South Jersey’s planting zones range from 7a to 8a, which means that the lowest annual temperatures are between 0 to 15 degrees Fahrenheit. Much of south Jersey in planting zone 7a, but the west and the coast are warmer.
Knowing your planting zone, also known as a hardiness zone, is essential to seeding grasses and plants that will thrive here in south Jersey. Plus, different areas require varying levels of care. Here’s all about south Jersey’s planting zones.
Hardiness zone 7a: Southeast Jersey
In south Jersey’s hardiness zone 7a, temperatures don’t go down below 0 to 5 degrees Fahrenheit. It’s found in much of the state, including:

Hardiness zone 7b: West Jersey and the coast
In hardiness zone 7b, temperatures rarely drop below 5 to 10 degrees Fahrenheit. This climate is most common in coastal areas. It’s also more prevalent in the western parts of South Jersey. Here are a few examples of where you can find hardiness zone 7b:

| Gloucester | Most of the county, except the very eastern border and a small part of the west | Woodbury, Swedesboro, Glassboro |
| Salem | Almost everywhere, except a small part at the eastern border | Woodstown, Alloway, most of Pittsgrove |
Again, it’s debatable whether Ocean and Monmouth count as southern or central new Jersey. But these two counties also have a hardiness zone of 7b in some places:
| County | Where | Examples of cities or towns |
| Monmouth | The east coast | Long Branch, Asbury Park |
| Ocean | The east coast | Stafford Township, Long Beach |
Hardiness zone 8a: The southeast coast
