Data Story
About Lawn Care in Shawano County, Wisconsin
Moderate Maintenance in Zone 5a
Shawano County posts a lawn difficulty score of 58.1, outperforming the national average but falling below the state mark of 64.4. Its Hardiness Zone 5a designation allows for a broader range of grass varieties compared to its northern neighbors.
Steady Rainfall and Balanced Warmth
The county receives 33.1 inches of rain annually, slightly below the state average of 34.5 inches. With 2,125 growing degree days and only 5 days of extreme heat, the climate generally supports steady, manageable grass growth.
Sandy Soils and Low pH
A high sand content of 54.7% ensures excellent drainage but requires more frequent watering to prevent turf stress. The soil pH of 5.39 is acidic, so adding lime will help move your lawn closer to the preferred 6.0-7.0 range.

Time Your Seeding for May
Kentucky Bluegrass blends perform well here, providing a lush look if given proper soil amendments. Aim to start your lawn after the typical last frost on May 13 to avoid early-season cold damage.
