Unlikely — Zone Mismatch
kiwi (zones 7-9) does not overlap with North Dakota's zone range (3b-4b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Kiwi is hardy to zone 7, and the warmest ground in North Dakota is zone 5 — 2 zones short. Planted in open ground it will not survive a North Dakota winter. To grow it here, grow kiwi under glass — a greenhouse is the only lift this wide the engine models.

When to Plant Kiwi in North Dakota
The frost window
Across North Dakota, the last spring hard freeze (28°F) clears between Apr 30 and May 6, and the first fall hard freeze lands between Oct 4 and Oct 9 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 151-day window you can count on — up to 162 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
North Dakota runs as cold as USDA zone 3, and no sourced winter-hardiness floor is on record for kiwi, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether kiwi is a permanent planting or a replant-every-spring crop for you turns on your own zone within North Dakota; 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 kiwi does not survive a North Dakota 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 North Dakota under protection.
Frost-free days
Kiwi wants 210+ frost-free days; a typical North Dakota site sees ~157 (NOAA Regional Climate Centers ACIS, 1991-2020) — 53 days short of what it needs. A typical North Dakota 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
Kiwi needs ~3000 GDD (base 50°F) to ripen. The state median runs ~1913 GDD (from PRISM 1991-2020 climate normals), so North Dakota's typical season runs short on heat — pick a south-facing site and consider season extension.
Chill hours
Kiwi requires ~400 chill hours (32-45°F dormancy window). North Dakota typically banks ~2500 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
Kiwi likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across North Dakota's prairie loam and clay (red river valley) — 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 North Dakota soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your North Dakota 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 20.3% of North Dakota as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Kiwi 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.

What Else to Consider for Kiwi in North Dakota
Zone compatibility tells you about winter cold survival — but North Dakota growers also need to think about:
Extreme cold (-40F) and short growing season
Persistent wind desiccates plants
Low rainfall in western ND
Growing kiwi here specifically
Kiwi needs sharp drainage and sends deep roots hardy to about 46°F; in North Dakota, about 20.3% of soils are poorly-drained (SSURGO), and standing water is what actually kills it.
Build kiwi 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 North Dakota grower, not just kiwi — is covered on the North Dakota growing guide.
Timing shifts within North Dakota
Kiwi needs about 210 days of frost-free season to complete its cycle. No North Dakota county gives it that outdoors: even Richland County, the state’s longest season at 170 frost-free days, falls 40 days short — so it needs transplants, a short-season variety, or covered growing.
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"). Kiwi's 210-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
Kiwi draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, kiwi can only work that bloom inside North Dakota's frost window — roughly 157 days, opening after the last 28°F freeze (Apr 30 - May 6) and closing at the first (Oct 4 - Oct 9), per NOAA Regional Climate Centers ACIS, 1991-2020.
North Dakota Cooperative Extension

Is Kiwi native to North Dakota?
No — the USDA PLANTS Database lists Kiwi as introduced rather than native in the Lower 48, so it is not part of North Dakota's native flora. It grows here as a garden plant; pairing it with a few North Dakota natives keeps local pollinators fed too.

Common Questions About Growing Kiwi in North Dakota
When can I plant Kiwi in North Dakota?
North Dakota's last spring hard freeze (28°F) clears between Apr 30 and May 6, and the first fall hard freeze lands between Oct 4 and Oct 9 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Kiwi, so this page does not state whether it overwinters in North Dakota 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 Kiwi grown in across North Dakota?
North Dakota spans USDA hardiness zones 3b-4b (USDA ARS PHZM 2023). Kiwi carries a range of zones 7-9, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical North Dakota site have?
A typical North Dakota site sees ~157 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Kiwi needs 210+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Kiwi native to North Dakota?
No — the USDA PLANTS Database lists Kiwi as introduced rather than native in the Lower 48, so it is not part of North Dakota's native flora. It grows here as a garden plant; pairing it with a few North Dakota natives keeps local pollinators fed too.
How should I amend the soil for Kiwi in North Dakota?
Kiwi prefers pH 5.5-7.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across North Dakota soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
