Abundant rainfall supports healthy green turf
The county receives 35.9 inches of annual precipitation, surpassing both the state average and the national ideal. With only 3 extreme heat days annually, the 1,614 growing degree days provide a gentle environment for cool-season grasses.
Sandy soil needs pH correction
The soil is exceptionally acidic with a pH of 4.57, well below the ideal 6.0 threshold for grass. Because the texture is primarily sand with only 1.2% clay, homeowners must add organic matter to improve nutrient retention and moisture holding capacity.
Excellent hydration with zero drought weeks
