Your yard isn't the whole zone.
Vegetable Amaranth is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is. A typical New York site runs ~185 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. Enter your address and we'll score vegetable amaranth against your land's actual frost dates, sun, and soil.

New York is not one climate
A single New York answer averages 62 counties whose growing seasons are 122 days apart — from 136 frost-free days in Hamilton County to 258 in New York County. Which end of that your land sits nearer changes what vegetable amaranth can finish before the first hard freeze.
The middle half of 62 counties runs 173–204 days, with a median of 184 days — a 122-day span end to end.

When to Plant Vegetable Amaranth in New York
The frost window
Across New York, the last spring hard freeze (28°F) clears between Apr 13 and Apr 29, and the first fall hard freeze lands between Oct 18 and Nov 5 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 172-day window you can count on — up to 206 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 tenderness
Vegetable Amaranth is frost-tender — FAO ECOCROP puts its killing temperature at 32°F — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does. 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
Those dates are when vegetable amaranth goes out, not when it starts. It is sown under cover about 4 weeks ahead, so counting back from New York's late-side last freeze of Apr 29 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Days to maturity vs. the window
At 50 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 122 days to spare even in New York's tightest freeze scenario — room for a later start or a second sowing.
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
The zone check says vegetable amaranth survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Vegetable Amaranth wants 30+ frost-free days; a typical New York site sees ~185 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Vegetable Amaranth needs ~1500 GDD (base 50°F) to ripen. The state median runs ~2042 GDD (from PRISM 1991-2020 climate normals), so New York'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
Vegetable Amaranth tolerates a wide pH range (pH 4.3-8.5) — 4.2 units, acid ground through alkaline — so soil acidity is rarely what limits it in New York. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5.5 and 7.5 — worth knowing before you decide whether a New York soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your New York site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Before you plant vegetable amaranth 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 vegetable amaranth goes in. What follows is New York’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 York — and how to grow with it.
We checked the federal record across New York — 75,562 documented sites across 8 of the 9 source types we track.
The most significant on record: 738 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
New York 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 an experienced grower watches for around here
In and around New York, CAFO runs higher than the national average — 1,029 sites across New York. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.

What Else to Consider for Vegetable Amaranth in New York
Zone compatibility tells you about winter cold survival — but New York growers also need to think about:
Short upstate growing season (100-140 frost-free days in Adirondacks)
Heavy clay soils in western NY require drainage improvement
Late spring frosts through May in higher elevations
Deer browse pressure is heavy in suburban and rural areas
What to actually do about these — and the constraints that apply to every New York grower, not just vegetable amaranth — is covered on the New York growing guide.
Timing shifts within New York
Vegetable Amaranth needs about 30 days of frost-free season to complete its cycle. Even Hamilton County — New York’s shortest season at 136 frost-free days — clears that by 106 days, so season length isn’t the constraint anywhere in New York. What varies is your own parcel.
Across New York’s 62 counties the frost-free season runs from 136 days in Hamilton County to 258 days in New York County — a spread of 122 days, which is why a single statewide planting date misleads. The median New York county sees 185 frost-free days, leaving vegetable amaranth about 155 days of slack on a typical parcel — room for a second sowing where the season runs long.
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"). Vegetable Amaranth's 30-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Common Questions About Growing Vegetable Amaranth in New York
When can I plant Vegetable Amaranth in New York?
New York's last spring hard freeze (28°F) clears between Apr 13 and Apr 29, and the first fall hard freeze lands between Oct 18 and Nov 5 (NOAA Regional Climate Centers ACIS, 1991-2020). Vegetable Amaranth is frost-tender — its killing temperature is 32°F (FAO ECOCROP — the point where cold damages growing tissue, not a winter-survival floor) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
Can Vegetable Amaranth mature before first frost in New York?
Yes — Vegetable Amaranth matures in 50 days (Growable Ground Plant Database), and New York's dependable hard-freeze-free window runs 172 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 122 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 Vegetable Amaranth grown in across New York?
New York spans USDA hardiness zones 4a-7b (USDA ARS PHZM 2023). Vegetable Amaranth carries a range of zones 2-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical New York site have?
A typical New York site sees ~185 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Vegetable Amaranth needs 30+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for Vegetable Amaranth in New York?
Vegetable Amaranth tolerates pH 4.3-8.5 and well (dry spells) drainage (FAO ECOCROP). That is a 4.2-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a New York site — amend for drainage and organic matter first.
