Dollar Spot Disease in Lawns

A fungal disease that affects lawns, primarily cool-season grasses like Kentucky Bluegrass, Perennial Ryegrass, and Fine Fescue.

Affected areas of the lawn appear as small, round, straw or tan colored spots, often resembling the size of a silver dollar.

The edges of the spots may have a reddish-brown border, making them stand out on the green grass.

In severe cases, these spots can grow and combine, forming larger patches of dead or dying grass.

The fungus Sclerotinia homoeocarpa is responsible for causing Dollar Spot disease.

Dollar Spot thrives in warm, humid conditions, making it more common during summer months

The fungus spreads through contact with infected grass blades, or by traveling through the air.

Mowing equipment, shoes, and other lawn tools can also carry the fungus, spreading the disease.

Watering your lawn early in the morning allows the grass to dry before nightfall, reducing the risk of fungal diseases.

Using a sharp mower blade ensures a clean cut, minimizing stress on the grass and promoting healthy growth.

Mow your lawn regularly to maintain a consistent height and prevent excessive growth that can weaken your lawn.

Never remove more than a third of the grass blade at each mowing to avoid stressing the lawn and promoting its health.

Dollar Spot is a common lawn disease that thrives in hot and humid weather. It can cause brown spots in your lawn.

Control the spread of Dollar Spot by adjusting your lawn care practices. This includes proper watering, mowing, and fertilization.

In some cases, a Weed Man professional may be able to provide additional solutions and recommend the best treatment for Dollar Spot.

If the Dollar Spot damage is severe, you may need to repair the affected areas with sod or grass seed.
