Missouri is not one climate
Missouri’s winter-low ladder runs across 115 counties, from zone 5.5 in Atchison County to zone 7.5 in Pemiscot County. That is 20°F between the two counties’ average coldest night — the difference between cranberry overwintering in the ground and coming under cover.
The middle half of 115 counties runs 6–7 zones, with a median of 6.5 zones — a 2-zone span end to end.
Measured across 115 Missouri counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where in Missouri Fits Best
Cranberry is rated for zones 2–7 — a cold floor USDA puts at -50 to -40°F. Against Missouri’s 115 counties that band holds in 110 of them, and the line runs at Atchison County (zone 5b), the coldest county still inside it.

Too little winter chill rather than too much cold — a low-chill selection is what changes it.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.
Even within Missouri's zones 5b-8a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for cranberry (USDA PHZM 2023):

When to Plant Cranberry in Missouri
The frost window
Across Missouri, the last spring hard freeze (28°F) clears between Mar 27 and Apr 2, and the first fall hard freeze lands between Oct 31 and Nov 7 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 212-day window you can count on — up to 225 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
Missouri runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for cranberry, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether cranberry is a permanent planting or a replant-every-spring crop for you turns on your own zone within Missouri; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Crawford County, not the statewide average.
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.
Growing Season Fit
The zone check says cranberry survives winter in part of Missouri, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Cranberry wants 100+ frost-free days; a typical Missouri site sees ~219 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Cranberry needs ~1500 GDD (base 50°F) to ripen. The state median runs ~3770 GDD (from PRISM 1991-2020 climate normals), so Missouri's typical season clears that easily.
Chill hours
Cranberry requires ~1000 chill hours (32-45°F dormancy window). Missouri 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
Cranberry likes near-neutral soil (pH 4.5-6). That's the common-ground band across Missouri's silt loam and clay loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 5 and 5.5 — worth knowing before you decide whether a Missouri soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Missouri 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 31.8% of Missouri as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Cranberry 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.

Before you plant cranberry for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before cranberry goes in. What follows is Missouri’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Missouri — and how to grow with it.
We checked the federal record across Missouri — 33,623 documented sites across 8 of the 9 source types we track.
The most significant on record: 270 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Missouri carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

What an experienced grower watches for around here
In and around Missouri, two things run higher than the national average across Missouri — Mining (4,339 sites) and CAFO (595 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Cranberry in Missouri
Zone compatibility tells you about winter cold survival — but Missouri growers also need to think about:
Highly variable weather with late frosts and early heat
Heavy clay soils in many regions
Ozark soils are thin and rocky
Growing cranberry here specifically
Cranberry roots run shallow and prefer pH 4.5–6.0, but drainage comes first here: SSURGO maps about 31.8% of Missouri as poorly or somewhat-poorly drained, and wet ground rots its crown before pH ever matters.
Plant cranberry on a raised, gravel-amended berm so water drains fast and the crown stays dry. How to handle it →
What to actually do about these — and the constraints that apply to every Missouri grower, not just cranberry — is covered on the Missouri growing guide.
Timing shifts within Missouri
Missouri isn't one climate. In Crawford County, the last hard freeze (28°F) holds until about Apr 10 — roughly 12 days later than the recorded state median — so plant cranberry to your county's window, not the statewide date.
Cranberry needs about 100 days of frost-free season to complete its cycle. Even Crawford County — Missouri’s shortest season at 192 frost-free days — clears that by 92 days, so season length isn’t the constraint anywhere in Missouri. What varies is your own parcel.
Across Missouri’s 115 counties the frost-free season runs from 192 days in Crawford County to 258 days in Pemiscot County — a spread of 66 days, which is why a single statewide planting date misleads. The median Missouri county sees 219 frost-free days, leaving cranberry about 119 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"). Cranberry's 100-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
Cranberry draws honeybees and native bees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, cranberry can only work that bloom inside Missouri's frost window — roughly 219 days, opening after the last 28°F freeze (Mar 27 - Apr 2) and closing at the first (Oct 31 - Nov 7), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Cranberry in Missouri
When can I plant Cranberry in Missouri?
Missouri's last spring hard freeze (28°F) clears between Mar 27 and Apr 2, and the first fall hard freeze lands between Oct 31 and Nov 7 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Cranberry, so this page does not state whether it overwinters in Missouri 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 Cranberry grown in across Missouri?
Missouri spans USDA hardiness zones 5b-8a (USDA ARS PHZM 2023). Cranberry carries a range of zones 2-7, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Missouri site have?
A typical Missouri site sees ~219 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Cranberry needs 100+ 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 Crawford, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Cranberry native to Missouri?
Cranberry is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Missouri. It can still earn a place in a Missouri garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Cranberry in Missouri?
Cranberry prefers pH 4.5-6 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Missouri soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
