Data Story
About Lawn Care in Preston County, West Virginia
Managing Lawns in a Rugged Climate
Preston County's lawn difficulty score of 48.6 indicates it is more challenging than both the state and national averages. Homeowners in this Zone 6b region must be diligent to maintain healthy turf in these conditions.
Abundant Rainfall Keeps Lawns Hydrated
The county receives a generous 53.3 inches of rain annually, the highest among its neighbors. Very few extreme heat days (only 3 per year) mean your grass is rarely stressed by temperature, though it may stay perpetually damp.
Acidic Soil with Significant Clay
A soil pH of 5.02 requires regular lime treatments to bring it closer to the 6.5 ideal for most grasses. With 14.5% clay and 23.4% sand, the soil provides a decent structure but can become compacted if not aerated regularly.
Half the Year Spent in Drought
Despite high rainfall totals, the county experienced 26 weeks of drought over the past year. Currently, 4% of the area is abnormally dry, so keeping a rain barrel is a smart way to bridge those sudden dry gaps.
Wait for the Late Spring Thaw
Frost persists until May 7 in Preston County, so avoid the temptation to seed too early in the spring. Tall fescue is a resilient choice for this area, providing the durability needed for the 2,637 growing degree days.
