry or brittle grass blades
Catching heat stress early allows you to make adjustments before permanent damage occurs.
Limit Lawn Stress During Heat Waves
Your lawn is already working hard to survive extreme temperatures.
Try to avoid:
Heavy foot traffic
Excessive mowing
Lawn renovations
Aggressive fertilizer applications during peak heat
Reducing stress gives your grass a better chance to stay healthy through the hottest parts of summer.
Consider a Moisture Manager Treatment
One of the most effective ways to help your lawn handle Colorado's dry conditions is with a Moisture Manager treatment. Moisture Manager is designed to help soil capture and retain moisture more effectively. It can even pull humidity from the air, helping keep your lawn hydrated between watering cycles and rainfall.
This treatment has been shown to reduce water usage by up to 50% while still helping maintain a healthy, green lawn.
Benefits of Moisture Manager:
Better drought resistance
Greener color with less watering
Improved seed germination
Stronger root growth
Safe for lawns, plants, and garden beds
Flexible Treatment Options, we offer:
Single applications
Three-application programs
Monthly treatment programs throughout the growing season
Many homeowners choose recurring applications during summer to help their lawn stay healthier and more resilient during periods of extreme heat.
Don't Ignore Bare or Damaged Areas
Heat-stressed lawns are more vulnerable to:
Weed growth
Soil erosion
Further drying
Disease pressure
Addressing damaged areas early can prevent larger problems later in the season. If your lawn has thin or struggling sections, proper watering, aeration, overseeding, and moisture management can help improve recovery.
Final Thoughts
Colorado's summer heat can be hard on even the healthiest lawns, but a few simple adjustments can make a significant difference.
