We’ve had our fair share of weather whiplash this month, but one thing is clear, our lawns are loving the moisture and greening up fast. That fresh green carpet makes it hard not to jump right in and start working on the lawn. In northern Minnesota, though, a little patience goes a long way and knowing what to do, and what to skip, can save time and trouble later in the season.
What to Do
Rake lightly.
Once the soil is no longer soggy, gently rake to remove leaves, debris, and matted grass, especially where snow mold is visible. This improves air flow and supports natural recovery. Avoid aggressive raking, which can damage soft turf and wet soil.
Be patient with snow mold.
Gray or pink patches look alarming but rarely kill grass. Light raking and time are usually all that’s needed. Fungicides applied in spring won’t help.
Mow early, but carefully.
When grass reaches about 3½ to 4 inches and the ground is firm, mowing can help dry the lawn. Keep blades sharp and mower height high. Never mow wet turf.
Overseed only where needed.
If winter left bare patches, small scale overseeding can help once soil temperatures reach about 50°F. Keep expectations realistic, spring seedings face stiff weed competition. Larger overseeding projects are best saved for late August or early September.
What to Skip
Rolling the lawn.
Rolling compacts wet soil and damages roots. Frost heaved areas usually settle on their own as soils dry.
Early spring aeration.
Unless soil compaction is severe, spring aeration does more harm than good by stressing turf and encouraging weeds. Late summer or fall is the ideal time.
Heavy early fertilization.
Fertilizing too early promotes leaf growth before roots are ready, increasing disease risk and reducing drought tolerance. Wait until grass is actively growing, usually mid May, or plan to fertilize more heavily in fall.
Trying to fix everything at once.
Spring is not the time for dethatching, multiple treatments, or aggressive weed control. Those efforts often backfire in our climate.
Spring Lawn Care Takeaways
- Wait until soil firms up before working the lawn
- Rake gently; avoid compacting wet soil
- Mow high and only when grass is dry
- Overseed bare spots only after soils warm
- Save major lawn projects for late summer or fall
Spring is a recovery season, not a renovation season. Lawns that are lightly cleaned up and left alone often outperform those that are heavily “worked.” Patience now pays off all summer long.
