Unlikely — Zone Mismatch
pomelo (zones 9-11) does not overlap with Kansas's zone range (5b-7a). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Pomelo is hardy to zone 9, and the warmest ground in Kansas is zone 7 — 2 zones short. Planted in open ground it will not survive a Kansas winter. To grow it here, grow pomelo under glass — a greenhouse is the only lift this wide the engine models.

When to Plant Pomelo 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 pomelo, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether pomelo 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.
Timing tuned to sub-state frost dates — Greeley County, not the statewide average.
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.
Soil + Drainage Fit
Pomelo tolerates a wide pH range (pH 4.5-8) — 3.5 units, acid ground through alkaline — so soil acidity is rarely what limits it in Kansas. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5.5 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.
Your land, not the state average
Kansas's soils run mostly silt loam, but SSURGO maps the series, texture, and drainage under your exact parcel. Pomelo needs about 59 inches of workable depth, so it is that horizon — not the surface — you are testing for. That map unit, not the state average, decides how pomelo performs.

Pomelo in Kansas — Quick Answer
- Verdict: Unlikely — Zone Mismatch
- Plant Zones: 9-11 (USDA PLANTS Database)
- State Zones: 5b-7a (USDA ARS PHZM 2023)
- Growing Season: 28°F hard freezes about Apr 1 - Apr 12 to Oct 25 - Nov 3 (NOAA Regional Climate Centers ACIS, 1991-2020)
What Else to Consider for Pomelo 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
Growing pomelo here specifically
Pomelo prefers pH 4.5–8.0 and room to root deep; across much of Kansas, restrictive group-D subsoil (SSURGO) blocks that depth.
Build pomelo a deep raised bed of loose soil to bypass the dense subsoil entirely. How to handle it →
What to actually do about these — and the constraints that apply to every Kansas grower, not just pomelo — is covered on the Kansas growing guide.
Timing shifts within Kansas
Kansas isn't one climate. In Greeley County, the last hard freeze (28°F) holds until about Apr 23 — roughly 18 days later than the recorded state median — so plant pomelo to your county's window, not the statewide date.
County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Where in Kansas Pomelo Is Zone-Hardy
Pomelo is rated for USDA zones 9–11. No Kansas county reaches it. Even Wilson County, the state’s mildest winter at zone 7a, sits below the plant’s zone 9 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
Across those 105 counties Kansas’s winter-low ladder runs from zone 6a in Atchison County to zone 7a in Wilson County — 1 USDA zone of spread, which is 10°F between the two counties’ average coldest night of the year. None of that range reaches the band pomelo needs, so here the statewide answer really is the answer.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Pomelo’s zone 9–11 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
Pomelo draws honeybees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, pomelo can only work that bloom inside Kansas's frost window — roughly 208 days, opening after the last 28°F freeze (Apr 1 - Apr 12) and closing at the first (Oct 25 - Nov 3), per NOAA Regional Climate Centers ACIS, 1991-2020.
Good to Know Before You Plant Pomelo
Pomelo is listed as toxic to dogs, cats (leaves, stems, peel) at a mild level (ASPCA). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear.
Kansas Cooperative Extension
For Kansas-specific cultivar recommendations, planting calendars, and pest pressure for pomelo, the canonical source is K-State Research and Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Pomelo native to Kansas?
No — the USDA PLANTS Database lists Pomelo as introduced rather than native in the Lower 48, so it is not part of Kansas's native flora. It grows here as a garden plant; pairing it with a few Kansas natives keeps local pollinators fed too.

Common Questions About Growing Pomelo in Kansas
When can I plant Pomelo 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 Pomelo, 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 Pomelo grown in across Kansas?
Kansas spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Pomelo carries a range of zones 9-11, 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). Pomelo 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. In cooler counties like Greeley, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Pomelo native to Kansas?
No — the USDA PLANTS Database lists Pomelo as introduced rather than native in the Lower 48, so it is not part of Kansas's native flora. It grows here as a garden plant; pairing it with a few Kansas natives keeps local pollinators fed too.
How should I amend the soil for Pomelo in Kansas?
Pomelo tolerates pH 4.5-8 and well (dry spells) drainage (FAO ECOCROP). That is a 3.5-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Kansas site — amend for drainage and organic matter first.
Will Pomelo actually grow on my specific land in Kansas?
