Data Story
About Lawn Care in Cape May County, New Jersey
Favorable Conditions at the Cape
Cape May County scores a 54.3 for lawn difficulty, outperforming both the state average of 48.0 and the national median of 50.0. Its Zone 7b classification and coastal moderating effects create a relatively hospitable environment for maintaining a healthy lawn.
Moderate Temperatures and Coastal Rains
With only 21 extreme heat days, the Cape is cooler than much of the state, though precipitation is slightly lower at 43.8 inches. A high growing degree day count of 3,802 means the lawn stays active and requires consistent care for most of the year.
Correcting Well-Drained, Acidic Soil
The soil is well-drained and 66.4% sand, but the pH of 4.01 is significantly lower than the ideal 6.0 range. Extensive soil testing and regular lime applications are necessary to prevent nutrient deficiencies in this highly acidic environment.
Monitoring Dry Coastal Conditions
Cape May saw 26 weeks of drought over the past year, and 100% of the county remains abnormally dry today. Because the soil is so well-drained, lawns can dry out quickly, making supplemental irrigation vital during peak summer weeks.
Perfect Timing for Coastal Lawns
Wait for the last spring frost on April 24 before starting your spring seeding for the best results in Zone 7b. The late first frost on November 9 provides one of the longest fall growing windows in the state to establish strong root systems.

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
- Keep lawn clear of debris
