3 Types of Winter Lawn Damage and How Spring Dethatching Fixes Them
April 10, 2025 · 4 min read
As the snow melts in Minnesota, many homeowners are greeted by a lawn that looks far from the lush green they remember. Winter can leave behind a variety of damage—from pest activity to fungal growth. Here are the three most common types of winter lawn damage we see, and how spring dethatching can help your turf bounce back.
1. Grub Damage
If you notice patches of turf that look brown and dead, or if the grass lifts up easily like a piece of loose carpet, you're likely looking at grub damage. These larvae feed on the roots during the summer and fall. You might also see areas where birds or moles have torn up the grass—they're just looking for a snack!
2. Vole Damage
Do you see narrow, winding "runways" or paths worn into the surface of your grass? That is the handiwork of voles. These small rodents spend the winter tunneling through the grass under the cover of snow, eating the blades as they go. While it looks messy, the crowns of the grass are usually still intact.
3. Snow Mold
If you see circular patches that look crusty, matted, or covered in a gray or pinkish fuzzy substance, that's snow mold. This fungal growth thrives when snow sits on unfrozen ground for long periods. It can make the grass look bleached and lifeless once the moisture evaporates.
Rejuvenate Your Turf with Spring Dethatching
The good news is that your lawn is resilient. Spring dethatching is one of the most effective ways to help your turf bounce back from winter stress. By mechanically removing the layer of dead grass, debris, and matted "thatch" that has built up, we allow the soil to finally breathe. Dethatching:
- Clears out snow mold by breaking up matted patches and improving airflow.
- Smooths out vole tracks, encouraging new growth to fill in those unsightly paths.
- Boosts nutrient uptake, ensuring that water and fertilizer reach the roots (where the grubs were busy feeding) rather than getting stuck in the debris.
A professional dethatching gives your lawn the "clean slate" it needs to green up faster and stay healthy all season long!
