Battling Snow Molds: A Guide to Protecting Your Minnesota Lawn

As winter blankets Minnesota with its signature snowfall, picturesque landscapes may hide a silent menace beneath the pristine white cover—snow mold. This fungal disease can wreak havoc on your lawn, causing unsightly damage come spring.

This blog will explore snow mold, its potential impact on your Minnesota lawn, and, most importantly, how you can prevent and remedy this common winter woe.

What is Snow Mold and Its Impact on Your Minnesota Lawn

Snow mold is a cold-weather fungal disease that primarily affects lawns covered by snow for an extended period. Two types of snow molds, gray snow mold (Typhula spp.) and pink snow mold (Microdochium nivale), can strike when conditions are right. Minnesota’s long and frigid winters make it a prime location for snow mold infestations.

Gray snow mold appears as circular patches of grayish, matted grass, resembling a spider web. On the other hand, pink snow mold manifests as pink or salmon-colored patches on the lawn. Both varieties can cause significant damage, including dead patches and weakened grass, making your lawn susceptible to other diseases.

Tips to Resolve Snow Mold Infestation and Prevent it From Coming Back

Snow mold is a common concern for Minnesota homeowners, but with proactive measures and care, you can minimize its impact on your lawn. Follow the tips to resolve snow mold issues and prevent future infestations. 

Rake and Remove Debris: Before the first snowfall, clear your lawn of any debris, such as leaves and thatch. This helps prevent snow mold from finding shelter in these organic materials and infiltrating your grass.

Mow at the Right Height: Keep your lawn slightly shorter in the fall to discourage snow mold growth. Longer grass provides a cozy environment for the fungus to thrive, so maintaining a proper mowing height is crucial.

Fertilize Smartly: Avoid excessive fertilization in the fall, as it can stimulate grass growth that is more susceptible to snow mold. Instead, use a slow-release fertilizer in late fall to nourish your lawn without encouraging excessive growth.

Promote Air Circulation: Good air circulation is key to preventing snow mold. Trim back overhanging branches and allow air to reach the grass. Proper soil aeration can also enhance air circulation and reduce the risk of snow mold.

Winterize Your Lawn: Give your lawn a final cut before winter. Trimming the grass slightly shorter than usual can prevent snow mold from taking hold during the colder months.

Keep the Lawn Dry: After winter storms, gently remove snow from the lawn to prevent it from compacting into a dense layer. This helps minimize the moisture that can lead to snow mold development.

Consider Fungicide Treatment: In severe cases or if your lawn has a history of snow mold, consider applying a fungicide in late fall. Consult a landscaping company or pest control to determine the most suitable product for your situation.
