Minnesota lawns face crabgrass, dandelions, clover, ground ivy, and more. PeakGreen uses a two-phase approach — prevention in spring and control throughout the season. Whether you call it weed control, weed removal, or weed treatment, timing is what makes it work.
Pre-Emergent Crabgrass Prevention
Applied before soil temps hit 55°F — typically late April in southern Minnesota. Creates a germination barrier that stops crabgrass before it breaks the surface. Miss this window and you're fighting it all summer.
Broadleaf Weed Control
Systemic herbicide that moves through the plant and eliminates dandelions, clover, plantain, and other broadleaf weeds. Results visible within 7–14 days of application.
Post-Emergent Crabgrass
For crabgrass that breaks through the spring barrier. Applied while the plant is still young — mature crabgrass is much harder to eliminate. Included in all three PeakGreen programs.
Spot Treatments
Problem areas get targeted attention every application. We don't just spray and leave — if something isn't responding, we address it on the next visit.
Stop fighting weeds every summer
A consistent program prevents weed problems instead of chasing them. Free estimate for homeowners across southern Minnesota.

Owatonna's weed rules
The city expects property owners to keep weeds under control so they do not spread to neighboring lots.
- Weed and spray regularly: the city's property maintenance reminders ask owners to control weeds and keep them from spreading to other properties.
- Noxious weeds are prohibited: the Minnesota Department of Agriculture keeps a list of prohibited noxious weeds, and the city points owners to it.
- Height: keep lawns under 8 inches on built lots (18 inches on undeveloped lots).
- Reporting: anyone can file a Weed/Grass Complaint through the city's website.
- Timing beats effort: crabgrass pre-emergent has to go down before soil reaches about 55°F, usually late April. See when to apply pre-emergent and, for the persistent perennials, creeping charlie and wild violet.
