New Jersey Planting Zones



New Jersey is divided into four distinct planting zones according to the USDA Plant Hardiness Zone Map: 6b, 7a, 7b, and 8a.


  • Zone 6b: This zone experiences minimum temperatures ranging from -5°F to 0°F and is primarily located in the northern parts of the state, including Sussex County, Warren, and Morris counties.

  • Zone 7a: With minimum temperatures between 0°F and 5°F, this zone covers much of central New Jersey and parts of northern New Jersey, including Essex and Morris counties.

  • Zone 7b: This zone has minimum temperatures from 5°F to 10°F and is located in areas like eastern Bergen and Essex counties, as well as parts of southern New Jersey.

  • Zone 8a: The warmest zone in New Jersey, with minimum temperatures ranging from 10°F to 15°F, is found primarily in the southernmost areas, including Cape May and parts of Atlantic City.

These zones reflect the average annual extreme minimum temperatures and have shifted slightly due to climate change, allowing for a broader range of plants to thrive in the state. Learn more about New Jersey planting zone and enhance your landscape.
