Lawn Fungus in Georgia: Identification, Causes, & Treatment
A healthy, green lawn can quickly become an eyesore when **fungal diseases** take hold. Many Georgia homeowners struggle with **brown spots, thinning grass, and discolored patches** caused by **lawn fungus**. These diseases thrive in warm, humid conditions and are often triggered by **excess moisture, poor drainage, compacted soil, or improper lawn care**. Identifying lawn fungus early and applying the right treatment can prevent **permanent damage and costly lawn repairs**. Below, we’ll go over the **most common lawn fungi found in Bermuda, Zoysia, and Fescue lawns**, how to **identify their symptoms**, and the best ways to **treat and prevent them**.
If you’re seeing fungus and mold in your yard, it’s evidence of a deeper problem, literally.
Fungi and spores are naturally present in Georgia soil, and can manifest visually when there are conditions such as moisture imbalance, temperature extremes, poor air circulation, or an imbalance of vital nutrients.
Along with recommended weed control and fertilization practices, a professional lawncare service like Absolute Green Landscaping can apply a fungicide treatment to the yard to suppress the fungus that is dormant in the soil of your yard.
