Data Story

About Lawn Care in Tyrrell County, North Carolina

Coastal Conditions Create a Tough Lawn Challenge

Tyrrell County presents a significant challenge for homeowners with a lawn difficulty score of 33.5, which is notably lower than the national median of 50.0. Its coastal Hardiness Zone 8b provides plenty of warmth, but residents find it more difficult to maintain green space here than in many other parts of the state.

High Rainfall and Mild Heat Patterns

The county receives 55.3 inches of annual precipitation, exceeding the ideal lawn range of 30-50 inches. With 31 extreme heat days and 4,853 growing degree days, the climate supports long periods of growth, though excess moisture can lead to fungal issues.

Overcoming Highly Acidic Soil Barriers

The soil is extremely acidic with a pH of 4.66, falling far short of the 6.0-7.0 range preferred by most grasses. While specific drainage data is unavailable, the mix of 10.6% clay and 40.5% sand requires significant lime applications to balance the chemistry for healthy roots.

Recent Dry Spells Impact Turf Health

Tyrrell County spent 26 weeks in drought over the last year, and currently, 100% of the area is considered abnormally dry. To preserve turf during these dry windows, homeowners should water deeply and infrequently rather than providing light daily sprinkles.

Start Strong with Warm-Season Grasses

Given the Zone 8b climate, warm-season varieties like St. Augustine or Bermuda are the most reliable choices. Aim to seed or sod after the last spring frost on March 29th to ensure the lawn establishes before the summer heat arrives.

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

  • Raise mowing height to reduce heat stress
  • 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
  • Overseed with ryegrass for winter color

Seasonal Breakdown

Wait until after March 29 to seed or overseed; soil temperatures should consistently reach 50-55°F. Cool summers (July averages 79.1°F) reduce heat stress — maintain regular mowing and moderate watering. With 30.8 days above 90°F annually, warm-season grasses recover faster from summer stress than cool-season types. Aerate and overseed cool-season lawns by early fall, well before November 13; this is the best renovation window. Mild winters (January averages 42.8°F) allow year-round mowing for warm-season lawns and minimal dormancy.

Watering Guidance

Tyrrell County receives abundant rainfall (55.3 inches annually), so lawns rarely need supplemental irrigation. Currently, 100.0% of the county is in moderate drought according to the US Drought Monitor. Consider reducing irrigation frequency and allowing cool-season lawns to go semi-dormant during peak heat. Standard warm-season watering of 1 inch per week is usually adequate during summer.
