What is Gray Snow Mold & What Can Cause this Lawn Disease?

Winter lawn diseases are mostly associated with wet periods and melting snow. Fescues, bluegrass, and ryegrasses may be attacked, however, bentgrasses are one of the most exposed. One of the most popular lawn diseases that occur in the winter season is gray snow mold.

Gray snow mold is caused by Typhula incarnata. This lawn disease appears as a true snow mold and you can notice it easily as it is in roughly circular bleached patches in about 60cm in diameter. Very soon, after the snow melts, the grass that it has been infected, may be surrounded by a gray or white halo of fungal growth. Keep in mind that the severity of this disease may vary and even though the grass looks deformed, gray snow mold can rarely destroy it.

These are top 4 revealing signs and symptoms of gray snow mold:

  • Large, overlapping, and irregular ring patterns
  • Tan-colored to white-grayish-colored halos or rings, in size from a few inches to several feet in a diameter
  • Crusty and matted grass
  • Destroyed roots and crowns

Helpful Tips for Preventing Gray Snow Mold

  • Mow your lawn before the first snow – Make sure to make your last mow of the growing season from 1 to 1 ½ inches shorter than you usually do as long the grass is only going to encourage the gray snow mold growth.
  • Don’t let leaves pile up – As a thick layer of leaves makes a friendly environment for gray snow mold, make sure to use the mower to mulch the leaves.
  • Don’t let snow pile up – Keep in mind that snow mold grows under the snow cover. For that reason avoid creating piles in your lawn especially when you are clearing snows from driveways and sidewalks.
  • Go easy on Nitrogen – While Nitrogen can be great for fast greening, too much of it can invite gray snow mold.
  • Repair & Reseed – In some situations, despite our efforts, discolored or dead grass may never recover. In a situation like this, scrape the infected area in order to break up the matted and crusted grass and after that repair and reseed as soon as you can.
