We’ve been out in neighborhoods all over—Nichols Hills, Tuttle, Choctaw—servicing lawns that are fighting to survive the heat. One of the biggest differences between a thriving lawn and one that’s struggling in July? A properly working sprinkler system.
Every year around this time, we visit properties where sprinklers are watering sidewalks, timers are running in the middle of the day, or valves are stuck open and flooding beds. At the same time, we see lawns with healthy green turf, even in 100° weather, simply because their irrigation is dialed in. It’s not luck. It’s planning.
If your lawn is dry, patchy, or under stress this summer, now is the time to take a closer look at your sprinkler setup.
Why July Is So Challenging for Lawns in Oklahoma
By July, the Oklahoma heat is relentless. We often go two or three weeks without meaningful rain, and temperatures regularly hit triple digits. Your lawn, plants, and soil are all under stress.
The challenge isn’t just the heat—it’s how fast the soil dries out. Oklahoma’s heavy clay soil holds water for a bit, then dries out fast and cracks. If your irrigation isn’t keeping up or running at the wrong time, your grass has little chance of staying healthy.
Common Sprinkler Issues We See Every July
Here are the problems we fix most often for clients across the metro:
1. Clogged or stuck sprinkler heads
Heads that don’t pop up all the way or spray unevenly can lead to dry spots that appear for no obvious reason.
2. Mismatched coverage
Different nozzles in the same zone or poor spacing creates inconsistent watering. Some areas get drenched, others barely see a drop.
3. Faulty valves
When valves fail, zones can stay on too long or not turn on at all. We’ve seen water bills double because of unnoticed leaks.
4. Poor watering schedules
Running your system during the heat of the day? That’s when most of the water evaporates. Running it at night? That increases the chance of fungus and turf disease.
When Should You Water?
The best time to water your lawn in Oklahoma is early morning, between 4:00 a.m. and 8:00 a.m.
This gives the soil time to absorb the water before the heat sets in. Avoid watering in the afternoon—it’s inefficient—and avoid watering late at night, when moisture lingers and encourages disease.
How Long Should You Run Your Sprinklers?
It depends on the type of heads you’re using:
- Spray heads (typically in small areas): 10–15 minutes per zone
- Rotary heads (larger, rotating heads): 20–30 minutes per zone
Bonus tip: For clay-heavy soil, consider cycle and soak watering—run each zone for 5–10 minutes, then wait 30 minutes and run again. This reduces runoff and helps water soak in deeper.
How to Tell if Your Lawn Isn’t Getting Enough Water
Here are the most common signs of lawn heat stress:
- The lawn looks dull, with a bluish or gray tint
- Grass blades fold or wilt
- Footprints remain after walking across the grass
- Brown or yellow patches, especially in sunny areas
If your sprinkler system is running regularly but you're still seeing these signs, there may be issues with coverage or run time.
Do Water Restrictions Apply?
Oklahoma City and many nearby communities implement odd-even watering schedules in summer. If your address ends in an odd number, you water on odd-numbered days. Even-numbered homes water on even-numbered days.
It’s important to follow these guidelines. You can find full details here:
City of OKC Watering Rules
We recommend updating your sprinkler timer to stay compliant while still providing enough water early in the morning.
Don’t Forget About Trees and Garden Beds
Turf isn’t the only part of your landscape that suffers in July. Shrubs, flowers, and young trees need consistent moisture too.
If you’re watering these areas with overhead sprinklers, you're likely losing water to evaporation. Drip irrigation is a better option—it waters directly at the base of plants with minimal waste.
We also recommend adding 2–3 inches of hardwood mulch in flower beds and around trees. Mulch helps keep the soil cooler and reduces how quickly it dries out.
Should You Upgrade Your Sprinkler System?
If your sprinkler system is more than 10–15 years old, or if you’re constantly adjusting it manually, it might be time to upgrade.
We recently worked with a client in Blanchard who was hand-watering his entire yard twice a day. We installed a smart sprinkler system with Wi-Fi scheduling and rain sensors. Within two weeks, his lawn looked significantly healthier—and he cut his water usage by nearly 40%.
Modern systems save time and money while keeping your landscape in better condition.
