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.

  • Apply pre-emergent herbicide when soil reaches 55F
  • Begin mowing when grass reaches 3 inches
  • Start irrigation if rainfall is below 1 inch/week
  • Soil test every 2-3 years — adjust lime or sulfur as needed

Summer

  • Mow at recommended height weekly
  • Water deeply 1-2 times per week (1 inch total)
  • Avoid fertilizing cool-season grasses in peak heat
  • Scout for grubs and treat if >10 per sq ft

Fall

  • Overseed warm-season lawns if thinning
  • Apply fall fertilizer (highest N application for cool-season)
  • Continue mowing until growth stops
  • Rake or mulch leaves to prevent smothering

Winter

  • Apply pre-emergent for winter weeds
  • Service mower and sharpen blades
