What is Snow Mold?
Snow mold is a disease, which is caused by a fungus, and is active in the winter, typically underneath the snow. It will become visible to you in the early spring as the snow melts. It is often seen as circular patches of matted grass, which appears to be dead (don’t worry, your grass didn’t die over the winter). It will often have webbing of gray or pink. When the webbing isn’t present, you may instead see brown spots that can be slimy in appearance.
What are Some Causes of Snow Mold?
Although it is referred to as ‘Snow Mold’, snow does not always need to be present for Snow Mold to occur. It can also grow under leaves that were not raked and removed from your lawn, or under tall grass that was not mowed late enough into the Fall. All of these types of ‘cover’ retain the moisture in the ground that allows for Snow Mold to grow.
What Can be Done to Prevent Snow Mold?
The best thing that you can do is to properly prepare your lawn for the Winter.
- Mow your lawn into the Fall until it stops growing.
- Make sure that your lawn’s final cut of the season is at a height of 2-3″.
- Rake and remove all leaf debris from the lawn.
- Have an aeration service, which will decrease thatch, allowing for air circulation.
- Have a properly timed Fall fertilization service.
Always remember that a healthy lawn is less susceptible to disease.
What Can be Done to Repair Snow Mold?
The good news is that, with regular mowing and fertilization, most of the time the areas of your lawn which have been affected by Snow Mold will recover on their own, it just takes some time. To speed up the recovery, the affected areas should be lightly raked, which will help the air to circulate and allow the grass to dry. Do not rake vigorously as that can kill the grass.
In extreme cases, when all other methods of recovery have failed, your lawn may need to have an application of fungicide to stop the growth of the disease, and have the affected areas reseeded.
