About Lawn Care in Florence County, South Carolina
Managing High-Maintenance Turf in Florence
Florence County scores a 30.3 for lawn difficulty, indicating a tougher-than-average environment compared to the state's 35.1. Situated in Hardiness Zone 8b, the county faces high temperatures and fast-draining soils. Homeowners here must be proactive to maintain a lush, green landscape.
Long, Hot Summers Drive Turf Growth
The county sees 71 extreme heat days, which is higher than the state average and stresses traditional lawns. Precipitation is strong at 48.2 inches annually, but the 5839 growing degree days mean grass grows fast and requires frequent mowing. Irrigation needs are constant when temperatures regularly exceed 90°F.
Thriving in Well-Drained Sandy Soils
Florence features sandy soil (79.0%) that is officially classified as well-drained, preventing root rot but requiring more water. The pH of 5.18 is quite acidic, so regular soil testing and liming are necessary for nutrient uptake. With only 8.2% clay, the soil lacks the natural ability to hold onto fertilizers.
Recent Relief from Severe Drought Stress
While 100% of the county is abnormally dry, only 8.7% currently experiences severe drought, a major improvement over neighboring counties. Still, Florence has weathered 25 weeks of drought in the past year. Use rain barrels to capture some of those 48.2 inches of annual rain for use during the hottest weeks.
Choosing the Right Grass for Florence
Centipede grass is a popular choice here due to its tolerance for the acidic, sandy conditions found throughout the county. The growing window opens after March 20 and stays active until the first frost on November 13. Focus on soil amendments now to boost your lawn's health before the heat of July arrives.
