Wet Climate Sustains Turf Growth
The county sees 47.0 inches of precipitation annually, providing the heavy watering that lush lawns require. While specific temperature data is limited, the coastal location generally keeps conditions humid and favorable for growth.
Sandy Shores Require pH Balancing
The soil pH of 5.37 is significantly more acidic than the ideal 6.0 range, necessitating lime treatments. With a 43.0% sand content, your lawn will drain quickly, so frequent light watering is often better than one heavy soak.

- 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
