Lowellville, Ohio, sits in USDA hardiness zone 6a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
These conditions suit cabbage, hazelnut, lavender, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

What this means for growing in Lowellville
Each reading below is measured for Lowellville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredLowellville runs about 195 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredLowellville sits in USDA hardiness zone 6a.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Lowellville is in
Lowellville sits in the Erie Drift Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Lowellville's own centroid rather than borrowed from Mahoning County.

Is it too late to plant in Lowellville?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Mar 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 19 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 31 — long-season crops need about 90 days of runway, quick greens only 30. Late in the year the fall bench takes over — quick greens, radishes, and garlic that repays you next summer.

What an experienced grower watches for around here
In and around Lowellville, two things run higher than the national average within ~10 miles of Lowellville — Toxics Release Inventory (59 sites) and Superfund (11 sites). That's not a problem with your land — it's information about it.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Lowellville
Everything above resolves to Lowellville as a whole — one PHZM band and one 28°F frost record, read across 871 acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Lowellville
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Lowellville’s own record; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Lowellville
When does frost risk typically end in Lowellville?
The last hard freeze (28°F) in Lowellville typically lands around Apr 19, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about May 10.
When is the first frost in Lowellville?
The first hard freeze (28°F) in Lowellville typically arrives around Oct 31, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 17, so the watching starts about Oct 1 — about 195 days after the spring freeze cleared.
How long is the growing season in Lowellville?
Measured between 28°F hard freezes, Lowellville sees about 195 frost-free days — roughly Apr 19 through Oct 31, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 10 to Oct 17, about 160 days.
Is the soil safe to grow vegetables in Lowellville?
The federal record around Lowellville is a meaningful one — 884 documented sites, mostly Underground Storage Tanks entries (454), the nearest Superfund record about 0.3 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Lowellville?
From about Oct 1 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Oct 31 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Oct 31. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Lowellville's scale — its 6a band and its 195-day season. Your yard writes its own version of Lowellville's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
