Lawn Care Advisory: Clay County
Lawn Verdict
Clay County sits in USDA hardiness zone 6a, a transitional zone where cool-season grasses dominate but some warm-season varieties can survive. with winter lows reaching around -10.0°F. and 3,484.7 growing degree days, sufficient for most common turfgrasses. Moderate rainfall (28.6 inches) generally supports healthy lawns with minimal supplemental watering.
Seasonal Breakdown
Wait until after April 19 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 76.4°F) reduce heat stress — maintain regular mowing and moderate watering. With 34.4 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 20; this is the best renovation window. Cool winters (January averages 25.8°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
Moderate rainfall (28.6 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.
