About Lawn Care in Iredell County, North Carolina
Iredell's Favorable Growing Environment

Amending Sandy, Acidic Soils
The local soil pH of 5.61 is acidic and requires lime to reach the ideal 6.0-7.0 range for most grasses. A high sand content of 57.8% ensures drainage but may require more frequent nutrient applications to keep the lawn healthy.
Navigating Severe Drought Conditions
Current data shows 100% of the county in severe drought, following 24 weeks of drought over the past year. Homeowners should focus on deep watering and maintaining a higher mowing height to protect the soil from moisture loss.
Best Grasses for Iredell's 8a Zone
Warm-season varieties like Bermuda or Zoysia are excellent choices once the last frost passes around April 16. Start your seeding or sodding in late spring to take advantage of the warming soil and long growing season.
