When to Plant Pacific Madrone in Hawaii
The frost window
Hawaii has none — the 1991-2020 station record carries no 28°F killing freeze, so there is no last-frost date to plant after and no first-frost date to harvest before (NOAA Regional Climate Centers ACIS station record). The growing season is year-round; what paces planting here is rainfall, heat and elevation, not the calendar.
Establishment timing
As a long-lived plant, pacific madrone can go in any month here. Aim for the start of your wetter season so it establishes on rainfall rather than on irrigation, and give it a year in the ground before judging it.
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.
Soil + Drainage Fit
Pacific Madrone likes near-neutral soil (pH 4.5-7.4). That's the common-ground band across Hawaii's volcanic and laterite — a soil test confirms it for your site.

What Else to Consider for Pacific Madrone in Hawaii
Zone compatibility tells you about winter cold survival — but Hawaii growers also need to think about:
Extreme rainfall variation — desert on one side, rainforest on the other
Volcanic soil is nutrient-poor in young flows
Invasive species pressure is severe
What to actually do about these — and the constraints that apply to every Hawaii grower, not just pacific madrone — is covered on the Hawaii growing guide.
Where in Hawaii Pacific Madrone Is Zone-Hardy
Pacific Madrone is rated for USDA zones 9–13. Every one of Hawaii’s 5 counties sits inside that band — from Hawaii County at zone 10a-11b to Maui County at zone 10a-11b — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.
Across those 5 counties Hawaii’s winter-low ladder runs from zone 10a-11b in Hawaii County to zone 10a-11b in Maui 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.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Pacific Madrone’s zone 9–13 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Pollinator + Wildlife Value
Pacific Madrone draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Pacific Madrone's flowers are not fenced in by a freeze date here: the 1991-2020 record resolves no 28°F killing frost anywhere in Hawaii, so what limits bloom is the plant's own cycle rather than the calendar.
Hawaii Cooperative Extension
For Hawaii-specific cultivar recommendations, planting calendars, and pest pressure for pacific madrone, the canonical source is UH Mānoa CTAHR Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Pacific Madrone native to Hawaii?
Pacific Madrone is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Hawaii. It can still earn a place in a Hawaii garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Pacific Madrone in Hawaii
When can I plant Pacific Madrone in Hawaii?
Any month — Hawaii records no 28°F killing freeze in the 1991-2020 station record, so there is no last-frost date to wait for and the growing season is year-round (NOAA Regional Climate Centers ACIS station record). Pace planting by rainfall, heat and elevation instead: the summit country does freeze, and no station up there carries a long enough record to date it.
What hardiness zone is Pacific Madrone grown in across Hawaii?
Hawaii spans USDA hardiness zones 8b-13a (USDA ARS PHZM 2023). Pacific Madrone carries a range of zones 9-13, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Hawaii site have?
A typical Hawaii site sees ~365 frost-free days per year (derived from NOAA Regional Climate Centers ACIS station record, 1991-2020). Pacific Madrone 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 Pacific Madrone native to Hawaii?
Pacific Madrone is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Hawaii. It can still earn a place in a Hawaii garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Pacific Madrone in Hawaii?
Pacific Madrone prefers pH 4.5-7.4 (USDA PLANTS). That sits in the common-ground band across Hawaii soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Pacific Madrone actually grow on my specific land in Hawaii?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores pacific madrone against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
