July is when North Texas lawns face their biggest challenge. As rainfall tapers off and temperatures climb, grass has to work much harder to stay healthy. This is also when we start seeing the same questions come into the store: Why is my lawn turning brown? Is it bugs? Am I watering enough?
The good news is that a few simple adjustments now can help your lawn handle the rest of the summer.
Water Smarter, Not More
One of the most common mistakes we see this time of year is watering too often for short periods.
Shallow watering creates shallow roots, and shallow roots struggle when temperatures reach the upper 90s and beyond. Instead, water deeply so moisture reaches the entire root zone.
A good goal is to water until the soil reaches field moisture capacity—the point where the soil has absorbed all the water it can hold before excess begins to run off. If runoff starts, stop the cycle, let the water soak in, then run another cycle if needed. This cycle-and-soak approach helps water penetrate deeper instead of running down the street.
Whenever possible, water early in the morning. It reduces evaporation and allows the lawn to dry as the sun comes up.
Is It Chinch Bugs or Drought?
If you have St. Augustine grass, don’t assume every brown patch needs more water.
Chinch bugs are one of the most common summer lawn pests in North Texas. They usually show up first in the hottest parts of the yard—next to sidewalks, driveways, curbs, and other paved surfaces.
If watering isn’t improving those areas, take a closer look before increasing your irrigation. Treating chinch bugs early with Bifenthrin can prevent them from spreading to the rest of your lawn.
Keep an Eye Out for Gray Leaf Spot
Warm, humid weather creates ideal conditions for gray leaf spot, especially in St. Augustine lawns.
The disease often appears as tan or gray lesions surrounded by a darker border. Left untreated, those small spots can quickly spread and thin out otherwise healthy turf.
If you notice the early signs, applying a fungicide like F-Stop right away can help stop the disease before it causes widespread damage.
A Healthy Lawn Doesn’t Happen by Accident
Beautiful lawns aren’t created with a single fertilizer application or one extra watering. They’re the result of paying attention to what your lawn is telling you.
A few minutes spent checking your irrigation, watching for insects, and catching disease early can save you a lot of time—and money—later in the summer.
Johnson Feed Pro Tip
If your lawn suddenly starts turning brown in July, don’t automatically reach for the sprinkler. Brown grass isn’t always thirsty. Before adding more water, check for signs of chinch bugs or gray leaf spot. Identifying the real problem first is the fastest path to a healthy lawn.
