Stop Snow Mold From Eating Your Lawn

Most of us enjoy a nice patch of thick green grass under our feet during the spring and summer, but unfortunately for those people who live in areas that get thick blankets of snow, this might actually be something that they take for granted. Mold becomes a problem for some lawns during the winter time and can absolutely wreak havoc on them while that thick and beautiful blanket of snow graces your front yard. By the time it melts, you will be left with dead circular patches of grass all over and not a clue as to how they got there.

Mold is a problem generally when a thick and wet layer of snow falls on your front yard before the ground has had a chance to freeze and render the mold spores and fungus living there dormant. This means that when the blanket of snow is resting on your lawn and insulating it throughout the winter, mold is free to run amok and have a feast on it.

The symptoms of this lawn disease are typically circular patches of dead grass all over the lawn, but if the infection is severe, then you may not even be able to see these as circular patches due to the amount of grass that has been killed.

There are at least two different kinds of snow mold and these are pink and gray. The pink variety of snow mold seems to be the most dangerous of the two, as it is able to reach the roots of the grass and completely kill it. This is caused by the mold Microdochium nivale and can be anywhere from a light pink to a deep salmon-pink type color.

Gray snow mold is, as you would guess, anywhere from gray to white in color, but it is not caused by a specific mold. It is caused by molds in the genus Typhula. These molds do not affect more than the blades of grass and will not kill the grass down at the roots.

Snow mold occurs most often when a blanket of snow falls on a patch of ground that is not frozen and does not melt for an extended period of time. It can also occur, however, when fall leaves are let to cover a patch of grass for a long time. The best thing that you can do to prevent snow mold is to keep mowing your lawn as long as it keeps growing and do not fertilize your lawn less than six weeks before cold weather rolls in.
