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.
