About Lawn Care in Gloucester County, New Jersey

A Middle Ground for NJ Lawns

Gloucester County earns a lawn difficulty score of 51.2, sitting just above the national median and the state average. This Zone 7b county offers a relatively balanced environment for homeowners looking to maintain a green yard.

Moderate Heat and Strong Growth

The county sees 20 extreme heat days per year, which is slightly lower than the state average, helping cool-season grasses survive the summer. With 3,696 growing degree days, the climate supports a very active and healthy growing season.

Sandy Soils Need pH Adjustment

Gloucester's soil is 63.9% sand with an acidic pH of 5.25, necessitating amendments to hit the 6.0-7.0 sweet spot. While data on drainage class is limited, the high sand content generally suggests that moisture will move through the soil quickly.

Managing Lawns Through Dry Weeks

With 31 weeks of drought in the last year and 100% of the county currently abnormally dry, water management is a top priority. Using smart irrigation controllers can help maintain lawn health without wasting water in these sandy conditions.

Maximizing the Growing Season

An early final spring frost on April 8 allows for an early start to the seeding season in this 7b zone. Ensure your lawn is established and well-fed before the first fall frost hits on November 1 to guarantee a strong return next year.
