Dollar Spot

Dollar spot is a fungal disease that affects turfgrasses in Florida.

It starts by causing tan-colored lesions on individual leaf blades. As the disease progresses, it creates round, straw-colored patches in the grass that start out the size of silver dollars, but can spread up to six inches or more in diameter.

Dollar spot is mainly a problem from fall through spring, especially in grasses that aren’t getting sufficient nitrogen. Several approved fungicides can be used to treat current infestations.

Because environmental conditions play a big role in the onset of disease, you can prevent future problems by following recommended rates for watering and fertilizing, and by watering your lawn only during the early morning hours.
