Lawn Verdict

Seasonal Breakdown
Wait until after April 13 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 76.5°F) reduce heat stress — maintain regular mowing and moderate watering. With 38.5 days above 90°F annually, warm-season grasses recover faster from summer stress than cool-season types. Aerate and overseed cool-season lawns by early fall, well before October 22; this is the best renovation window. Cool winters (January averages 29.6°F) mean slow or dormant growth; keep debris off the lawn.
