Warmer Days Drive Higher Mowing Needs
With 2,751 growing degree days and 13 extreme heat days, Clinton County is slightly warmer than the state average of 11 heat days. Annual precipitation of 41.5 inches provides a solid foundation, though it is lower than the 45.2-inch state benchmark.
Managing Well-Drained Silt Loams

Resisting Extended Dry Conditions
The county endured 24 weeks of drought over the past year, and the entire area is currently experiencing abnormally dry conditions. Maintain a mowing height of 3 inches or more to shade the soil and retain moisture during these stretches.
Seeding for Clinton’s Climate
Perennial ryegrass and fine fescues are excellent choices for these well-drained soils. Aim to finish your primary lawn work between the spring frost on April 30 and the onset of winter dormancy around October 21.
