Common Lawn Diseases That Can Ruin The Look of Your Yard

With the weather getting warmer it can only mean one thing; spring is in the air in Georgia. Before you know it, it will be time to get out the lawnmower, pruning shears, and gardening gloves. There’s nothing like a fresh start to a new planting season. There are so many possibilities and the choices you make now will affect your lawn for the rest of the season. But before you start planning your lawn care schedule be sure to be aware of another threat lurking beneath your grass. I’m talking about lawn diseases. brown patch on a lawn

The wet, humid conditions that are a common part of our spring create the ideal environment for lawn diseases to form. If you aren’t careful, lawn diseases can kill large swaths of your beautiful lawn, all but dashing any hopes you had at having a picture-perfect lawn this year.

Brown Patch

Brown patch is one of the most common lawn diseases we see in Georgia lawns. This devastating disease affects all grass types and is caused by excessive wetness. Brown patch will appear as round patches of brown grass that can be anywhere from just a few inches wide to several feet. Brown patch is most common in the spring when hot and humid conditions favor its growth. The disease can weaken and kill your grass and leave it vulnerable for weeds to invade.

Changing when you water can go a long way in preventing brown patch. We recommend watering in the morning to allow your grass time to dry out. If your lawn does not dry out then you may want to consider lawn aeration as an option.

Large Patch

Large patch and brown patch might be indistinguishable to the untrained eye, but this disease only attacks warm-season grasses like zoysiagrass, Bermudagrass, St. Augustinegrass, and centipedegrass. Large patch appears as enormous areas of brown, irregular-shaped areas of grass that can exceed twenty-five feet or more in width. 

As with brown patch, large patch is a disease that thrives in hot and humid conditions. If you can mitigate these conditions then you have a shot at beating large patch to the punch.

Fairy Ringlawn damage

When you were a kid you might have thought fairy rings were the stuff of myth and fantasy. It’s fun to imagine that a group of fairies danced in your yard last night, but the truth is that there are bacteria dancing in your soil. Fairy rings are usually the result of decaying tree roots from a long-dead tree, which is pretty cool in itself, but it can leave lasting damage to your lawn. Fairy rings can come back year after year and can grow several hundred feet in diameter.

To control fairy ring, use a rake to air the grass out and break up thatch. This will allow water to get through the water-tight fungus that is choking your grass.


Rust is so named because it looks like the rust on a car but on your grass. It appears as rust-colored patches or flecks on grass blades. The rust fungus is most active from spring through fall when temperatures are between 68 and 86 degrees F. Rust can develop in wet, humid weather but can also appear in periods of drought and high heat. Stressed grass is the most susceptible to rust. Grass types affected by rust include perennial ryegrass, tall fescue, Kentucky bluegrass, and zoysiagrass. The best way to control rust is by maintaining a healthy and vigorous lawn and following proper horticultural practices.
