Generally — Most Areas
goji berry (zones 4-9) suits most of Louisiana (8b-10b) — zones 8-9 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Louisiana spans zones 8b-10b, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score goji berry against your parcel's actual hardiness, soil, and sun.

When to Plant Goji Berry 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 goji berry, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether goji berry 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.
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 goji berry survives winter in part of Louisiana, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Days to maturity
Goji Berry matures in ~730 days (Growable Ground Plant Database). A typical Louisiana site has ~298 frost-free days, so tight — start indoors or use season-extension to close the gap.
Growing degree days
Goji Berry needs ~1800 GDD (base 50°F) to ripen. The state median runs ~6204 GDD (from PRISM 1991-2020 climate normals), so Louisiana's typical season clears that easily.
Chill hours
Goji Berry requires ~200 chill hours (32-45°F dormancy window). Louisiana typically banks ~641 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
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
Goji Berry likes near-neutral soil (pH 6.5-8.1). 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 6.8 and 7.2 — 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.

What Else to Consider for Goji Berry 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
What to actually do about these — and the constraints that apply to every Louisiana grower, not just goji berry — is covered on the Louisiana growing guide.
Where in Louisiana Goji Berry Is Zone-Hardy
Goji Berry is rated for USDA zones 4–9. 51 of Louisiana’s 64 counties fall inside that band. The coldest that does is Bienville County at zone 8b. 13 counties sit above its zone 9 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Louisiana decides this one.
Across those 64 counties Louisiana’s winter-low ladder runs from zone 8b in Bienville County to zone 10a in Plaquemines County — 1.5 USDA zones of spread, which is 15°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Claiborne County holds its last hard freeze (28°F) until about Mar 2, while St. Bernard County is clear by Jan 16 — 45 days apart. Set goji berry out on your county’s date, not the state’s.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost".

Where in Louisiana Fits Best
Even within Louisiana's zones 8b-10b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for goji berry (USDA PHZM 2023):
Louisiana Cooperative Extension
For Louisiana-specific cultivar recommendations, planting calendars, and pest pressure for goji berry, the canonical source is LSU AgCenter. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Goji Berry native to Louisiana?
No — the USDA PLANTS Database lists Goji Berry 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 Goji Berry in Louisiana
When can I plant Goji Berry 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 Goji Berry, 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 Goji Berry grown in across Louisiana?
Louisiana spans USDA hardiness zones 8b-10b (USDA ARS PHZM 2023). Goji Berry carries a range of zones 4-9, 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). Goji Berry should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Goji Berry native to Louisiana?
No — the USDA PLANTS Database lists Goji Berry 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 Goji Berry in Louisiana?
Goji Berry prefers pH 6.5-8.1 and well (dry spells) drainage (Growable Ground Plant Database). 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.
