About Lawn Care in Kenosha County, Wisconsin

Kenosha Lawns Benefit from Lake Influence

Kenosha County scores a 71.0 for lawn difficulty, outperforming the state average of 64.4. Located in Hardiness Zone 5b, it offers a milder climate that is conducive to diverse grass types.

High Heat and Warm Winters

With 2,710 growing degree days and 10 extreme heat days, Kenosha is warmer than much of Wisconsin. The 35.7 inches of annual rainfall supports this extra growth, though the heat requires more attentive summer watering.

Rich Silt Loam Foundations

The soil pH of 5.86 is very close to the ideal range, while the silt loam texture provides excellent moisture retention. Moderately well-drained conditions help maintain 16.0% clay and 31.3% sand for a robust root system.

Managing Dry Southern Spells

Despite 14 weeks of drought last year, the county currently has 100% abnormally dry coverage. Homeowners should utilize mulch-mowing to retain soil moisture during these frequent dry periods.

Kenosha's Extended Planting Window

The growing season is long, starting April 28 and lasting until October 19. This gives you plenty of time to establish heat-tolerant turf like Tall Fescue blends.

Seasonal Lawn Care Checklist

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

Winter

  • Avoid walking on frozen turf
  • Service mower and sharpen blades
  • Plan spring soil amendments based on fall test
  • Keep lawn clear of debris
