10 Summer Lawn Care Mistakes Colorado Homeowners Make
Summer can be one of the toughest times of year for Colorado lawns. Between high temperatures, intense sunshine, low humidity, and occasional drought conditions, grass can quickly become stressed if it's not properly maintained.
The problem is that many homeowners unknowingly make lawn care mistakes that actually make summer lawn problems worse. What seems helpful in the moment can lead to brown patches, weed growth, shallow roots, and increased water usage later in the season. At Mile High Grass Cuts, we see the same lawn care mistakes every summer. Fortunately, most of them are easy to avoid.
Here are some of the most common summer lawn care mistakes Colorado homeowners make and how to prevent them.
Mistake #1: Cutting Grass Too Short
Many homeowners assume shorter grass means less mowing. Unfortunately, cutting grass too short is one of the fastest ways to stress a lawn during summer.
Why it's a problem:
Soil dries out faster
Roots become weaker
Grass becomes more vulnerable to heat
Weeds gain a competitive advantage
Brown patches develop more easily
What to do instead:
Keep your grass approximately 3–4 inches tall during summer. Taller grass helps shade the soil, retain moisture, and protect roots from extreme temperatures.
Mistake #2: Watering Too Often
When temperatures rise, many homeowners respond by watering every day. While that may seem helpful, frequent shallow watering often creates weak root systems.
Why it's a problem:
Encourages shallow roots
Makes grass more dependent on irrigation
Increases disease risk
Wastes water
What to do instead:
Water deeply and less frequently. Deep watering encourages roots to grow deeper into the soil where moisture lasts longer.
Mistake #3: Watering at the Wrong Time
Timing matters just as much as the amount of water.
Common mistakes:
Watering during the afternoon heat
Watering late at night
Why it matters:
Afternoon watering loses significant moisture to evaporation. Nighttime watering can leave grass wet for extended periods, increasing the risk of fungus and disease.
Best practice:
Water between 4 AM and 9 AM whenever possible.
Mistake #4: Ignoring Irrigation Problems
Many homeowners assume brown spots automatically mean the lawn needs more water. In reality, irrigation issues are often the culprit.
Check for:
Broken sprinkler heads
Uneven spray patterns
Dry spots
Leaks
Overspray onto sidewalks and driveways
A simple irrigation adjustment can often solve lawn problems before they become severe.
Mistake #5: Waiting Too Long to Control Weeds
Weeds thrive during summer, especially in stressed lawns.
Common Colorado lawn weeds:
Dandelion
Crabgrass
Thistle
Field Bindweed
Many homeowners wait until weeds have spread throughout the lawn before addressing them.
What works best:
Early intervention. Healthy, thick grass is one of the best forms of weed prevention.
Mistake #6: Over-Fertilizing During Heat Waves
Fertilizer can be beneficial, but timing matters. Applying too much fertilizer during extreme heat can place additional stress on the lawn.
Potential problems:
Fertilizer burn
Increased water demand
Excessive top growth
Additional stress during drought conditions
Always follow product recommendations and avoid heavy fertilizer applications during the hottest periods of summer.
Mistake #7: Ignoring Soil Health
Many lawn problems start below the surface.
Colorado's clay-heavy soil can become compacted over time, limiting the movement of:
air
water
nutrients
Signs of compaction:
Pooling water
Thin grass
Hard soil
Poor drought tolerance
Regular aeration helps relieve compaction and improve overall lawn health.
Mistake #8: Not Protecting the Lawn During Extreme Heat
Even healthy lawns can struggle during prolonged periods of high temperatures. Many homeowners continue normal lawn care routines during heat waves when the lawn is already stressed.
During extreme heat:
Raise mowing height
Reduce lawn traffic
Monitor irrigation closely
Avoid unnecessary lawn treatments
Giving your lawn a little extra protection during heat waves can help prevent long-term damage.
Mistake #9: Not Using Moisture Management Treatments
One of the biggest challenges in Colorado is retaining moisture in the soil. Many homeowners focus only on watering more when the real solution may be helping the soil hold moisture more effectively. At Mile High Grass Cuts, we offer Moisture Manager treatments that help soil capture and retain moisture while improving overall drought resistance.
Benefits include:
Better drought tolerance
Greener lawns with less watering
Improved seed germination
Stronger root growth
Reduced water usage
We offer:
Single applications
Three-application programs
Monthly treatment programs throughout the growing season
For many Colorado homeowners, Moisture Manager helps lawns stay healthier during the hottest months of the year.
Mistake #10: Thinking Brown Grass Is Always Dead
One of the biggest misconceptions in lawn care is assuming brown grass is dead.
In many cases, Colorado lawns simply enter dormancy during periods of heat and drought.
Dormant grass:
Turns tan or brown
Conserves resources
Often recovers when conditions improve
Dead grass:
Pulls out easily
Remains brittle after watering
Shows no signs of recovery
Understanding the difference can prevent unnecessary watering and costly lawn repairs.
