Spring in Minnesota arrives on its own schedule — sometimes March, sometimes late April. But regardless of when the snow clears, the work order for your lawn stays the same. Here's a practical checklist to get your Twin Cities lawn off to a strong start this season.
Step 1: Wait Until the Soil Firms Up
Before you do anything, let the soil dry out. Walking on a waterlogged lawn in early spring compacts the soil and damages the crown of grass plants that are just waking up. If you sink more than half an inch when you step, wait a few more days.
Signs it's safe to walk:
- Soil doesn't sink or squish underfoot
- No standing water in low spots
- Frost has fully left the ground
Step 2: Clean Up Winter Debris
Once the ground is firm, give your lawn a thorough cleanup:
- Rake away matted leaves and dead grass. Heavy leaf cover left over winter can smother grass and promote snow mold.
- Remove sticks, branches, and any salt-damaged grass near driveways and sidewalks.
- Check for vole damage. If mice or voles were active under the snow, you may see brown, winding trails through the turf. These areas will need overseeding once the lawn greens up.
Step 3: Assess Winter Damage
Walk the entire lawn and take inventory:
- Bare spots — caused by foot traffic, de-icing salt, or disease
- Thin areas — where grass thinned out over winter
- Snow mold patches — circular gray or pink patches, usually in shaded areas
- Frost heaving — small humps where roots were pushed up by freeze/thaw cycles
Note locations of problem areas so you can address them with overseeding once soil temperatures allow.
Step 4: Apply Pre-Emergent Weed Control
This is your most time-sensitive task of the spring season. Pre-emergent herbicide creates a barrier in the soil that stops crabgrass seeds from germinating — but it only works before germination begins.
In the Twin Cities, the application window is typically mid-April through early May when soil temperatures at 2 inches reach 50–55°F. Learn more about our weed control program and why timing is everything.
Step 5: Apply Spring Fertilizer
Once soil temps hit 50°F and your grass is actively growing, it's time for the first fertilizing application of the season. For most Twin Cities lawns — Kentucky bluegrass, fine fescue, perennial ryegrass — that means late April to mid-May.
Use a slow-release nitrogen formula to feed your lawn steadily without causing a surge of disease-prone growth.
Step 6: Repair Bare and Thin Spots
Once the threat of hard frost has passed, you can begin overseeding thin or bare areas. Use a grass seed blend appropriate for your lawn's conditions.
Key overseeding tips:
- Loosen the soil surface before seeding
- Keep the seeded area consistently moist until germination
- Hold off on pre-emergent in areas you plan to overseed — it will prevent grass germination too
Step 7: Adjust Your Mower
Before the first mow of the season:
- Sharpen the blade. A dull blade tears grass instead of cutting it cleanly, leaving ragged tips that brown out and invite disease.
- Set the deck height. For Minnesota lawns, mow at 3.5 to 4 inches throughout the growing season. Never remove more than one-third of the blade height in a single mow.
- Check the drive belt and oil if it's been sitting all winter.
