As the snow melts, we are seeing a lot of lawns with evidence of snow mold. The snow mold looks like an opaque film of slime that has matted down the grass, as seen in the images below.
The conditions that favor the disease are:
- abundant moisture, and
- snow cover on unfrozen turf or melting snow.
The recommended treatment for the mold is to lightly rake the grass to break the slime barrier which will allow the air to circulate around the blades. If left untreated the snow mold could cause the grass to die. A fertilizer treatment will help the recovery of the affected areas.
