Turf Disease

Gray Snow Mold
Gray snow mold appears on lawns when snow melts in spring and patches of straw colored turf a few inches to a few feet in diameter can be seen. The orange sclerotia is the key to identification. As snow accumulates throughout the winter season on the lawn, it insulates the turf. If the turf is not fully dormant or cut short, gray snow mold may form. This is rarely a serious disease though it can be unsightly when you expect your green lawn to greet you as spring arrives - all you see are discolored splotches throughout the lawn.

To help keep your lawn from experiencing this, ensure that you cut the grass on the lowest setting for the last cut of the season (and on the first cut to promote growth). This will keep the blades of the grass from matting down and remaining wet. Also, if you notice gray snow mold in early spring, simply rake out the straw colored grass so your lawn can regenerate quicker.
