A green, healthy lawn is something most homeowners take pride in. But once summer arrives, many notice brown patches creeping across the yard. It’s frustrating, especially when you’re putting in the effort to water and mow regularly. The good news is that most brown spots have clear causes—and with the proper care, they can be fixed.
Heat and Drought Stress
One of the main reasons grass turns brown in summer is the heat. When temperatures rise and rainfall is scarce, lawns go through stress. Even regular watering may not be enough because the soil dries out so quickly.
Drought stress often shows up as irregular brown patches where the grass feels thin and brittle. If you step on the lawn and the blades don’t spring back, that’s a sign the roots are thirsty. The best way to help is by watering deeply but less often, so moisture reaches the roots. Early morning watering works best since it gives the grass time to soak up water before the midday sun.
Lawn Diseases
Not all brown patches come from lack of water—sometimes they’re caused by fungal diseases that thrive in warm, humid conditions. Brown patch disease and dollar spot are common culprits. They usually appear as circular or irregular patches that spread if not treated.
Thick, damp lawns create the perfect environment for fungus. Cutting your grass too short or watering in the evening can make the issue worse. To reduce the risk, mow at the proper height for your grass type, clear away thatch, and avoid overwatering. If the problem continues, a fungicide may be necessary.
Insect Damage
Another cause of summer brown spots is insects. Chinch bugs, grubs, and sod webworms can all damage your lawn by feeding on grass roots or blades. The result is dead, patchy areas that don’t bounce back even after watering.
One clue is grass that lifts easily because the roots are gone. You may also notice birds pecking at your yard, looking for grubs. In this case, treatment may include applying an insect control product or introducing beneficial nematodes to target the pests naturally. Learn more about our grub control services.
Poor Soil Conditions
Sometimes the problem isn’t on the surface but below it. Compacted soil and poor drainage can keep water and nutrients from reaching the roots. These areas often dry out faster and show uneven growth.
Aerating once or twice a year creates small holes that let water, air, and nutrients sink deeper. Pairing lawn aeration with overseeding and seasonal fertilization helps build a stronger, healthier lawn.
How to Prevent Brown Patches
Here are a few habits that make a difference:
- Water deeply once or twice a week instead of light daily watering
- Keep mower blades higher to protect the soil and conserve moisture
- Fertilize in spring and fall to prepare the grass for hot weather
- Aerate compacted soil and overseed thin areas regularly
- Watch for early signs of pests or disease before they spread
