Snow Mold


Snow mold is most common to Kentucky Bluegrass and Fescues in regions where snow falls and sits on the lawn for extended periods of time.


  • Yellow, tan, or salmon-colored water-soaked patches that measure 1 to 8 inches or more in diameter.
  • Pale pink around the edges.
  • Spores are produced in white or salmon-colored sporodochia that are found on the dead tissue.
  • Blighting can occur in streaks caused by spores tracking on the wheels of the equipment.

Conditions Favoring Disease:

  • Typically occurs in the early spring.
  • Can also occur on cool-season turfgrass in mild winter climates.
