How to Treat & Identify Florida Lawn Fungus
That brown patch on your lawn that keeps getting bigger? It might not be from insects or drought—it could be a fungal infection. In Florida’s hot, humid climate, lawn fungus is a common problem that spreads fast and damages turf before many homeowners even know it's there.
At AssureGreen, we specialize in identifying and treating lawn fungus before it takes over. Here's what you need to know.
Common Lawn Fungi in Florida Lawns
Florida lawns are especially susceptible to fungal diseases, particularly in the warm, wet months. Some of the most common culprits include:
1. Brown Patch (Rhizoctonia)
- Large circular patches of brown or yellowing grass
- Often starts small but can spread rapidly
- Most common in the cooler months on warm-season grasses
2. Dollar Spot
- Small, sunken patches about the size of a silver dollar
- Can merge into larger areas if left untreated
- Appears during periods of high humidity and low nitrogen
3. Gray Leaf Spot
- Gray or tan lesions on grass blades, often with a darker border
- Especially affects St. Augustinegrass
- Thrives in rainy, warm conditions
How to Prevent Lawn Fungus
While Florida’s climate makes fungus hard to avoid, good lawn care practices can reduce your risk:
- Water Early in the Morning: Allows grass to dry before nightfall, reducing moisture buildup.
- Avoid Overwatering: Fungal diseases thrive in consistently damp soil. Adjust irrigation based on rainfall and season.
- Keep Mower Blades Sharp: Clean, sharp cuts help grass recover quickly and resist infection.
- Aerate Compacted Soil: Reduces thatch buildup and improves drainage—two key steps in preventing fungal growth.
