About Lawn Care in Mower County, Minnesota
Mower County: A Lawn Lover's Paradise
Mower County boasts a high 80.4 lawn difficulty score, making it one of the easiest places in the state to grow grass. This score far exceeds the Minnesota average of 63.9 and the national median of 50.0.
Perfect Precipitation for Easy Mowing
The county receives a generous 36.8 inches of annual rain, well above the 30.0-inch state average. With only 5 extreme heat days per year, your lawn stays cooler and greener with less supplemental irrigation than most of the state.
Ideal pH Levels for Lush Growth
The soil pH of 6.38 is nearly perfect for turfgrass, falling right in the middle of the 6.0-7.0 ideal range. A clay content of 21.6% helps retain the ample rainfall, providing a stable foundation for root systems.
Reliable Resilience Against Dry Spells
While the county saw 6 weeks of drought last year, 0% of the area is currently experiencing dry conditions. Maintain this resilience by leaving grass clippings on the lawn to return moisture and nitrogen to the soil.
Kickstarting Your Zone 4b Lawn
Kentucky Bluegrass and Perennial Ryegrass thrive in Zone 4b. Plan your seeding projects after the May 6 spring frost and before the October 5 fall freeze to take advantage of the long growing window.
