Unlikely — Zone Mismatch
nutmeg (zones 11-12) does not overlap with Louisiana's zone range (8b-10b). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Nutmeg is hardy to zone 11, and the warmest ground in Louisiana is zone 10 — 1 zone short. Planted in open ground it will not survive a Louisiana winter. To grow it here, grow nutmeg in a hoop house or unheated greenhouse — its modeled 1.5-zone lift covers this gap.

Louisiana is not one climate
Louisiana’s winter-low ladder runs across 64 counties, from zone 8.5 in Bienville County to zone 10 in Plaquemines County. That is 15°F between the two counties’ average coldest night — the difference between nutmeg overwintering in the ground and coming under cover.
The middle half of 64 counties runs 8.5–9 zones, with a median of 9 zones — a 1.5-zone span end to end.
Measured across 64 Louisiana counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where Nutmeg Stands in Louisiana
Nutmeg is rated for zones 11–12 — a cold floor USDA puts at 40 to 50°F. No Louisiana county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about Louisiana winters, not about nutmeg.

When to Plant Nutmeg in Louisiana
The frost window
Across Louisiana, the last spring hard freeze (28°F) clears between Jan 30 and Feb 17, and the first fall hard freeze lands between Nov 30 and Dec 8 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 286-day window you can count on — up to 312 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
Louisiana runs as cold as USDA zone 8, and no sourced winter-hardiness floor is on record for nutmeg, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether nutmeg is a permanent planting or a replant-every-spring crop for you turns on your own zone within Louisiana; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Claiborne 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
The zone check says nutmeg does not survive a Louisiana 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 Louisiana under protection.
Frost-free days
Nutmeg wants 365+ frost-free days; a typical Louisiana site sees ~298 (NOAA Regional Climate Centers ACIS, 1991-2020) — 67 days short of what it needs. A typical Louisiana season does not carry this crop to harvest outdoors, and a gap that size is not one an earlier sowing date or a faster cultivar closes; growing it here means growing it under cover.
Growing degree days
Nutmeg needs ~5500 GDD (base 50°F) to ripen. The state median runs ~6204 GDD (from PRISM 1991-2020 climate normals), so Louisiana sits right at the threshold — pay attention to siting and microclimate.
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
Nutmeg likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across Louisiana's alluvial clay and muck — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 7 — worth knowing before you decide whether a Louisiana soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Louisiana 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 45.5% of Louisiana as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Nutmeg 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.

Before you plant nutmeg 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 nutmeg goes in. What follows is Louisiana’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 Louisiana — and how to grow with it.
We checked the federal record across Louisiana — 47,113 documented sites across 7 of the 9 source types we track.
The most significant on record: 168 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Louisiana 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 Nutmeg in Louisiana
Zone compatibility tells you about winter cold survival — but Louisiana growers also need to think about:
Extreme humidity and rainfall promote rot and fungal diseases
Poor drainage in delta and coastal areas
Hurricane damage risk from June through November
Growing nutmeg here specifically
Nutmeg rates to USDA zones 11–12 and takes frost damage on growing tissue around 32°F (FAO ECOCROP), but cold isn't the risk in Louisiana — wet is: with roughly 45.5% of its soils poorly-drained (SSURGO), soggy ground rots the crown.
Give nutmeg a raised bed or mounded row with coarse amendment so its crown never sit wet. How to handle it →
What to actually do about these — and the constraints that apply to every Louisiana grower, not just nutmeg — is covered on the Louisiana growing guide.
Timing shifts within Louisiana
Louisiana isn't one climate. In Claiborne County, the last hard freeze (28°F) holds until about Mar 2 — roughly 19 days later than the recorded state median — so plant nutmeg to your county's window, not the statewide date.
Nutmeg needs about 365 days of frost-free season to complete its cycle. 1 of Louisiana’s 64 counties give it that outright. The tightest that does is Plaquemines County at 365 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Louisiana’s 64 counties the frost-free season runs from 265 days in Claiborne County to 365 days in Plaquemines County — a spread of 100 days, which is why a single statewide planting date misleads. The median Louisiana county sees 298 frost-free days, which is 67 days short of what nutmeg needs — so on a typical Louisiana parcel this is a transplant-or-protect crop, not a direct-sow one.
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"). Nutmeg's 365-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
Nutmeg draws native bees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, nutmeg can only work that bloom inside Louisiana's frost window — roughly 298 days, opening after the last 28°F freeze (Jan 30 - Feb 17) and closing at the first (Nov 30 - Dec 8), per NOAA Regional Climate Centers ACIS, 1991-2020.
Good to Know Before You Plant Nutmeg
Nutmeg is listed as toxic to dogs, cats (seeds) at a moderate level (ASPCA). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear.
Recommended Nutmeg Varieties for Louisiana
Louisiana publishes no state variety trial for nutmeg, so we won't invent a "best for Louisiana" list. Choose types rated to your USDA hardiness zone (8b-10b), and confirm winter survival and drainage against your own parcel.

Common Questions About Growing Nutmeg in Louisiana
When can I plant Nutmeg in Louisiana?
Louisiana's last spring hard freeze (28°F) clears between Jan 30 and Feb 17, and the first fall hard freeze lands between Nov 30 and Dec 8 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Nutmeg, so this page does not state whether it overwinters in Louisiana 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 Nutmeg grown in across Louisiana?
Louisiana spans USDA hardiness zones 8b-10b (USDA ARS PHZM 2023). Nutmeg carries a range of zones 11-12, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Louisiana site have?
A typical Louisiana site sees ~298 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Nutmeg needs 365+ 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 Claiborne, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for Nutmeg in Louisiana?
Nutmeg prefers pH 5.5-7.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Louisiana soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Nutmeg actually grow on my specific land in Louisiana?
