Pink Snow Mold

A cool-weather lawn disease that leaves pink-tinged, matted patches in your grass, even without real snow.

What it looks like

Round pink-to-tan patches up to about a foot wide. They look water-soaked and matted down when wet, and you may spot a faint pink, thread-like growth at the edges on cool, humid mornings.

When it shows up in the Triangle

Shows up late fall through winter and into early spring. NC's mild, wet winters give it the cold-and-damp conditions it needs, so you don't need actual snow to see it.

Where you’ll see it

Affects cool-season lawns.

What you can do

  • Skip heavy nitrogen feedings in late fall
  • Improve drainage in low or soggy spots
  • Keep air moving by trimming back overhanging branches or shrubs
  • Rake up fallen leaves and debris before winter
  • Don't let clippings or leaves mat down on the lawn surface
