About Lawn Care in Henrico County, Virginia
Favorable Conditions in Henrico
Henrico County earns a lawn difficulty score of 56.3, outperforming both the national median and the Virginia state average. Hardiness Zone 7b offers a long growing season that supports a variety of grass species. While the score is favorable, local climate extremes still demand a smart maintenance plan.
Thriving Through Summer Heat
Henrico faces 44 extreme heat days per year, which is considerably higher than the state average of 28. With 4399 growing degree days and 45.5 inches of rain, your grass grows vigorously but requires plenty of water to offset the high July temperatures. Vigilant irrigation is the key to preventing summer dormancy.
Correcting Acidic Soil Structure
The soil pH of 5.18 is quite low, requiring regular lime treatments to reach the ideal range for grass health. Your soil is composed of 59.9% sand and 14.6% clay, providing decent drainage but limited nutrient retention. Adding organic compost can help improve the soil's ability to hold water and fertilizers.
Short Spells of Drought Stress
Henrico has experienced only three weeks of drought over the past year, though the entire county is currently listed as abnormally dry. This lower historical drought frequency gives you a break compared to western Virginia neighbors. Even so, practicing water conservation now will protect your lawn if a longer dry spell develops.
Planting for a Long Season
Tall Fescue is the standard for Zone 7b, but Bermuda grass is a strong alternative for handling the county's 44 heat days. Plan to seed after the last frost on April 7 or in the late summer before the first frost on November 4. This wide window gives you ample time to establish a resilient lawn.
