Snow Mold – What is it and how to prevent it

How to prevent snow moldWith winter fast approaching we all know what that means: snow, and probably lots of it. Lawns in the midwest could be covered in the white stuff for months. This means, come springtime, we may have a problem: snow mold.

What is snow mold?

Snow mold is a fungus that grows in circular patches on your lawn. It typically appears after the snow melts in late winter or early spring, but doesn’t always require snow to form. It comes in two varieties: Gray (Typhula blight) and Pink (Fusarium patch).

What does snow mold look like?

1. Gray snow mold

Gray snow mold is the less destructive of the two. It will appear in circular patches of flattened, discolored grass with a gray web of fungus growing over top. Typically, it only damages the blades of the grass, not getting down into the roots.

2. Pink snow mold

Pink snow mold is the more serious of the two and it doesn’t even need snow to form. After an extended period of cool wet weather, usually in the fall, you may start to notice red/brown or orange spots appearing on your lawn. These will grow as winter progresses until it takes over large portions of your lawn. This mold is worse than the gray variant because it will go after the crowns and roots of your grass, effectively killing it.

Tips for snow mold prevention

Prevention is the key to eliminating snow mold. There are a number of methods that have proven successful in the battle against the mold:

1. Fungicide treatment

The best way is to have your lawn professionally treated with a fungicide. This is ideally done in the late fall, before the first snow of the year. This should protect your lawn throughout the winter and into the spring. LawnMatters offers an excellent snow mold prevention treatment.

2. Don’t over water your lawn

Mold thrives on moisture so it is important to ration the amount of water you give your lawn as the temperatures drop. Giving your grass the bare minimum that it requires is another great way to prevent snow mold.

3. Continue to mow your lawn in fall

Make sure that you are mowing your lawn throughout the fall. Keeping the grass between 2.5 – 3 inches will make your lawn less susceptible to disease and mold. Your final mow of the year should be kept short at 2″.

4. Clear your lawn of piles of leaves and snow

In the fall it’s important to remove any piles of wet leaves. This will reduce the amount of unnecessary moisture building up on your lawn.

The same goes for piles of snow. When shoveling your driveway or sidewalk try to avoid making large piles of snow in your lawn as they will take a much longer time to melt, offering more time for the snow mold to develop.
