Gray Snow Mold

How to Identify Gray Snow Mold

The symptoms of Gray Snow Mold are evident after snow melts. It causes light brown, gray and straw-colored patches that measure less than 10 inches in diameter and can increase to several feet.

Why Is Gray Snow Mold a Problem for Your Lawn?

Snow cover is usually necessary for this lawn disease to cause damage and is most severe when snow cover lasts more than 90 days. The fungus is only active and can spread when the temperatures remain below 45 degrees. Once it warms, your grass will return to its healthy, green color.
