What Is Snow Mold?
Snow Mold is caused by a fungus that is active during the Winter months, underneath the snow. Generally, Snow Mold will not kill your grass, it just looks bad.
Why Do You Have Snow Mold?
Snow Mold can be a sign of one or more of the following.
- We had a lot of snow cover this past Winter.
- Your lawn wasn’t mowed short enough last Fall
- Your soil is wet and holding moisture.
- Your soil lacks good biology to combat the fungi that causes Snow Mold.
- You have a lot of problem grasses, like Bentgrass that are very susceptible to Snow Mold.
What Can You Do About Snow Mold?
There isn’t much you can do about what’s already happened, but the good news is that the lawn will recover soon on its own. A little light raking will help speed up the process, but don’t rake too aggressively because that can potentially kill the grass. If Snow Mold is really bothering you, we can do Slice Seeding for you, which will help the old grass recover and get new grass established.
How Can You Prevent Snow Mold?
To prevent Snow Mold next year, make sure you mow your lawn late into the season with sharp blades, down to about 2 inches, so the grass doesn't fold over on itself. Also, consider a beneficial treatment of Liquid Aeration in the Fall to help open up the soil and encourage beneficial soil biology. Organic Compost Topdressing will also add Snow Mold fungi fighters to help your lawn.
