Leaf spot generally begins in the summer with warmer evening temperatures and rainy weather.

Leaf spot disease used to be referred to as "melting out," but those are two different diseases caused by different types of fungi. Leaf spot is caused by Drechslera poae and tends to show up in the summer. Conditions for leaf spot to form include:

  • Warmer evening temperatures
  • Long periods of dew formation
  • Rainy weather
  • Excess amounts of nitrogen in the lawn
  • Overwatered lawn
  • Full shaded grass

Mowing the area can also cause the disease to spread as it is transmitted via spores. This disease is also spread by the wind or rainy weather.

The first signs of leaf spot disease are a visible discoloration in the lawn that is usually brown or tan in color. Upon closer examination, you will see spots on the grass blades that are purple or brown with visible decay around them.


Fighting leaf spot includes several different types of lawn treatments.

If you want to prevent leaf spot disease, the first step is to avoid mowing your lawn too closely. Longer grass and thicker blades mean that the grass is stronger and can fight off this disease.

It is also important to avoid putting too much nitrogen into your lawn. A well-seasoned lawn care expert will know exactly how much nitrogen to add to your soil and grass in order to avoid a surplus that leaf spot will love. Our lawn care treatments will help your grass be healthy enough to avoid lawn disease problems.

Fighting the initial appearance of leaf spot, however, may require the application of fungicides. We apply the fungicide to the affected areas first and then spread out from there to ensure that any nearby areas are treated for leaf spot.

The best defense against leaf spot is to ensure that your lawn does not become stressed out—in other words, keep it mowed, fertilize it properly, and aerate at least once a year.
