Kansas is not one climate
Kansas’s winter-low ladder runs across 105 counties, from zone 6 in Atchison County to zone 7 in Wilson County. That is 10°F between the two counties’ average coldest night — the difference between muscadine grape overwintering in the ground and coming under cover.
The middle half of 105 counties runs 6–6.5 zones, with a median of 6.5 zones — a 1-zone span end to end.
Measured across 105 Kansas 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 Kansas Fits Best
Muscadine Grape is rated for zones 7–9 — a cold floor USDA puts at 0 to 10°F. Against Kansas’s 105 counties that band holds in 16 of them, and the line runs at Barber County (zone 7a), the coldest county still inside 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 Kansas's zones 5b-7a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for muscadine grape (USDA PHZM 2023):

When to Plant Muscadine Grape in Kansas
The frost window
Across Kansas, the last spring hard freeze (28°F) clears between Apr 1 and Apr 12, and the first fall hard freeze lands between Oct 25 and Nov 3 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 196-day window you can count on — up to 216 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
Kansas runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for muscadine grape, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether muscadine grape is a permanent planting or a replant-every-spring crop for you turns on your own zone within Kansas; check its hardiness range against that before treating it as long-lived ground.
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 muscadine grape survives winter in part of Kansas, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Muscadine Grape wants 150+ frost-free days; a typical Kansas site sees ~208 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
Growing degree days
Muscadine Grape needs ~3000 GDD (base 50°F) to ripen. The state median runs ~3821 GDD (from PRISM 1991-2020 climate normals), so Kansas's typical season clears that easily.
Chill hours
Muscadine Grape requires ~600 chill hours (32-45°F dormancy window). Kansas 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
Muscadine Grape likes near-neutral soil (pH 5.8-8). That's the common-ground band across Kansas's prairie loam and silt loam — 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 Kansas soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Kansas site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Before you plant muscadine grape 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 muscadine grape goes in. What follows is Kansas’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 Kansas — and how to grow with it.
We checked the federal record across Kansas — 33,298 documented sites across 8 of the 9 source types we track.
The most significant on record: 146 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Kansas 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 Kansas, two things run higher than the national average across Kansas — Nitrate (15,878 sites) and CAFO (485 sites). That's not a problem with your land — it's information about it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).
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 Muscadine Grape in Kansas
Zone compatibility tells you about winter cold survival — but Kansas growers also need to think about:
Low rainfall in western KS requires irrigation
Extreme wind and hail during severe storm season
Hot dry summers with 100F+ days
What to actually do about these — and the constraints that apply to every Kansas grower, not just muscadine grape — is covered on the Kansas growing guide.
Timing shifts within Kansas
Muscadine Grape needs about 150 days of frost-free season to complete its cycle. Even Greeley County — Kansas’s shortest season at 177 frost-free days — clears that by 27 days, so season length isn’t the constraint anywhere in Kansas. What varies is your own parcel.
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"). Muscadine Grape's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

What pests threaten muscadine grape in Kansas?
Japanese beetle is documented in Kansas and will find muscadine grape, but it is manageable here. What an experienced grower watches for, and does:
Japanese beetle
Worth watchingThis is on the University of Minnesota's list of Japanese beetle preferred plants — but their read is that fruits, vegetables and herbs tolerate limited leaf feeding, and that in most cases the damage is cosmetic and will not kill the plant.
What to do: Protect it only through the few peak weeks: handpick into soapy water in the cool of morning, harvest regularly through July and August to take the feeding pressure off the edible parts, and keep the plant well watered — a vigorous plant outgrows feeding that looks worse than it is. Do not hang a beetle trap.

Common Questions About Growing Muscadine Grape in Kansas
When can I plant Muscadine Grape in Kansas?
Kansas's last spring hard freeze (28°F) clears between Apr 1 and Apr 12, and the first fall hard freeze lands between Oct 25 and Nov 3 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Muscadine Grape, so this page does not state whether it overwinters in Kansas 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 Muscadine Grape grown in across Kansas?
Kansas spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Muscadine Grape 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 Kansas site have?
A typical Kansas site sees ~208 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Muscadine Grape needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Muscadine Grape native to Kansas?
Muscadine Grape is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Kansas. It can still earn a place in a Kansas garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Muscadine Grape in Kansas?
Muscadine Grape prefers pH 5.8-8 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Kansas soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
