Overcoming Heat in Dubois County
Dubois County has a lawn difficulty score of 70.1, making it slightly more challenging than the state average. Its Zone 6b designation allows for a wider range of grass types but brings more intense summer heat.
High Rainfall Meets Intense Heat
Lawns receive 51.7 inches of rain annually, which is above the state average and the ideal range for turf. However, 31 extreme heat days put significant stress on cool-season grasses compared to the state average of 20.
Acidic Soils Need Monitoring
The soil pH of 5.88 is slightly acidic, so adding lime may be necessary to reach the ideal 6.0-7.0 range. The balanced mix of 17.6% clay and 17.2% sand provides a stable texture for root growth.
Abnormally Dry Conditions Persist
Although the county only had 3 weeks of drought last year, the entire area is currently considered abnormally dry. Keep your mower height high to shade the soil and reduce water evaporation during heat waves.
Choose Heat-Tolerant Turf Varieties
Tall Fescue is highly recommended for Zone 6b because it handles the 31 annual heat days better than other varieties. Plan your seeding between the April 25th last frost and the October 15th first frost.
