The humid subtropical climate of coastal North Carolina heavily influences the types of grass seed that can prosper here. With plenty of rainfall, the region experiences hot, humid summers and mild winters. Coupled with the sandy soil, these conditions affect how to choose the best grass seed for Wilmington, N.C.
Wilmington is presently classified under USDA growing zone 8b, having recently transitioned from 8a. Due to the heat and humidity of this area, warm-season grasses thrive. However, tall fescue, a cool-season grass, is also common in this area.
How to Choose Grass Seed
Wilmington locals can use the chart below to choose the perfect grass seed for their needs. First, determine the type of soil in your yard and the amount of sunlight it receives. Also, consider other factors such as the intended use of the yard (e.g., play area or ornamental) and maintenance needs.
After considering these factors, refer to the chart to select the best grass seed for your North Carolina lawn.
| Grass Type | Soil pH | Shade Tolerant | Foot Traffic Tolerant | Care Level |
| Bahiagrass | 5.5 – 6.5 | Low | Low | Low |
| Bermudagrass | 6.0 – 6.5 | Low | High | High |
| Centipedegrass | 5.0 – 6.0 | Moderate | Low | Low |
| St. Augustine | 6.0 – 7.5 | Moderate | Low | High |
| Tall Fescue | 5.5 – 6.5 | Moderate | Moderate | Moderate |
| Zoysiagrass | 6.0 – 6.5 | Moderate | High | Moderate |
- Soil: Start by testing your soil. The soil test will determine if your soil is acidic or alkaline, aiding your choice of a grass type suited to your yard’s conditions. Wilmington residents can get their soil tested at the New Hanover County Arboretum for $4 during peak season, but it’s free from April 1st to mid-November.
- Sunlight: Determine the amount of sunlight your yard receives. Certain types of grass require full sun, while others can tolerate shade. Consider this if you’re landscaping for shade in your yard.
- Activity: Consider how your lawn will be used. If it’s expected to experience high foot traffic from parties or kids, choose a durable grass type that can withstand the activity. For those with active pups, select the best grass for dogs.
- Care level: Think about the level of maintenance you’re willing to provide. For a low-maintenance lawn, choose a grass type that requires minimal care. If you’re into lawn care, check out our spring lawn care tips for Wilmington, N.C. for a successful summer lawn.

This cool-season grass is a good fit for the area’s climate and is often chosen because it stays green in hot weather, droughts, or heavy foot traffic. However, since tall fescue is a bunch-type grass, it cannot fill in gaps on its own and requires overseeding.
Classification: Cool-season grass
Spreads by: Produces short rhizomes but has a bunch-type growth habit
Shade tolerance: Moderately tolerant of shade
Drought tolerance: Tolerates drought well but may need extra water in prolonged dry spells
Foot traffic tolerance: Durable and well suited for moderate-traffic areas
Maintenance needs: Water 1 to 1 1/4 inches per week and overseed in the fall. It is vulnerable to brown patch. Frequent mowing.
Recommended mowing height: Set mowing height to 2 inches when grass reaches 3 inches tall
Potential for disease: Tolerant of most diseases when properly maintained
Soil pH: 5.5-6.5

Spreads by: Rhizomes and stolons
Shade tolerance: Average tolerance to shade, but requires four hours a day in direct sunlight
Drought tolerance: Highly drought-tolerant, Zoysia turns brown in dry weather but greens up with water.

Maintenance needs: Zoysia needs about 1 inch of water a week and fertilizer once or twice a year. You’ll need to dethatch your lawn every one to two years.
Recommended mowing height: Mow the lawn once a week or every two weeks, maintaining a height of 1 to 2 inches.
Potential for disease: Good disease tolerance overall
Soil pH: 6-6.5
Soil type: Well draining, some cultivars are more tolerant of a wide range of soils than others

When to Plant Grass Seed in Wilmington
The type of grass you choose will determine the best time to plant grass seed. Warm-season grasses, like Bermuda and Zoysia, should be planted in the spring, and cool-season grass, like tall fescue, needs to be planted in the fall.
- Warm-season grasses: Plant in late spring to early summer when soil temperatures reach 65-75 degrees Fahrenheit. These grasses thrive in warm weather and begin to grow rapidly as temperatures rise.
- Cool-season grasses: Plant in early fall when soil temperatures are approximately 50-60 degrees Fahrenheit. This allows the grass to establish before winter while still benefiting from the cool, damp conditions.
Cost to Seed a Lawn
How much seeding a lawn costs depends on the size of your yard, grass type, and whether you hire a pro or opt to go DIY. The cost for a pro to seed a lawn is typically between $592 to $1,768 or around $0.09 to $0.19 per square foot.
If you decide to plant grass seed on your own, you’ll pay between $149 to $449 for the seeds and any necessary equipment. Hiring a contractor to seed a large lawn will cost more than doing it yourself, but pros have the equipment and know how to get your lawn planted quickly and effectively. Plus, it can save you the time of doing it yourself.
FAQ
Can Vinegar or Baking Soda Test Soil pH?
Yes, you can use baking soda or vinegar to test the pH of your soil. Combine a fresh soil sample with water and vinegar at a 1:1 ratio. If the combination fizzes, your soil is alkaline. If there’s no reaction, the soil may be acidic or neutral.
For acidity testing, mix another fresh soil sample with water and baking soda, again at a 1:1 ratio. If this mixture fizzes, your soil is acidic. If neither of the tests produces a reaction, your soil is likely neutral.
How Do You Control Lawn Weeds?
The best way to control weeds in Wilmington is to maintain a healthy lawn. Regular mowing, proper watering, and fertilization will discourage weed growth. Applying pre-emergent herbicides can prevent weeds from growing, as well.
How Long Does it Take for Grass Seed to Grow?
The germination time for grass seed varies by type, but most grasses will start to grow within 10 to 14 days under ideal conditions.
