Ohio is not one climate

Ohio’s winter-low ladder runs across 88 counties, from zone 6 in Allen County to zone 7 in Scioto County. That is 10°F between the two counties’ average coldest night — the difference between maidenhair fern overwintering in the ground and coming under cover.

The middle half of 88 counties runs 66.5 zones, with a median of 6.5 zones — a 1-zone span end to end.

Where in Ohio Fits Best

Even within Ohio's zones 5b-7a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for maidenhair fern (USDA PHZM 2023):

When to Plant Maidenhair Fern 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.

Winter standing

Ohio runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for maidenhair fern, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether maidenhair fern is a permanent planting or a replant-every-spring crop for you turns on your own zone within Ohio; check its hardiness range against that before treating it as long-lived ground.

Timing tuned to sub-state frost dates — Geauga 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.

Soil + Drainage Fit

Maidenhair Fern likes near-neutral soil (pH 4.6-6.6). That's the common-ground band across Ohio's glacial till and clay loam — a soil test confirms it for your site. Drainage requirement: poorly (saturated >50% of year). A soil-survey lookup (NRCS SSURGO) flags whether your specific site matches.

Your land, not the state average

Ohio's soils run mostly silt loam, but SSURGO maps the series, texture, and drainage under your exact parcel. What matters for maidenhair fern is the horizon its roots actually work, not the surface. That map unit, not the state average, decides how maidenhair fern performs.

What Else to Consider for Maidenhair Fern 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 maidenhair fern here specifically

Maidenhair Fern needs pH 4.6–6.6; Ohio's dominant silt loam soils may or may not deliver that, so your parcel's SSURGO map unit is the real test.

Start with a soil test on your own ground and adjust pH and texture to fit maidenhair fern's 4.6–6.6 range. How to handle it →

What to actually do about these — and the constraints that apply to every Ohio grower, not just maidenhair fern — 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 maidenhair fern 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 Ohio Maidenhair Fern Is Zone-Hardy

Maidenhair Fern is rated for USDA zones 410. Every one of Ohio’s 88 counties sits inside that band — from Allen County at zone 6a to Scioto County at zone 7a — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.

Across those 88 counties Ohio’s winter-low ladder runs from zone 6a in Allen County to zone 7a in Scioto County 1 USDA zone of spread, which is 10°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.

The planting window moves with it. Geauga County holds its last hard freeze (28°F) until about Apr 22, while Cuyahoga County is clear by Mar 30 23 days apart. Set maidenhair fern out on your county’s date, not the state’s.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Maidenhair Fern’s zone 410 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Recommended Maidenhair Fern Varieties for Ohio

Ohio publishes no state variety trial for maidenhair fern, so we won't invent a "best for Ohio" list. Choose types rated to your USDA hardiness zone (5b-7a), and confirm winter survival and drainage against your own parcel.

Ohio Cooperative Extension

For Ohio-specific cultivar recommendations, planting calendars, and pest pressure for maidenhair fern, the canonical source is Ohio State University Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Maidenhair Fern native to Ohio?

Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Maidenhair Fern as native to Ohio. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Maidenhair Fern in Ohio

When can I plant Maidenhair Fern 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). No sourced winter-hardiness floor is on record for Maidenhair Fern, so this page does not state whether it overwinters in Ohio 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 Maidenhair Fern grown in across Ohio?

Ohio spans USDA hardiness zones 5b-7a (USDA ARS PHZM 2023). Maidenhair Fern carries a range of zones 4-10, 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). Maidenhair Fern 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 Geauga, the freeze-free season runs shorter than the state average, so verify your own county's window.

Is Maidenhair Fern native to Ohio?

Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Maidenhair Fern as native to Ohio. Planting it supports the pollinators and wildlife that evolved alongside it.

How should I amend the soil for Maidenhair Fern in Ohio?

Maidenhair Fern prefers pH 4.6-6.6 and poorly (saturated >50% of year) drainage (USDA PLANTS). That sits in the common-ground band across Ohio soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
