Data Story
About Lawn Care in New Hanover County, North Carolina
Coastal Conditions Create Lawn Challenges
New Hanover County earns a lawn difficulty score of 33.8, making it significantly harder to maintain than the national median of 50.0. Located in Hardiness Zone 8b, local homeowners face a environment that is more demanding than the North Carolina state average of 40.8.
High Humidity and Extreme Heat
The county receives 62.9 inches of annual precipitation, which is well above the ideal 30-50 inch range and often fuels fungal growth. With 52 extreme heat days and 5598 growing degree days, lawns require aggressive mowing and careful moisture management during the long summer.
Ideal pH Meets Sandy Ground
The soil pH of 6.05 hits the sweet spot for nutrient absorption, falling right within the ideal 6.0-7.0 range. Because the soil is 72.9% sand, it drains rapidly, requiring residents to monitor moisture closely despite the high annual rainfall.
Severe Drought Despite High Rainfall
New Hanover has endured 26 weeks in drought over the past year, with 100.0% of the county currently facing Severe (D2+) conditions. To protect turf, use smart irrigation controllers and maintain a higher mowing height to shade the soil and reduce evaporation.
Seize the Coastal Growing Season
Warm-season grasses like St. Augustine or Bermuda are best suited for this 8b climate and long growing window. Aim to establish new sod or seed after the last spring frost on March 20, ensuring deep roots take hold before the November 15 fall frost.

Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.
Sandy soil drains fast — water lightly and often. Aim to keep the top 1 inch moist with 2–3 short cycles a day (~0.1 in each) until germination, then taper to deeper, less frequent watering.
Seasonal Lawn Care Checklist

- 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
