Mold in the Winter

If you live in an area that gets a lot of snow cover during the winter, but it thaws out during the spring, you might be familiar with this problem. Sometimes there can be a quite unwelcome guest underneath all that beautiful snow and you are not likely to find out that it is there until after the snow has already thawed and it has already done the damage it came to do.

If a blanket of snow fails to melt for quite a while after it has fallen, then you might have to deal with mold after it finally does begin to thaw out. When a thick and wet blanket of snow settles on ground that is not frozen, snow mold becomes quite a problem. It begins to decompose the grass under the snow and after the snow begins to melt, it is usually too late to do anything about it.

The main symptom of snow mold is typically a large number of circular patches of deceased grass that can be between 3 to 12 inches in diameter. In some of the most extreme cases, these patches might not look like circles at all because most of the grass on your lawn has died. When pink snow mold has matured, it takes on a pale pink to salmon-like color. This is caused by the mold Microdochium nivale. This is the most serious kind of snow mold because it can completely kill the roots of the grass it affects if it is not treated as soon as possible.

Gray snow mold is caused by different species in the genus Typhula and can be colored from gray to white. These molds usually do not cause damage to any other part of the plant than just the blades. The root usually remains unaffected.

Snow molds tend to grow in temperatures just above freezing and in semi-wet conditions. While it is most commonly associated with snow cover, it can also occur when fall leaves cover a certain spot on the lawn for a long period of time. Kentucky bluegrass-type grasses are less likely to suffer as much damage as others.

If you want to prevent snow mold from growing on your lawn, do not fertilize it less than six weeks before the cold weather begins to roll in and the grass dies. Also, as long as your grass is still growing, you should continue to mow it.
