What are the most common lawn fungi in the Southeastern US?

The Southeast is home to several aggressive fungal diseases. The most common fungal diseases we treat across our service areas include: Brown Patch — the most widespread fungus in the Southeast, thriving in the hot, humid summers of Georgia, the Carolinas, and Tennessee, primarily affecting cool-season grasses like Tall Fescue but capable of impacting warm-season grasses too. Large Patch (Zoysia/St. Augustine Patch) — a warm-season fungus that spreads aggressively in Zoysia and St. Augustine lawns, typically flaring up in fall and spring when soil temperatures shift. Dollar Spot and Leaf Spot — common across all five of our states, targeting a wide range of turf types and spreading quickly in wet, humid conditions.

What time of year is lawn fungus most prevalent?

Fungus season in the Southeast depends on your grass type. Brown Patch thrives in the hot, humid summers of June through September. Large Patch and Zoysia Patch, on the other hand, tend to flare up in fall and spring when soil temperatures shift. In our service areas, that means vigilance is needed for much of the year, which is why our program runs on a consistent treatment schedule throughout fungus season.

How do I know if I have a lawn fungus?

Lawn fungi typically appear as irregular brown or tan patches, often in circular or ring-shaped patterns. You may also notice discoloration before the grass fully dies — yellowing, orange or reddish tinting, or a grayish-white film (mycelium) visible in the early morning before the dew burns off. Fungi tend to show up first in the dampest areas of your lawn, such as low spots or shaded sections that stay wet longer. If you're unsure, give us a call — our technicians are trained to identify specific fungal diseases on sight.

How quickly can a fungus take over my lawn?

Many fungi are very quick moving and can eat through an entire lawn in just a few days. That's why it's best to have treatments in place during fungus season before the disease has a chance to spread.

How does a lawn fungus make its way into my lawn?

Warm, damp environments are perfect conditions for fungi growth. Fungus often enters your lawn naturally from wind or rain, and can be quickly spread by lawn mowers.

Will the grass grow back in after the fungus is killed?

Unfortunately, any grass that a fungus overtakes is dead and will not come back without reseeding or sodding. This is why early treatment and prevention are so important — stopping the spread before more turf is lost.

What steps can I take on my own to help prevent lawn fungus?

A few things that help prevent lawn fungus: proper watering (not too much, not too little); mowing on a regular basis at the proper height; cleaning any tools used on the lawn to prevent spreading fungus to other areas; and removing any debris from your lawn, as it is prime breeding ground for many fungi.

Preventive Fungicide

Some lawns are susceptible to fungus issues, so applying fungicides after the appearance of the disease and continuing the application will help prevent the spread of fungus on your lawn.

Applications include treatments for the specific fungus that is already present in your lawn. Each fungus treatment is tailored to the type of disease and turf type. We treat the entire turf.

You can expect a professional, friendly technician who knows what he's doing. Our fungicide technicians are trained to know what each fungus looks like and how to treat the disease.

Healthy Lawn Promise

Our technicians do the job right, and we have a 100% satisfaction guarantee. Please contact us if you have any questions or concerns about your lawn fungus treatment.

Preventive Treatment Saves Grass

Keep in mind that although targeted fungicides will kill the fungus that is currently active in your lawn, they will not bring back grass that has already died due to fungus. Applying fungicides is essential to the reduction of the spread of the disease throughout the lawn and less turf loss.
