Hannasville, Pennsylvania, 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.
Growers here do well with cabbage, hazelnut, lavender, and collard greens — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Hannasville, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Hannasville lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Hannasville
Each reading below is measured for Hannasville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredHannasville runs about 188 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.

Winter hardiness
MeasuredHannasville 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 Hannasville is in
Hannasville sits in the Erie Drift Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Hannasville's own centroid, and it is not what its county reads: Venango County is mostly North Central Appalachians. The wider page above you is answering a different question about different ground.

Is it too late to plant in Hannasville?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Mar 28; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 25 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 30 — long-season crops need about 90 days of runway, quick greens only 30. The tail of the season still works: sixty-day crops into late summer, quick greens after, garlic last of all.

What an experienced grower watches for around here
In and around Hannasville, two things run higher than the national average within ~10 miles of Hannasville — Toxics Release Inventory (19 sites) and Superfund (3 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 Hannasville
Everything above resolves to Hannasville as a whole — one PHZM band and one 28°F frost record, read across 991 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 Hannasville
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 Hannasville’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 Hannasville
When does frost risk typically end in Hannasville?
The last hard freeze (28°F) in Hannasville typically lands around Apr 25, 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 16.
When is the first frost in Hannasville?
The first hard freeze (28°F) in Hannasville typically arrives around Oct 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 16, so the watching starts about Sep 30 — about 188 days after the spring freeze cleared.
How long is the growing season in Hannasville?
Measured between 28°F hard freezes, Hannasville sees about 188 frost-free days — roughly Apr 25 through Oct 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 16 to Oct 16, about 153 days.
Is the soil safe to grow vegetables in Hannasville?
The federal record around Hannasville is a meaningful one — 197 documented sites, mostly Underground Storage Tanks entries (102), the nearest Underground Storage Tanks record about 2.3 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 Hannasville?
From about Sep 30 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 30 (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 30. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Hannasville's scale — its 6a band and its 188-day season. Your yard writes its own version of Hannasville's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
