Frost dates, planting zones, soil types, and what actually thrives in New Jersey — from mountains to coast.
Frost dates & zones
New Jersey spans USDA zones 6a (northwest NJ / Highlands) to 7b (Cape May / Atlantic coast). Verify your exact zone and frost dates with your county Extension office — elevation and microclimates create real variation.

Pine Barrens sandy soils need lime, compost, and fertilizer — naturally very acidic. Northwest Highlands soils also acidic. Delaware valley alluvial soils are productive. Rutgers Extension county offices provide soil testing.
Know your soil
NJ soils vary significantly. The Pine Barrens — covering much of south-central NJ — have extremely sandy, acidic, nutrient-poor soils that drain instantly. The Coastal Plain has loamy sandy soils. The northwest Highlands have rocky, acidic forest soils. The Delaware River valley has productive alluvial soils. Many suburban and urban soils are heavily disturbed.
