Warm Summers and Long Growth
With 29 extreme heat days and 3,858 growing degree days, lawns here face more heat stress than the Indiana average of 20 days. These conditions favor grass types that can withstand sustained temperatures above 90°F.
Managing Acidic Soil Profiles
The soil pH of 5.72 is slightly acidic and below the ideal 6.0 range, suggesting that a lime application may be necessary. While local drainage data is limited, the soil's 18.5% clay content suggests moderate moisture retention.
Consistent Moisture Despite Dryness
Scott County has seen only one week of drought in the past year, though the entire county is currently listed as abnormally dry. Monitoring soil moisture is critical when heat days climb to protect your lawn's root system.
Maximize the Growing Season
Zone 6b is ideal for Turf-Type Tall Fescue, which handles heat better than bluegrass. Start your seeding projects after the April 18 frost to ensure a lush lawn before the fall frost on October 20.
