Unlikely — Zone Mismatch
mangosteen (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
Mangosteen 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 mangosteen in a container and move it under cover for the coldest weeks, or give it a greenhouse.

When to Plant Mangosteen 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 mangosteen, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether mangosteen 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: 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 mangosteen 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
Mangosteen 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
Mangosteen needs ~6000 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.
Chill hours
Mangosteen has no winter-chill requirement — its listed minimum is 0 hours (USDA PLANTS Database). Louisiana typically banks ~641 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
Mangosteen tolerates a wide pH range (pH 4.3-7.5) — 3.2 units, acid ground through alkaline — so soil acidity is rarely what limits it in Louisiana. 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 and 6 — 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. Mangosteen 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.

Mangosteen in Louisiana — Quick Answer
- Verdict: Unlikely — Zone Mismatch
- Plant Zones: 11-12 (USDA PLANTS Database)
- State Zones: 8b-10b (USDA ARS PHZM 2023)

What Else to Consider for Mangosteen 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 mangosteen here specifically
Mangosteen needs sharp drainage and sends deep roots hardy to about 59°F; in Louisiana, about 45.5% of soils are poorly-drained (SSURGO), and standing water is what actually kills it.
Build mangosteen up on a coarse, free-draining mound so its crown never sit in saturated soil. How to handle it →
What to actually do about these — and the constraints that apply to every Louisiana grower, not just mangosteen — 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 mangosteen to your county's window, not the statewide date.
Mangosteen 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 mangosteen 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"). Mangosteen'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
Mangosteen draws honeybees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, mangosteen 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.
Louisiana Cooperative Extension
For Louisiana-specific cultivar recommendations, planting calendars, and pest pressure for mangosteen, the canonical source is LSU AgCenter. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Mangosteen native to Louisiana?
No — the USDA PLANTS Database lists Mangosteen as introduced rather than native in the Lower 48, so it is not part of Louisiana's native flora. It grows here as a garden plant; pairing it with a few Louisiana natives keeps local pollinators fed too.

Common Questions About Growing Mangosteen in Louisiana
When can I plant Mangosteen 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 Mangosteen, 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 Mangosteen grown in across Louisiana?
Louisiana spans USDA hardiness zones 8b-10b (USDA ARS PHZM 2023). Mangosteen 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). Mangosteen 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.
Is Mangosteen native to Louisiana?
No — the USDA PLANTS Database lists Mangosteen as introduced rather than native in the Lower 48, so it is not part of Louisiana's native flora. It grows here as a garden plant; pairing it with a few Louisiana natives keeps local pollinators fed too.
How should I amend the soil for Mangosteen in Louisiana?
Mangosteen tolerates pH 4.3-7.5 and well (dry spells) drainage (FAO ECOCROP). That is a 3.2-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Louisiana site — amend for drainage and organic matter first.
