- 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

Lawn Care Advisory: Stewart County
Lawn Verdict
Stewart 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 5,678.2 growing degree days annually, supporting vigorous warm-season lawns. High annual precipitation (52.8 inches) supports lush growth but increases disease pressure.
Seasonal Breakdown
Wait until after April 1 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 80.0°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 72.1 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 4; this is the best renovation window. Mild winters (January averages 47.1°F) allow year-round mowing for warm-season lawns and minimal dormancy.
Watering Guidance
Stewart County receives abundant rainfall (52.8 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.
