Data Story
About Lawn Care in Mathews County, Virginia
Coastal Ease in Mathews County
Mathews County scores a 56.0 on the lawn difficulty scale, placing it just ahead of the Virginia average. As part of Hardiness Zone 8a, this coastal area enjoys milder winters than the state's interior. This makes it a prime location for warm-season grasses that love the long, humid summers.
Abundant Rain and Low Heat Stress
At 51.9 inches of annual precipitation, Mathews is significantly wetter than the state average of 46 inches. It only experiences 16 extreme heat days, which is nearly half the state average, protecting grass from summer burn. A high 4,148 growing degree days ensures your lawn has plenty of energy to grow.
Sandy and Very Acidic Soil
The soil here is 59.4% sand and only 13.1% clay, leading to very fast drainage and nutrient leaching. With a pH of 5.06, the soil is extremely acidic and requires significant lime applications to support healthy turf. Homeowners should focus on adding organic matter to help the sandy soil hold onto water and food.
Short Drought Spells
Mathews has only seen 7 weeks of drought over the past year, far fewer than most Virginia counties. However, the entire county is currently labeled as abnormally dry. Because of the high sand content in your soil, your lawn will show signs of thirst faster than clay-heavy yards.
A Long, Coastal Growing Window
The frost-free season begins early on April 1 and lasts until November 10, providing a massive window for growth. St. Augustine or Centipede grass are excellent choices for the sandy, Zone 8a conditions. If you prefer cool-season grass, the mild 16 heat days make Tall Fescue a viable, year-round option.

- 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
