In Minnesota, snow mold is a common problem for lawns during long winters, especially after heavy snow accumulation and prolonged periods of freezing temperatures. Under a blanket of snow, this fungus thrives, particularly as the snow melts and traps moisture between it and the grass. While the white, fuzzy patches that appear in spring might seem like harmless annoyances, snow mold can still cause mold damage to lawns if not addressed promptly. The experts at Maier Tree and Lawn should assess and address any irregularities on your Winona, MN lawn as soon as the spring weather allows.
How does snow mold even grow during the winter?
Snow cover, cool temperatures, and the presence of stressed or compressed grass during the winter months combine to cause snow mold. As snow accumulates, it can create a humid sort of bubble beneath the surface. If the snow then remains in place for a long time, particularly in areas with a lot of freezing and thawing, snow mold can begin to develop. In fact, the fungus responsible thrives in these conditions.
What Does Snow Mold Damage Look Like?
While snow mold doesn’t completely kill your lawn, it can weaken it, stunt growth, and leave ugly patches of discolored grass that may struggle to recover. Mold damage can also leave the lawn vulnerable to other diseases and pests. After the snow melts in spring, it's important to address any visible signs of snow mold as soon as possible to ensure it doesn’t have time to spread out and cause trouble.
