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.

Seasonal Lawn Care Checklist

Spring

  • Apply pre-emergent herbicide when soil reaches 55F
  • Begin mowing when grass reaches 3 inches
  • Start irrigation if rainfall is below 1 inch/week
  • Soil test every 2-3 years — adjust lime or sulfur as needed

Summer

  • Mow at recommended height weekly
  • Water deeply 1-2 times per week (1 inch total)
  • Avoid fertilizing cool-season grasses in peak heat
  • Scout for grubs and treat if >10 per sq ft

Fall

  • Overseed warm-season lawns if thinning
  • Apply fall fertilizer (highest N application for cool-season)
  • Continue mowing until growth stops
  • Rake or mulch leaves to prevent smothering

Winter

  • Apply pre-emergent for winter weeds
  • Service mower and sharpen blades
  • Plan spring soil amendments based on fall test
