Wyoming County, in Pennsylvania, sits in USDA hardiness zone 6a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Expect cabbage, hazelnut, lavender, and collard greens to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.

Zone 6a is Wyoming County's average, not your lot's — a low corner or a tree line moves it. Against Wyoming County's 191-day season, see what your own ground reads.
Heat in Wyoming County
Across a year, Wyoming County accumulates about 2,415 growing degree days above 50°F, about 132 fewer than the middle Pennsylvania county — ahead of 23 of Pennsylvania’s 67 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.

Soil in Wyoming County
Across Wyoming County, the ground is predominantly Inceptisols, where Oquaga, Wellsboro, and Morris are the most extensive named soil series. The soil is generally well drained with a channery loam surface. Topsoil pH runs about 5.3–5.5, strongly acidic. Rainfall drains through hydrologic group D soils.

How the ground varies across Wyoming County
The USDA soil survey maps 44% of Wyoming County as well drained — but another 54% drains differently: 22% moderately well drained, 14% somewhat poorly drained.
Oquaga is the most extensive named soil at 16% of mapped acres, then Wellsboro (13%) and Morris (10%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Wyoming County
Each reading below is measured for Wyoming County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Wyoming County are well drained, in hydrologic group D — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Wyoming County runs about pH 5.3–5.5, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Season length
MeasuredWyoming County runs about 191 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
MeasuredWyoming County 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 Wyoming County is in
Wyoming County spans 2 EPA Level III ecoregions — Northern Allegheny Plateau (72%) and North Central Appalachians (28%). Which one your land falls in changes what grows wild there and how the ground behaves, and a county-wide answer cannot tell you which.
What Grows in Wyoming County
We scored all 1,086 plants against Wyoming County's own USDA zone 6a and its own 191-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Pennsylvania profile.
Is it too late to plant in Wyoming County?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Mar 20; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 17 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 25 — long-season crops need about 90 days of runway, quick greens only 30. As the window narrows, the plantings just get faster — fall brassicas, then greens, then garlic to finish.

What the federal record shows across Wyoming County — and how to grow with it.
We checked the federal record across Wyoming County — 245 documented sites across 5 of the 9 source types we track.
The most significant on record: 2 Toxics Release Inventory facilities. Active industrial facilities reporting chemical releases to air, water, and land.
There's a meaningful federal record across Wyoming County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.

A note from Gnorman
What an experienced grower watches for around here
In and around Wyoming County, Nitrate runs higher than the national average — 94 sites across Wyoming County. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Wyoming County
Everything above resolves to Wyoming County as a whole — one PHZM band and one county frost record, read across 254K 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 county 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 county average.

How we know this about Wyoming County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Wyoming County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Wyoming County
When does frost risk typically end in Wyoming County?
The last hard freeze (28°F) in Wyoming County typically lands around Apr 17, 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 8.
How long is the growing season in Wyoming County?
Measured between 28°F hard freezes, Wyoming County sees about 191 frost-free days — roughly Apr 17 through Oct 25, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 8 to Oct 11, about 156 days.
Is the soil safe to grow vegetables in Wyoming County?
The federal record around Wyoming County is a meaningful one — 245 documented sites, mostly Underground Storage Tanks entries (110), the nearest Nitrate record about 1.7 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.
