Data Story
About Lawn Care in Marshall County, Mississippi
Managing North Mississippi Lawns
Marshall County scores a 31.9 on the lawn difficulty scale, placing it right near the state average of 30.9. Located in Hardiness Zone 8a, it offers a slightly cooler environment than the southern part of the state. However, it still requires more effort than the national median of 50.0.
Fewer Heat Extremes, High Rainfall
Marshall County experiences only 53 extreme heat days, which is much lower than the state average of 73. However, the 56.5 inches of annual rain still exceeds the ideal 30-50 inch range. The 4,776 growing degree days suggest a slightly slower growth rate compared to the hotter delta regions.
Balancing pH in Silty Soil
The local soil pH is 5.26, necessitating lime to reach the desired 6.0-7.0 for optimal grass health. With 14.7% clay and 22.9% sand, the soil likely has a high silt content that can become compacted. Aeration and organic amendments can help improve the soil structure for better root penetration.
Recovering from Prolonged Dryness
The county endured 28 weeks of drought over the past year, and 100% of the county is currently abnormally dry. This consistent lack of moisture can lead to dormant brown lawns if supplemental irrigation isn't used. Prioritizing water conservation techniques is essential given the recent history of extended dry spells.
Timing for the Northern Frost
The growing window is a bit shorter here, with the last spring frost on April 6 and the first fall frost on October 28. Bermuda grass is a resilient choice that handles the variable moisture and moderate heat well. Start your seeding projects in late April to ensure the ground is warm enough for germination.

- 3EstablishMay 18 – Jun 14
Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.
Silt retains moisture well — keep the seedbed consistently damp with about ¼ inch once daily, easing off if the surface stays wet to avoid damping-off.
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

Aerate and overseed cool-season lawns by early fall, well before October 28; this is the best renovation window. Cool winters (January averages 39.6°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
Marshall 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.
