Dealing with Lawn Diseases

Many different diseases can affect lawns in Florida, including rust, brown patch, take-all root rot, and several different types of leaf spots.

Keep an eye on the overall quality of your lawn. If discolored areas appear, this may be a sign of disease.

However, brown or yellow areas can also be caused by other factors like drought or cold damage. Don’t apply any chemicals unless you know what’s really going on.

You can take a sample of grass from the affected area to your local Extension office for identification.

And remember that one of the best ways to prevent disease is to maintain your lawn properly. Follow the UF/IFAS recommendations for mowing, watering, and fertilizing to help ensure you have a strong, healthy, Florida-Friendly lawn.
