About Lawn Care in Grenada County, Mississippi
Managing the Lawn in Grenada
Grenada County's lawn difficulty score of 22.3 sits below the state average of 30.9, indicating a challenging environment. Gardeners here must be proactive to keep turf healthy in this Zone 8a climate.
Temperate Winters and Wet Summers
The county sees 59.9 inches of annual rain, which is almost 10 inches more than the ideal maximum for lawns. However, with only 59 extreme heat days, your grass faces less temperature stress than much of the rest of Mississippi.
Correcting the Soil Base
Your soil is quite acidic with a pH of 5.16 and contains 24.8% sand. Without lime applications to raise the pH toward 6.5, your grass will likely struggle to absorb the nitrogen and phosphorus it needs.
Dealing with Persistent Drought
Grenada experienced 31 weeks of drought in the past year, and the entire county is currently abnormally dry. During these periods, allow your grass to grow slightly taller to protect the soil surface from the sun.
Grenada's Planting Timeline
Wait until after the last frost on March 28 to begin your spring seeding or sodding. Zoysia or Bermudagrass are excellent choices for this region, as they can handle the 5,453 growing degree days typical of central Mississippi.

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
