Unlikely — Zone Mismatch
tangerine (zones 9-11) does not overlap with New Jersey's zone range (6a-8a). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Tangerine is hardy to zone 9, and the warmest ground in New Jersey is zone 8 — 1 zone short. Planted in open ground it will not survive a New Jersey winter. To grow it here, grow tangerine in a container and move it under cover for the coldest weeks, or give it a greenhouse.
Season extension and overwintering under cover both work at this margin. How to buy the weeks →

When to Plant Tangerine in New Jersey
The frost window
Across New Jersey, the last spring hard freeze (28°F) clears between Mar 26 and Apr 4, and the first fall hard freeze lands between Nov 5 and Nov 17 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 215-day window you can count on — up to 236 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
New Jersey runs as cold as USDA zone 6, and no sourced winter-hardiness floor is on record for tangerine, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether tangerine is a permanent planting or a replant-every-spring crop for you turns on your own zone within New Jersey; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Morris County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says tangerine does not survive a New Jersey winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on New Jersey under protection.
Frost-free days
Tangerine wants 60+ frost-free days; a typical New Jersey site sees ~222 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Tangerine needs ~3500 GDD (base 50°F) to ripen. The state median runs ~3340 GDD (from PRISM 1991-2020 climate normals), so New Jersey's typical season runs short on heat — pick a south-facing site and consider season extension.
Chill hours
Tangerine has no winter-chill requirement — its listed minimum is 0 hours (USDA PLANTS Database). New Jersey typically banks ~2500 chill hours per winter (from PRISM 1991-2020 climate normals), so chill is not a constraint on this plant here — and not evidence in its favour either. Winter survival and season length are what decide it.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Tangerine likes near-neutral soil (pH 5.5-8.3). That's the common-ground band across New Jersey's sandy loam (pine barrens) and silt loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 6.8 — worth knowing before you decide whether a New Jersey soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your New Jersey site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 14.3% of New Jersey as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Tangerine has low drought tolerance, so it is the fast-draining end that will cost you — your soil map unit, not the state average, is the real answer.

What Else to Consider for Tangerine in New Jersey
Zone compatibility tells you about winter cold survival — but New Jersey growers also need to think about:
Sandy Pine Barrens soils are nutrient-poor
Urban heat island effects in northern NJ
Deer browse is extreme in suburban areas
Growing tangerine here specifically
Tangerine roots run deep and prefer pH 5.5–8.3, but drainage comes first here: SSURGO maps about 14.3% of New Jersey as poorly or somewhat-poorly drained, and wet ground rots its crown before pH ever matters.
Plant tangerine on a raised, gravel-amended berm so water drains fast and the crown stays dry. How to handle it →
What to actually do about these — and the constraints that apply to every New Jersey grower, not just tangerine — is covered on the New Jersey growing guide.
Timing shifts within New Jersey
New Jersey isn't one climate. In Morris County, the last hard freeze (28°F) holds until about Apr 11 — roughly 11 days later than the recorded state median — so plant tangerine to your county's window, not the statewide date.
Tangerine needs about 60 days of frost-free season to complete its cycle. Even Sussex County — New Jersey’s shortest season at 196 frost-free days — clears that by 136 days, so season length isn’t the constraint anywhere in New Jersey. What varies is your own parcel.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Tangerine's 60-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Tangerine draws honeybees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, tangerine can only work that bloom inside New Jersey's frost window — roughly 222 days, opening after the last 28°F freeze (Mar 26 - Apr 4) and closing at the first (Nov 5 - Nov 17), per NOAA Regional Climate Centers ACIS, 1991-2020.
Good to Know Before You Plant Tangerine
Tangerine is listed as toxic to dogs, cats (leaves, stems, peel) at a mild level (ASPCA). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear.
New Jersey Cooperative Extension
For New Jersey-specific cultivar recommendations, planting calendars, and pest pressure for tangerine, the canonical source is Rutgers Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Tangerine native to New Jersey?
No — the USDA PLANTS Database lists Tangerine as introduced rather than native in the Lower 48, so it is not part of New Jersey's native flora. It grows here as a garden plant; pairing it with a few New Jersey natives keeps local pollinators fed too.

Common Questions About Growing Tangerine in New Jersey
When can I plant Tangerine in New Jersey?
New Jersey's last spring hard freeze (28°F) clears between Mar 26 and Apr 4, and the first fall hard freeze lands between Nov 5 and Nov 17 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Tangerine, so this page does not state whether it overwinters in New Jersey and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Tangerine grown in across New Jersey?
New Jersey spans USDA hardiness zones 6a-8a (USDA ARS PHZM 2023). Tangerine carries a range of zones 9-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical New Jersey site have?
A typical New Jersey site sees ~222 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Tangerine needs 60+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Morris, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Tangerine native to New Jersey?
No — the USDA PLANTS Database lists Tangerine as introduced rather than native in the Lower 48, so it is not part of New Jersey's native flora. It grows here as a garden plant; pairing it with a few New Jersey natives keeps local pollinators fed too.
How should I amend the soil for Tangerine in New Jersey?
Tangerine prefers pH 5.5-8.3 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across New Jersey soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
