How to Treat Snow Mold in Lawns

Snow tends to blanket Southeast Michigan lawns for a good chunk of the winter. So when the snow finally melts in the spring, it can be a reveal to some degree — and what’s beneath this coverage is not always the healthy, green lawn you remember from fall.

One of the most unpleasant of these finds is circular patches of matted grass with a white or gray webbing, otherwise known as snow mold. A freeze-tolerant lawn fungus, snow mold grows in cold, snowy conditions and, more specifically, forms when snow or wet leaves remain on a lawn for too long. While remaining active throughout the winter months, signs of snow mold are only visible in the springtime after the snow melts — meaning it has more time to go unnoticed and impact a lawn’s health.

While prevention is always the best option for snow mold, there are steps you can take to treat snow mold already in your yard. The route you take depends on the severity of the lawn issue.

When Snow Mold is Relatively Minor…

When dealing with snow mold infections on a more minor scale, you can use a rake to lightly comb through the infected area(s) of grass. Without causing damage to other areas of your lawn, this technique will help dry out the infected area (as it has more exposure to sunlight) and prevent further growth of the fungus. While this will help the lawn repair itself, overseeding can be performed on top of this step if there is a need to fill in any infected bare spots afterward.

When Snow Mold Is More Severe…

In the case of more severe snow mold outbreaks — where snow coverage tends to last for an extended period of time — professionals like Lush Lawn can apply a fungicide to counteract the lawn issue and curb future growth. These fungicides are most effective when applied in the fall, specifically in October or November, so they can not only treat existing problems but also provide protection against snow mold growth throughout the duration of the winter season. This helps prevent the recurrence of snow mold, saving you time and headaches in the long run.

Differentiating Between the Two Varieties of Snow Mold

It’s important to note that there are two varieties of snow mold: gray snow mold and pink snow mold. While both types are active underneath snow coverage, pink snow mold is recognized as the more severe form as it can invade and destroy grass crowns and roots, whereas gray snow mold tends to only damage the leaf blades of grass. As their names suggest, pink snow mold can be identified by its white-pinkish appearance and gray snow mold by its white-grayish look.
