Generally — Most Areas
kauri (zones 10-12) suits most of Florida (8b-12a) — zones 10-12 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Florida spans zones 8b-12a, 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 kauri against your parcel's actual hardiness, soil, and sun.

When to Plant Kauri in Florida
The frost window
Across Florida, the last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 300-day window you can count on — up to 327 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
Florida runs as cold as USDA zone 8, and no sourced winter-hardiness floor is on record for kauri, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether kauri is a permanent planting or a replant-every-spring crop for you turns on your own zone within Florida; 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 kauri survives winter in part of Florida, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Kauri wants 300+ frost-free days; a typical Florida site sees ~320 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
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
Kauri likes near-neutral soil (pH 4-6.5). That's the common-ground band across Florida's sandy and muck (everglades) — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 4.5 and 6 — worth knowing before you decide whether a Florida soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Florida site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Kauri in Florida — Quick Answer
- Verdict: Generally — Most Areas
- Plant Zones: 10-12 (USDA PLANTS Database)
- State Zones: 8b-12a (USDA ARS PHZM 2023)
- Growing Season: 28°F hard freezes about Jan 25 - Feb 10 to Dec 7 - Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020)
What Else to Consider for Kauri in Florida
Zone compatibility tells you about winter cold survival — but Florida growers also need to think about:
Sandy soils drain too fast and hold few nutrients — frequent fertilization needed
Humidity drives fungal diseases (powdery mildew, black spot, rust)
Hurricane season (June-November) can destroy plantings
Nematodes are a serious pest in sandy FL soils
What to actually do about these — and the constraints that apply to every Florida grower, not just kauri — is covered on the Florida growing guide.
Timing shifts within Florida
Kauri needs about 300 days of frost-free season to complete its cycle. 51 of Florida’s 67 counties give it that outright. The tightest that does is Clay County at 300 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Florida’s 67 counties the frost-free season runs from 281 days in Holmes County to 365 days in Sarasota County — a spread of 84 days, which is why a single statewide planting date misleads. The median Florida county sees 320 frost-free days, leaving kauri about 20 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"). Kauri's 300-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Florida Fits Best

Common Questions About Growing Kauri in Florida
When can I plant Kauri in Florida?
Florida's last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Kauri, so this page does not state whether it overwinters in Florida 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 Kauri grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Kauri carries a range of zones 10-12, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Florida site have?
A typical Florida site sees ~320 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Kauri needs 300+ 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 Kauri in Florida?
Kauri prefers pH 4-6.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Florida soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Kauri actually grow on my specific land in Florida?
