Dollar Spot is a foliar disease that does not affect the crown and roots of your lawn, simply put it is merely cosmetic.
Dollar Spot is characterized by small, round, straw-colored spots. Spots are generally 1-3 inches in diameter. When the pathogen is active and dew is present, a white, cottony, or cobwebby growth is visible.
The disease appears at temperatures between 60-90 °F and is favored by warm days, cool nights, and high humidity. Dollar Spot has the potential to be active from mid-May through mid-October.
Best practices in managing Dollar Spot are to water less frequently with longer deep root watering sessions. If possible, avoid watering at night and on humid days. The turf will eventually recover, and the disease will grow out on its own.
