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

Seasonal Breakdown
Wait until after March 14 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 82.1°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 74 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 15; this is the best renovation window. Mild winters (January averages 40.8°F) allow year-round mowing for warm-season lawns and minimal dormancy.

Tunica County receives abundant rainfall (56.5 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.
