Unlikely — Zone Mismatch
pangola grass (zones 9-13) does not overlap with Ohio's zone range (5b-7a). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Pangola Grass is hardy to zone 9, and the warmest ground in Ohio is zone 7 — 2 zones short. Planted in open ground it will not survive a Ohio winter. To grow it here, grow pangola grass under glass — a greenhouse is the only lift this wide the engine models.

Your yard isn't the whole zone.
Ohio spans zones 5b-7a, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score pangola grass against your land's actual soil, sun, and frost.

When to Plant Pangola Grass in Ohio
The frost window
Across Ohio, the last spring hard freeze (28°F) clears between Apr 5 and Apr 13, and the first fall hard freeze lands between Oct 31 and Nov 6 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 201-day window you can count on — up to 215 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.
Frost tenderness
Pangola Grass is frost-tender — its listed minimum temperature is 42.8°F (USDA PLANTS Database) — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does.
Timing tuned to sub-state frost dates — Geauga 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.
Growing Season Fit
The zone check says pangola grass does not survive a Ohio 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 Ohio under protection.
Frost-free days
Pangola Grass wants 80+ frost-free days; a typical Ohio site sees ~208 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
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
Pangola Grass tolerates a wide pH range (pH 4.5-9) — 4.5 units, acid ground through alkaline — so soil acidity is rarely what limits it in Ohio. 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 and 7 — worth knowing before you decide whether a Ohio soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells), excessive (dry/moderately dry). If your Ohio 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 28.6% of Ohio as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Pangola Grass sits mid-range for drought tolerance, so either extreme can cost you — your soil map unit, not the state average, is the real answer.

Pangola Grass in Ohio — Quick Answer
- Verdict: Unlikely — Zone Mismatch
- Plant Zones: 9-13 (USDA PLANTS Database)
- State Zones: 5b-7a (USDA ARS PHZM 2023)

What Else to Consider for Pangola Grass in Ohio
Zone compatibility tells you about winter cold survival — but Ohio growers also need to think about:
Heavy clay soils across much of northern Ohio require amendment for drainage
Variable spring weather with late frost risk through mid-May
Japanese beetles and tomato hornworms are common garden pests
Wet springs can delay planting and promote root rot
Growing pangola grass here specifically
Pangola Grass likes pH 4.5–9.0 and takes cold to about 42°F, yet neither saves it from wet feet — SSURGO maps about 28.6% of Ohio poorly-drained, where its roots sit and rot.
Set pangola grass high on bermed, grit-amended ground so winter and storm water drain away from the roots. How to handle it →
What to actually do about these — and the constraints that apply to every Ohio grower, not just pangola grass — is covered on the Ohio growing guide.
Timing shifts within Ohio
Ohio isn't one climate. In Geauga County, the last hard freeze (28°F) holds until about Apr 22 — roughly 13 days later than the recorded state median — so plant pangola grass to your county's window, not the statewide date.
Pangola Grass needs about 80 days of frost-free season to complete its cycle. Even Columbiana County — Ohio’s shortest season at 182 frost-free days — clears that by 102 days, so season length isn’t the constraint anywhere in Ohio. 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"). Pangola Grass's 80-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Common Questions About Growing Pangola Grass in Ohio
When can I plant Pangola Grass in Ohio?
Ohio's last spring hard freeze (28°F) clears between Apr 5 and Apr 13, and the first fall hard freeze lands between Oct 31 and Nov 6 (NOAA Regional Climate Centers ACIS, 1991-2020). Pangola Grass is frost-tender — its listed minimum temperature is 42.8°F (USDA PLANTS Database) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
What hardiness zone is Pangola Grass grown in across Ohio?
Ohio spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Pangola Grass 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 Ohio site have?
A typical Ohio site sees ~208 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Pangola Grass needs 80+ 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 Geauga, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for Pangola Grass in Ohio?
Pangola Grass tolerates pH 4.5-9 and well (dry spells), excessive (dry/moderately dry) drainage (FAO ECOCROP). That is a 4.5-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Ohio site — amend for drainage and organic matter first.
Will Pangola Grass actually grow on my specific land in Ohio?
