Dollar Spots

Dollar Spot

Type: Fungal Disease

Pathogen: Sclerotinia homoeocarpa

Appearance: Small, circular patches, often silver-dollar-sized, with bleached grass in the center and darker borders.

Risk Factors: Warm and humid conditions, compacted soil, and nitrogen deficiency contribute to dollar spot development.

Timing: Most active during periods of high humidity and temperatures between 59°F to 86°F.

How to Control Dollar Spots


Take steps to stop dollar spots before they have the chance to thrive.

  • Water Well: Your grass needs adequate water to thrive. It prefers long soakings about two to three times weekly instead of daily watering, depending on the rain levels from the week.
  • Reseed patchy spots: Grass roots go deep into the ground and take up a lot of space, taking away the valuable real estate weeds need to thrive.
  • Aerate Your Soil: Soil compaction keeps air and water from reaching the deeper levels of soil where grass roots grow, so only plants that grow nearer to the surface, like weeds, can thrive.
  • Check Your Lawn’s pH Level: If your soil’s pH level isn’t neutral (about 7.0), your grass doesn’t have the right environment to thrive, but weeds might. To balance the pH level, your soil may also need applications of lime.


  • Fungicide Application: Apply fungicides designed for dollar spot control during peak disease periods.
  • Improve Drainage: Address soil compaction and improve drainage to prevent prolonged periods of leaf wetness.
