Yes — Strong Match
epazote is grown as an annual, so season length decides it here, not a winter zone — and New Jersey's typical season runs ~222 frost-free days against the ~60 epazote needs.
Sow by about Sep 15
Epazote is grown as an annual, so what decides it here is season length, not a winter zone. It needs about 60 frost-free days and a typical New Jersey season runs ~222 frost-free days, leaving 162 days of slack. That is room to sow as late as about Sep 15 and still finish before the usual first freeze (Nov 9), or to run a second succession.

Your yard isn't the whole zone.
Epazote is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is. A typical New Jersey site runs ~222 frost-free days, but that is a state median, not your yard: slope, trees, and low spots move the last-frost date across a single parcel.

New Jersey is not one climate
A single New Jersey answer averages 21 counties whose growing seasons are 58 days apart — from 196 frost-free days in Sussex County to 254 in Hudson County. Which end of that your land sits nearer changes what epazote can finish before the first hard freeze.
The middle half of 21 counties runs 215–236 days, with a median of 222 days — a 58-day span end to end.

When to Plant Epazote 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.
Frost hardiness
Epazote takes cold down to about 28°F before a freeze kills it (FAO ECOCROP), so you can plant on the early side of New Jersey's window — even a few weeks before the final hard freeze. That is the point where cold damages growing tissue, not a winter-survival floor — an established perennial comes through far colder while dormant, which is what its hardiness zone tells you.
When to start the seed
Epazote is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — New Jersey's dates above are the whole calendar for it. That makes the last-freeze date the binding constraint, and a warmer pocket of your own yard is worth more to this crop than it is to a transplanted one.
Days to maturity vs. the window
At 55 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 160 days to spare even in New Jersey's tightest freeze scenario — room for a later start or a second sowing.
Timing tuned to sub-state frost dates — Morris County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
Frost-free days
Epazote 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
Epazote needs ~1200 GDD (base 50°F) to ripen. The state median runs ~3340 GDD (from PRISM 1991-2020 climate normals), so New Jersey's typical season clears that easily.
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
Epazote likes near-neutral soil (pH 5.5-8). 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 7.5 — 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. Epazote sits mid-range for drought tolerance, so either extreme can cost you — your soil map unit, not the state average, is the real answer.

Before you plant epazote for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before epazote goes in. What follows is New Jersey’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across New Jersey — and how to grow with it.
We checked the federal record across New Jersey — 41,663 documented sites across 7 of the 9 source types we track.
The most significant on record: 877 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
New Jersey carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

What Else to Consider for Epazote 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 epazote here specifically
Epazote likes pH 5.5–8.0 and its growing tissue burns around 28°F (FAO ECOCROP), yet neither saves it from wet feet — SSURGO maps about 14.3% of New Jersey poorly-drained, where its crown sit and rot.
Set epazote high on bermed, grit-amended ground so winter and storm water drain away from the crown. How to handle it →
What to actually do about these — and the constraints that apply to every New Jersey grower, not just epazote — 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 epazote to your county's window, not the statewide date.
Epazote 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"). Epazote's 60-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Good to Know Before You Plant Epazote
Epazote is listed as toxic to dogs, cats (all) at a moderate level (Cornell). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear. Worth knowing for placement: in New Jersey this is a one-season plant and the first hard freeze (Nov 5 - Nov 17) takes it down, so the exposure above is a summer-long one rather than something standing in the bed all year.
Recommended Epazote Varieties for New Jersey
New Jersey publishes no state variety trial for epazote, so we won't invent a "best for New Jersey" list. Choose types rated to your USDA hardiness zone (6a-8a), and confirm winter survival and drainage against your own parcel.
New Jersey Cooperative Extension
For New Jersey-specific cultivar recommendations, planting calendars, and pest pressure for epazote, the canonical source is Rutgers Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Epazote native to New Jersey?
No — the USDA PLANTS Database lists Epazote 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 Epazote in New Jersey
When can I plant Epazote 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). Epazote takes cold to about 28°F before a freeze kills it (FAO ECOCROP — the point where cold damages growing tissue, not a winter-survival floor), so plant on the early side of that window — even ahead of the final hard freeze.
Can Epazote mature before first frost in New Jersey?
Yes — Epazote matures in 55 days (Growable Ground Plant Database), and New Jersey's dependable hard-freeze-free window runs 215 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 160 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Epazote grown in across New Jersey?
New Jersey spans USDA hardiness zones 6a-8a (USDA ARS PHZM 2023). Epazote carries a range of zones Data pending, 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). Epazote 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 Epazote native to New Jersey?
No — the USDA PLANTS Database lists Epazote 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 Epazote in New Jersey?
Epazote prefers pH 5.5-8 and well (dry spells) drainage (Growable Ground Plant Database). 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.
