Gray and Pink Snow Mold appear as fluffy white to salmon pink mixture of fungal strands & spores visible at the edge of the patch. Usually 6-24" in diameter throughout the lawn or side-by-side. Turfgrasses are very prone to diseases when snow or ice cover persists for long periods of time in the winter, thus trapping moisture and preventing sunlight in the turf. Lightly rake the matted turf. This will increase air circulation around the grass plants and allow the grass to grow and fill in. As soon as the soil begins to thaw out, it is a good idea to aerate the turf to encourage root and rhizome growth.
