High Rainfall and Few Heat Stress Days
Indiana County averages 47.9 inches of annual precipitation, which is well above the state average of 45.2. With only 8 extreme heat days, turf grass here is less likely to suffer from the mid-summer browning seen in hotter counties.
Lime Is Essential for Acidic Soil
