Florida’s warm, wet environment creates the perfect conditions for fungal infections, particularly during spring and fall. Fungal problems are often hard to notice until they’ve already spread, which is why it’s important to familiarize yourself with the common lawn fungi in Florida. Some of the most frequent offenders are:
Brown Patch Fungus
This fungus flourishes in warm, humid environments, causing brown or yellow patches to appear on the lawn. These patches often have a circular or irregular shape with a dark border. The grass along the edges may look water-soaked and show lesions.
Powdery Mildew Fungus
Known for its white, powdery growth on grass blades, this fungus gives the lawn a grayish appearance, particularly in the early morning. It thrives in cooler, wetter conditions, which is why it’s more frequent during the winter months.
Fairy Ring Fungus
The fairy ring fungus, despite its whimsical name, usually appears in lawns that are overwatered. It forms distinct circles of dark green or dying grass, often bordered by mushrooms. These growths are most frequent during the warm summer season.
Dollar Spot Fungus
Lawns with poor drainage or excessive watering, particularly during warmer months, are prone to this fungal problem. It’s characterized by small, tan, circular spots roughly the size of a silver dollar. The affected grass may show tiny reddish-brown lesions on the blades.

Methods for Preventing Lawn Fungus
Fungal infections can seriously harm your lawn, and once they appear, they can be tough to eliminate. Fortunately, with proper care, you can minimize the chances of your lawn developing fungus. Here are some of the best prevention methods:
- Avoiding Overwatering Your Lawn: Overwatering promotes a moist environment perfect for fungi to thrive. Water your lawn deeply but infrequently to maintain a healthy balance.
- Fixing Any Drainage Issues: Poor drainage causes water to pool, leading to fungal growth. Ensure proper drainage to prevent excess moisture from accumulating on your lawn.
- Applying Fertilizer Twice Per Year: Fertilizing your lawn twice a year strengthens grass and helps it resist fungal infections. Apply in spring and fall for the best results.
- Mowing Regularly: Mowing keeps grass healthy and reduces the moisture where fungi can thrive. Maintain a consistent mowing schedule and avoid cutting the grass too short.
- Routinely Aerating the Soil: Aeration allows air, water, and nutrients to penetrate the soil, helping to prevent fungal growth. To ensure your lawn stays healthy, aerate it annually.
- Removing Thatch Buildup: Thatch buildup creates a damp environment that fosters fungi. Remove excessive thatch to improve air circulation and reduce the risk of fungal infections.
- Getting Expert Lawn Care: Professional lawn care experts can identify early signs of fungal infections and apply the right treatments. Regular care from a specialist ensures long-term lawn health and fungal prevention.
What to Do If You Have Lawn Fungus
Treating fungus is challenging, and lawn infections are no different. If you detect any signs of disease in your grass, taking swift action is essential to avoid widespread damage.
To ensure accurate diagnosis and treatment, it’s a good idea to consult a local lawn care professional. They can help identify the specific fungus and uncover any underlying issues affecting your lawn’s health, offering tailored solutions. Their expertise can also save you time and money by preventing the need for costly treatments that might not address the root cause.
