Moderate rainfall (30.0 inches) generally supports healthy lawns with minimal supplemental watering.
Seasonal Breakdown
Wait until after May 4 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 71.6°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 7; this is the best renovation window. Winters are harsh (January averages 11.3°F); avoid foot traffic on frozen turf and plan snow mold prevention.
Watering Guidance
Moderate rainfall (30.0 inches) means lawns benefit from weekly deep watering during summer stress. The county is currently free of drought conditions. Cool summers reduce water demand; overwatering is a bigger risk than drought stress.
