Seasonal Breakdown
Wait until after April 23 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 73.2°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 20; this is the best renovation window. Cool winters (January averages 26.1°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
With 42.2 inches of annual rainfall, established lawns typically need watering only during extended dry spells. 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.
