Summer 2020 is finally in full swing after an unusually cool and wet spring. The summer heat and humidity are great for warm-season grasses, but the season also can prove challenging for cool-season turfgrasses, which most of us have in our yards.
Dollar spot is a common fungal turfgrass disease that appears as small silver dollar-shaped circles and can spread throughout a lawn. Humid days followed by cool nights create heavy dew on the grass, keeping grass blades wet for long periods of time – a perfect environment for this pathogen to thrive and spread.
The good news is the affected turf will recover when the humidity drops, and the temperatures begin to cool. With a good lawn application program of proper fertilization, followed by a fall aeration and overseeding, your lawn will look good as new.
