How to Prevent Snow Mold on Your Lawn

When you’re in the thick of the winter season, you might not be thinking about your lawn. However, leaving large piles of slowly melting snow can cause snow mold on your grass! Read on to see Giroud’s tips for preventing snow mold so you have a great lawn this spring!

What Is Snow Mold?

Snow mold is a fungus that is common in Pennsylvania’s cool-season grasses. In General, lawn fungus occurs when grass is smothered and moist. When large piles of snow are left slowly melting, snow mold can begin to form on your lawn. It can look like gray or grayish-white circles of crusty dead grass around your yard.

Unfortunately, homeowners often don’t see the damage until the snow melts and warmer temperatures roll in. What a frustrating way to start the spring season!

How to Prevent Snow Mold

Although seasonal snowfall can’t be stopped, there are steps you can take to prevent snow mold on your lawn.

  • Clean up lawn debris before the snow falls- dead grass, leaves, and other natural matter block airflow to your grass.
  • Aerate your lawn in the fall- aeration will break up compacted soil, so water and melting snow can flow easily down into the ground rather than pooling up at the top and growing mold.
  • Don’t let snow pile up- although it can be exhausting to shovel snow all winter long, massive mountains of snow at the edges of your driveway and walkways are the perfect breeding grounds for mold!

An Important Note about Shrubs

As you shovel piles of snow, be mindful of important shrubs and plants in your garden beds. A sharp stick of a shovel can do a lot of damage to an important shrub! Also, be careful to not dump snow on top of buried plants and shrubs. Try to distribute the snow evenly around the lawn rather than moving piles into the garden.

How to Treat Extreme Cases of Snow Mold

If snow mold damage to your lawn is extensive, your Giroud Lawn Care Expert may recommend treatment and overseeding to repair it. It’s important that you schedule an inspection as soon as you see a problem because catching it early will make it easier for your lawn to successfully recover.
