Sprinkler Maintenance for Summer: 7 Smart Adjustments to Save Water
Sprinkler maintenance during the peak of summer is the only way to protect your landscape from the scorching sun without draining your bank account. As temperatures climb, most homeowners react by simply increasing their watering time—a move that often leads to massive water waste and shallow, weak root systems. In reality, a few strategic mechanical and schedule adjustments are far more effective than just "throwing more water" at the problem.
At My Dr Sprinkler, we specialize in high-efficiency irrigation. We know that the secret to a resilient summer lawn lies in precision, not volume. By fine-tuning your system for the specific demands of July and August, you can maintain a golf-course-quality yard while using significantly less water. Here are seven smart sprinkler maintenance adjustments you can make today to save water and money.
1. Optimize the "Twilight Hour" Schedule
Watering during the heat of the day can result in up to 30% water loss due to evaporation before the moisture even hits the ground.
-
-
The Adjustment: Set your controller to run between 3:00 AM and 6:00 AM. This allows the water to soak deep into the soil during the coolest, calmest part of the day, ensuring the roots get a full "drink" before the sun starts to bake the surface.
-
2. Implement the "Cycle and Soak" Method
Hard-packed summer soil often can’t absorb water as fast as a sprinkler delivers it, leading to wasteful runoff into the street.
-
The Adjustment: Instead of one 20-minute cycle, program your controller for two 10-minute cycles separated by an hour. This "soak time" allows the first layer of water to soften the soil, making it more receptive to the second half of the watering.
3. Switch to High-Efficiency Rotary Nozzles
Standard spray heads often create a fine mist that easily drifts away in the summer breeze.
-
The Adjustment: Consider upgrading to multi-stream rotary nozzles (like MP Rotators). These nozzles deliver larger water droplets at a slower rate, which dramatically reduces evaporation and ensures a much higher "distribution uniformity" across your lawn.
4. Utilize "Seasonal Adjustment" Percentages
Most modern controllers (especially those found on our home page) feature a "Seasonal Adjust" or "Budget" button.
-
The Adjustment: Instead of reprogramming every zone, use this feature to increase your global watering by 10-20% during a heatwave and quickly scale it back when a rainy week is forecasted. It’s the easiest way to manage your system's output with a single touch.
5. Raise Your Mower Blades
This is a "passive" sprinkler maintenance trick that yields huge results. Taller grass shades the soil, keeping the root zone cooler and reducing the rate of evaporation.
-
The Adjustment: Set your mower to its highest setting (usually 3 to 4 inches). This simple change can reduce your lawn's water requirement by as much as 20% by naturally trapping moisture in the turf canopy.
6. Perform a "Pressure Check"
High water pressure is a silent thief during the summer. If you see a fog-like mist coming from your heads, your pressure is too high, and you are losing water to the wind.
-
The Adjustment: Install pressure-regulated stems or a master pressure regulator. Keeping your system at the manufacturer’s recommended PSI (usually 30-45 PSI) ensures that every drop of water is productive.
7. Inspect and Clean Your Rain Sensor
During the summer, dust and spider webs can clog the sensing discs on your rain sensor, causing it to fail.
-
The Adjustment: Gently clean the sensor and test it by pouring a small amount of water on it while the system is running. A working sensor is your best defense against the embarrassment (and cost) of watering your lawn during a summer thunderstorm. For professional sensor testing, visit our services page.
Frequently Asked Questions (FAQs)
-
Q: How much water does my lawn actually need in the summer?
-
A: Most established lawns require about 1 to 1.5 inches of water per week. During extreme heat, you might increase this by 10-20%, but only if the soil feels dry 3 inches down.
-
-
Q: Is it better to water every day for a short time or once a week for a long time?
-
A: Deep, infrequent watering (2-3 times a week) is always better. It encourages roots to grow deeper into the soil where it stays cooler and wetter.
-
-
Q: Can I use a smart controller to automate these summer adjustments?
-
A: Absolutely. Smart controllers use local weather data to make these 7 adjustments for you automatically, saving you time and guesswork.
-
-
Q: Why is my grass still brown even after I increased the watering time?
-
A: This usually indicates a "coverage issue" or a clogged nozzle rather than a lack of time. Check the spray pattern of the heads near the brown spot first.
