Seasonal Breakdown

Wait until after April 27 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 73.5°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 21; this is the best renovation window. Cool winters (January averages 25.1°F) mean slow or dormant growth; keep debris off the lawn.
