Intense Heat Peaks in the Midlands

Well-Drained Loam Supports Healthy Turf
Edgefield features fine sandy loam that is naturally well-drained, providing a better physical foundation than many coastal counties. The pH of 5.46 is acidic and requires adjustment with lime to reach the 6.0-7.0 ideal range. With 63.0% sand and 13.2% clay, the soil offers a balanced texture for root development.
Managing Severe Drought in the Heat
Current data shows 59.7% of the county is in severe drought, part of a 23-week trend over the past year. Because all of Edgefield is abnormally dry, using mulch around lawn edges can help preserve soil moisture. Deep watering twice a week is more effective than daily light sprinkling in these conditions.
Starting Your Edgefield Lawn Project
Warm-season grasses like Bermuda or Zoysia are highly recommended to handle the 81 days of extreme heat. Target late spring for seeding or sodding, safely past the March 26 frost date and before the November 8 cooling. With proper soil adjustment, your lawn can thrive in this 8b hardiness zone.
