Lawn Fungus & Disease FAQ – Get the Answers You Need
At Mid-South Turf Professionals, we know that dealing with lawn fungus and disease can be frustrating and confusing for homeowners. To help you understand the causes, treatments, and prevention methods, we’ve compiled answers to some of the most frequently asked questions. Our goal is to provide you with expert insights and practical solutions so you can restore and maintain a healthy, disease-free lawn year-round.
Signs of lawn fungus include brown, yellow, or dead patches, circular or irregular spots, white or gray powdery coatings, red or pink threads, or thin, weak grass. If your lawn isn’t responding to regular care, it may be suffering from a fungal infection.
Fungal diseases thrive under certain conditions, including:
- Excess moisture from overwatering or poor drainage
- High humidity and warm temperatures
- Compact soil that restricts airflow and water absorption
- Nutrient imbalances, such as low nitrogen levels
- Mowing too short, which stresses the grass
In some cases, minor fungal issues may clear up with improved lawn care, such as proper watering and fertilization. However, severe fungal infections will continue to spread unless treated with fungicides.
The most common lawn diseases we see in Oakland, Germantown, Collierville, and surrounding areas include:
- Brown Patch – Large, circular brown patches in warm-season and cool-season grasses
- Dollar Spot – Small, round yellow patches about the size of a silver dollar
- Powdery Mildew – White or gray powdery coating on grass blades
- Red Thread – Reddish-pink threads visible in affected areas
At Mid-South Turf Professionals, we apply targeted fungicide treatments to stop the spread of disease and help your lawn recover. We also recommend aeration, proper fertilization, and adjusting watering schedules to improve lawn health and resistance.
Fungicides stop the spread of the disease, but the damaged grass needs time to recover. We also address the underlying causes of the fungus to prevent it from returning.
Yes, our fungicide treatments are safe when applied correctly. However, we recommend keeping children and pets off the lawn for 24 hours after treatment to allow the product to dry and fully absorb.
It’s best to avoid mowing for 24-48 hours before and after treatment to allow the fungicide to properly absorb and take effect.
