Lawn fungus is a common issue faced by homeowners and landscapers in Central Florida. Fungi are microscopic organisms that thrive in warm, humid conditions, making Florida particularly susceptible to fungal infections in lawns. These fungi can cause a range of problems, including aesthetic damage and health concerns for your grass.

How to Identify Lawn Fungus 

Keep an eye out for patches of grass that are discolored and have slow growth. Here’s what you need to know about some of the most common types of Central Florida lawn fungus:  

• Brown Patch Fungus: Brown Patch Fungus is one of the most prevalent lawn diseases in Central Florida. It typically appears as circular, brownish patches ranging from a few inches to several feet in diameter. Brown patch fungus in your lawn can quickly dominate the entire lawn unless you promptly implement effective lawn care measures.
• Dollar Spot: Dollar Spot creates small, round patches resembling silver dollars. These spots can merge to form larger affected areas. This fungus can spread when you step on it and then walk to another area of your lawn. 
• Gray Leaf Spot: Gray Leaf Spot manifests as small, brownish-gray spots with yellow halos on grass blades. The blades of grass will wither and die if the leaf spots are numerous. 
• Fairy Ring Fungus: Fairy Ring Fungus forms rings of dark green or dead grass and is often accompanied by mushrooms or toadstools in the center. It can reduce the amount of water that the soil absorbs, causing the grass in the ring to brown and die. 
• Take-All Root Rot: This fungus primarily affects the roots of St. Augustine grass, leading to thinning and yellowing of the grass. It can affect the overall density of the root system, causing weak, brown, dead patches. 

Lawn Care Tips to Prevent Fungus

Proper lawn care is essential to preventing lawn fungus from taking over your property. Here are some effective lawn care tips: 

• Reducing Heavy Thatch: When thatch accumulation is excessive, it creates an ideal breeding ground for lawn fungus. To combat this, consider core aeration, which enhances water penetration in your soil while promoting better air circulation. 
• Fertilizing: Nitrogen fertilizer can significantly impact your lawn’s health and appearance. For expert guidance on the right type and amount of fertilizer your lawn needs, consult a lawn care specialist. 
• Proper Watering: Water is vital for your lawn, but overwatering dry soil can be detrimental. The onset of lawn fungus is more likely when water accumulates on grass blades without penetrating the soil, allowing fungi to thrive. 
• Professional Fungicide: Even seemingly healthy lawns can foster lawn fungus. Early detection and swift fungicide treatment can have a substantial impact. However, always consult a lawn care professional before applying any treatment.
