A healthy, green lawn is a source of pride for many homeowners—but even the most well-maintained lawns can fall victim to disease. Fungal infections, environmental stress, and poor drainage can all trigger lawn issues that turn your lush yard into a patchy, discolored mess. At Purposed Landscaping, we’re here to help homeowners in The Woodlands and surrounding areas recognize the early signs of lawn disease and apply effective treatments to bring their yards back to life.

Common Types of Lawn Disease & How to Spot Them

1. Brown Patch
Brown Patch is one of the most common fungal lawn diseases in Texas. It typically appears in the warm months and is caused by excess moisture and humidity. You’ll notice large, circular patches of dead or brown grass, often with a darker border.

What to do:
Improve drainage, avoid overwatering, and mow with a sharp blade. A fungicide treatment may be necessary in severe cases.

2. Dollar Spot
This disease is named for the silver-dollar-sized spots it creates on your lawn. It thrives in low-nitrogen soil and humid conditions.

What to do:
Fertilize your lawn properly and water early in the day to allow the grass to dry out. Fungicide can help eliminate the disease if needed.

3. Rust
If your lawn looks orange or yellow and leaves a powdery residue on your shoes, you’re likely dealing with rust fungus. It weakens the grass and makes it more vulnerable to other stressors.

What to do:
Mow and bag the affected grass clippings. Aerate the soil and ensure your lawn is getting enough nitrogen.

4. Fairy Ring
Fairy Ring appears as dark green or brown rings in your lawn, sometimes with mushrooms along the edges. This disease is caused by soil-dwelling fungi and is notoriously tough to treat.

What to do:
Deep aeration and consistent watering can help reduce symptoms. In some cases, removing the affected turf and soil is the best option.

5. Leaf Spot
This disease starts with small purple or brown spots on grass blades, eventually causing the entire blade to die. It often appears in spring and fall.

What to do:
Avoid watering in the evening, and keep your mower blades sharp. Treat with a fungicide if it spreads.
