How to Get Rid of Common Lawn Diseases

Patch Lawn

No matter how diligently you tend your lawn, you’ll eventually experience some form of lawn disease. That doesn’t have to be the death of your green grass, though. Here are several common lawn diseases, how to spot them, and how to get rid of them.

Southern Grass Diseases

Southern grasses include Bahia, Bermuda, Centipede, St. Augustine, and Zoysia. There are also Northern grass varieties that may experience diseases other than the ones listed below, but these types of grasses are rare in the southeastern U.S.

Brown Patch

Brown patches usually occur in the summer, and they are usually a circular shape. Eventually, the grass becomes tan or brown in this area. Some common treatments include applying a fungicide and watering the grass early in the morning.

Dog Spot

Dog spot isn’t actually a lawn disease, but it’s often mistaken for one. Dog spots show up as small circles of brown or yellow grass. It’s caused by dog urine, and it is best avoided by preventing dog urination in your yard. If this can’t be avoided, try to train the dog to use one area of the yard, and water the spot thoroughly to prevent stains.

Slime Mold

Slime mold usually looks like a white or gray powder on your lawn, and it appears during wet weather from spring to fall. Thankfully, this mold isn’t harmful, so a simple mowing and raking can remedy the problem.


Pythium is usually quite noticeable. The grass starts thinning, and numerous brown or yellow patches will develop. This is a form of root rot, so the best treatment is to increase drainage throughout your yard and make sure that you are not over watering.
