Extreme Heat and High Moisture
The county records 81 extreme heat days—one of the highest in the state—and 62.1 inches of annual rain. These conditions, paired with 6,177 growing degree days, create a high-pressure environment for weeds and lawn diseases.

Seasonal Lawn Care Checklist
Spring
- Apply pre-emergent herbicide when soil reaches 55F
- Begin mowing when grass reaches 3 inches
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Raise mowing height to reduce heat stress
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
- Overseed warm-season lawns if thinning
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
- Apply pre-emergent for winter weeds
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Overseed with ryegrass for winter color

Lawn Verdict
Copiah County falls in USDA hardiness zone 8b, a favorable range for both cool- and warm-season grasses. with winter lows reaching around 15.0°F. and 6,176.85 growing degree days annually, supporting vigorous warm-season lawns. High annual precipitation (62.1 inches) supports lush growth but increases disease pressure.
Seasonal Breakdown
Wait until after March 14 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 81.3°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 80.9 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 November 16; this is the best renovation window. Mild winters (January averages 48.0°F) allow year-round mowing for warm-season lawns and minimal dormancy.
Watering Guidance
Copiah County receives abundant rainfall (62.1 inches annually), so lawns rarely need supplemental irrigation. 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. High heat accumulation means warm-season grasses use water aggressively — monitor soil moisture regularly.
