New Jersey Frost Dates
New Jersey offers a moderate to fairly long growing season, helped in many places by coastal influence and a generally humid climate. South Jersey often warms sooner than the north, while inland valleys and higher northwestern ground can hold spring frost later than shoreline gardens.
