You may have noticed round white, gray or pink fuzzy patches on your lawn early this spring. This is called snow mold. When the conditions are just right, turf grasses develop this disease during the winter and we find it once the snow melts.
Patches can be as small as a few inches across or several feet wide.
Often the grass appears matted where the snow mold develops. Snow mold doesn t happen every spring and doesn t affect every lawn. It thrives during years when it snows early and a lot. It also is more of a problem when our winter hits quickly while the ground is still warm and the grass isn t fully dormant. The good news is that snow mold generally doesn t do much lasting damage.
