What Is Dollar Spot?

Dollar spot is a fungal lawn disease that, true to its name, appears as silver-dollar-sized spots on the grass. It can attack both warm-season and cool-season grasses, and it is caused by the fungus Clarireedia jacksonii. Dollar spot thrives from late spring to fall, and especially loves high humidity and temperatures in the low 80s. Causes include mowing too low, lack of fertilizer, excess thatch and overwatering.
