Local gardeners generally face fewer hurdles than their neighbors in harsher climates.
Ample Precipitation Meets Moderate Summer Heat

Balanced Soil Chemistry for Easy Growth
Your soil pH of 6.62 sits right in the sweet spot for nutrient uptake in most turf varieties. While official drainage data is unavailable, the 19.4% clay and 31.5% sand composition suggests a relatively stable foundation. You likely need minimal lime or sulfur adjustments to keep the soil chemistry productive.
Managing a Lingering Year of Dry Spells
The county spent 37 weeks in drought over the last year, with 100% of the area currently classified as abnormally dry. While severe drought levels currently stand at 0.0%, consistent irrigation remains vital to protect roots. Focus on deep, infrequent watering during early morning hours to maintain resilience.

Seasonal Breakdown

Cool summers (July averages 75.7°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 15; this is the best renovation window. Cool winters (January averages 25.2°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
Moderate rainfall (30.4 inches) means lawns benefit from weekly deep watering during summer stress. Currently, 100.0% of the county is in moderate drought according to the US Drought Monitor. Consider reducing irrigation frequency and allowing cool-season lawns to go semi-dormant during peak heat. Standard warm-season watering of 1 inch per week is usually adequate during summer.
