Kent County: Maryland's Top Lawn Performer
Kent County is a top performer for Maryland lawns with a difficulty score of 57.6, the highest among its neighbors. Its 7b hardiness zone provides a balanced environment that is much easier to manage than the state average.
Rapid Growth Despite High Summer Heat
The area receives 46 inches of precipitation annually but endures 37 extreme heat days, which is 10 days more than the state average. With 3,938 growing degree days, the grass grows quickly and requires a dedicated mowing schedule to stay neat.
Managing Fast-Draining Fine Sandy Loam
The soil is well-drained fine sandy loam, though the pH of 5.17 is lower than the ideal 6.0 range. With 40.8% sand content, these lawns drain quickly, which is great for root health but may require more frequent light watering during heatwaves.
Staying Green Through Dry Coastal Weather
Kent County has been relatively resilient, with only 12 weeks in drought over the past year. While 71.4% of the area is currently abnormally dry, the county remains in better shape than many other parts of Maryland.
Maximize Your Long Coastal Growing Season
Tall fescue and hybrid bermudagrass flourish in this well-drained, sandy soil. For best results, seed your lawn after the April 3 frost but before the November 5 fall frost to take full advantage of the long growing window.
