About Lawn Care in Northampton County, Virginia
Northampton Boasts Excellent Lawn Scores
At 66.7, Northampton County has one of the highest lawn scores in the state. This 8a zone offers a superior environment for growing a beautiful lawn compared to the national average of 50.0.
Temperate Coastal Climate
The county experiences only 16 extreme heat days, far below the state average of 28. Combined with 44.5 inches of rain, these conditions are nearly ideal for maintaining turf without the stress of constant scorching heat.
Extremely Sandy Soil Conditions
The soil is 77.3% sand, which provides excellent drainage but requires frequent, light watering and fertilization. The pH of 5.65 is relatively healthy, though a little lime can help reach the 6.0-7.0 ideal range.
Drought Resilience in Sandy Soil
Northampton has seen 10 weeks of drought in the past year and is currently abnormally dry. Because sand drains so quickly, you must be vigilant with irrigation during these dry periods to prevent root desiccation.
Maximize the Long Growing Window
Bermudagrass is highly recommended for these sandy, coastal conditions. Your primary growing season is long, starting after the March 28 frost and continuing until the first fall frost on November 20.
