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.

Spring

  • Apply pre-emergent herbicide when soil reaches 55F
  • Overseed bare spots once frost risk passes
  • Start irrigation if rainfall is below 1 inch/week
  • Soil test every 2-3 years — adjust lime or sulfur as needed

Summer

  • Mow at recommended height weekly
  • Water deeply 1-2 times per week (1 inch total)
  • Avoid fertilizing cool-season grasses in peak heat
  • Scout for grubs and treat if >10 per sq ft

Fall

  • Core aerate compacted areas
  • Apply fall fertilizer (highest N application for cool-season)
  • Continue mowing until growth stops
  • Rake or mulch leaves to prevent smothering
