Lawn disease and fungus can quickly damage turf, leaving thin, discolored patches and stressed grass in Nashville and Middle Tennessee. Most lawns are susceptible to common fungi such as Brown Patch, Dollar Spot, and Leaf Spot, especially during humid, warm months.

Many diseases occur on turfgrasses in the Nashville and Franklin area and virtually all lawns will be infected with some type of lawn disease fungus. Throughout Middle Tennessee the most common fungi or lawn diseases are: Brown Patch, Dollar Spot and Leaf Spot. The severity of damage and repeat occurrences can be controlled with fungicide treatments.
Free water on leaves and grass blades with optimum temperatures create an environment for most fungi to cause disease and damage. We live in an area where humidity plays a key role for spreading most fungi causing brown patch and leaf spot diseases. Many times the symptoms and presence of a disease are thought to just be drought or heat stress, this is a very common and costly mistake. It will not get better with additional watering, in fact, it could get much worse. Summertime is when most fungus growth causes damage.
We recommend being proactive because the chances of getting a lawn disease in our area is very high. Timing is very important when controlling a lawn disease. No worries, we know exactly what to do and when to do it! A broad spectrum fungicide can control most fungus that cause lawn disease.
