Langlade County, in Wisconsin, sits in USDA hardiness zone 4b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Expect cabbage, cranberry, turkish rocket, and collard greens to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Langlade County lies within the Northwoods (Northern Wisconsin) — a regional growing area with its own character.

Zone 4b is Langlade County's average, not your lot's — a low corner or a tree line moves it. Against Langlade County's 151-day season, see what your own ground reads.
Heat in Langlade County
Across a year, Langlade County accumulates about 1,640 growing degree days above 50°F, about 510 fewer than the middle Wisconsin county — ahead of 7 of Wisconsin’s 72 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 Langlade County
Across Langlade County, the ground is predominantly Alfisols, where Kennan, Antigo, and Pence are the most extensive named soil series. The soil is generally well drained with a silt loam surface. Topsoil pH runs about 5.5–5.9, moderately acidic. Rainfall drains through hydrologic group A soils.

How the ground varies across Langlade County
The USDA soil survey maps 48% of Langlade County as well drained — but another 50% drains differently: 17% somewhat poorly drained, 11% somewhat excessively drained.
Kennan is the most extensive named soil at 25% of mapped acres, then Antigo (21%) and Pence (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 Langlade County
Each reading below is measured for Langlade 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 Langlade County are well drained, in hydrologic group A — 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 Langlade County runs about pH 5.5–5.9, 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
Wet ground
MeasuredAbout 17% of Langlade County is mapped as hydric — wetland — soil.
If your lot falls in one of those pockets, a standard in-ground bed will fight waterlogging all season, and roots that need air will struggle.
Check how your own ground drains before you dig; raised beds or moisture-loving plantings turn a wet corner from a problem into a niche.
USDA NRCS SSURGO
Season length
MeasuredLanglade County runs about 151 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.

The kind of country Langlade County is in
Langlade County spans 2 EPA Level III ecoregions — Northern Lakes and Forests (55%) and North Central Hardwood Forests (45%). 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 Langlade County
We scored all 1,086 plants against Langlade County's own USDA zone 4b and its own 151-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 Wisconsin profile.
Is it too late to plant in Langlade County?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Apr 10; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 8 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 6 — long-season crops need about 90 days of runway, quick greens only 30. Even past midsummer there is room for a true fall garden here, and garlic planted near the close carries the momentum into next year.

What the federal record shows across Langlade County — and how to grow with it.
We checked the federal record across Langlade County — 445 documented sites across 7 of the 9 source types we track.
The most significant on record: 1 Superfund site (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Langlade 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.

What an experienced grower watches for around here
In and around Langlade County, Nitrate runs higher than the national average — 124 sites across Langlade County. That's not a problem with your land — it's information about 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 Langlade County
Everything above resolves to Langlade County as a whole — one PHZM band and one county frost record, read across 557K 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 Langlade 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 Langlade County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Langlade County
When does frost risk typically end in Langlade County?
The last hard freeze (28°F) in Langlade County typically lands around May 8, 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 29.
How long is the growing season in Langlade County?
Measured between 28°F hard freezes, Langlade County sees about 151 frost-free days — roughly May 8 through Oct 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 29 to Sep 22, about 116 days.
Is the soil safe to grow vegetables in Langlade County?
The federal record around Langlade County is a meaningful one — 445 documented sites, mostly Underground Storage Tanks entries (259), the nearest Underground Storage Tanks record about 0.6 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.
