Effect of Winter in Area – Snow Mold
Now that Snowmageddon seems to be behind the North West, it is time to look for the effects the harsh winter had on all of us. Hoping that all your structure survived, Guardian would like to help you spot problems in your lawn and landscape. In this part one of the series we are going to talk about snow mold. According to the University of Minnesota, here is a couple of things to look for:
Snow mold is a fungal disease that generally appears in early spring when the snow begins to melt on the lawn. “There are two types of snow molds, gray and pink, that become active under the snow cover. Symptoms first appear in the lawn as circular, straw colored patches when the snow melts in the spring.” While the molds do not occur in the lawns every year, it most common during years when an early, deep snow cover prevents the ground from freezing, as is the case this season. It is not generally recommended to apply a fungicide, most areas that are affected by grey snow mold can be raked gently to promote the area to dry more quickly and stop the growth. Pink snow mold on the other hand is spread by spores and it is not recommend to rack the area. Here are some tips to take into consideration to avoid future problems:
- Avoid excessive applications of nitrogen fertilizer in the fall.
- Continue to mow the lawn at the recommended height until it is no longer actively growing. The taller the grass, the more likely it will mat down and encourage snow mold development.
- Rake up leaves in the fall.
- Manage the thatch layer to avoid accumulations of more than ½ inch.
- Spread out large snow piles to encourage rapid melting. Use snow fencing to minimize snow accumulation in problem spots.
