Southern Challenges for Crawford Lawns
Crawford County's lawn difficulty score of 64.6 is below the state average of 71.0, indicating extra effort is required. Homeowners in this Zone 6b region must work harder to overcome heat and soil acidity.
Heat Stress and High Rainfall
The county faces 31 extreme heat days, significantly more than the Indiana average of 20. While 51.0 inches of annual rain helps, the high 4097 growing degree days mean grass grows fast and requires frequent mowing.
Acidity and Drainage Considerations
The silt loam soil has a pH of 5.81, which may limit the availability of key nutrients like phosphorus. Because the soil is somewhat excessively drained, the combination of heat and fast runoff makes summer hydration critical.
Consistent Moisture in Recent Years
Despite 100% of the county currently being abnormally dry, it only experienced 3 weeks of drought over the last year. This relative stability allows for more flexible watering schedules compared to the northern counties.
Selecting Heat-Tolerant Turf
Tall Fescue is a top recommendation for Crawford County to handle the 31 annual heat days. Use the window between April 17 and October 19 to establish your lawn before the frost seasons begin.
