New Post, Wisconsin, sits in USDA hardiness zone 4a — a zone band wide enough that plant choice, not possibility, is the interesting question.
A short list that earns its place here — cabbage, cranberry, cilantro, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in New Post, no two yards are alike.

What this means for growing in New Post
Each reading below is measured for New Post itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredNew Post runs about 148 days between hard freezes — a short growing season.
Long-maturing crops like melons, sweet potatoes, and winter squash can run out of runway before the first hard freeze, ripening late or not at all.
Lead with fast-maturing varieties, and stretch the season on both ends with cold frames, low tunnels, or a greenhouse.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredNew Post sits in USDA hardiness zone 4a.
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 New Post is in
New Post sits in the Northern Lakes and Forests — EPA Level III, inside the wider Northern Forests. That is read at New Post's own centroid rather than borrowed from Sawyer County.

Is it too late to plant in New Post?
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 12; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 10 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 5 — long-season crops need about 90 days of runway, quick greens only 30. In a season this compact, fast finishers and cold-hardy greens do the late work, and garlic tucked in before the freeze repays you next summer.

What an experienced grower watches for around here
In and around New Post, Underground Storage Tanks runs higher than the national average — 64 sites within ~10 miles of New Post. That's not a problem with your land — it's information about it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside New Post
Everything above resolves to New Post as a whole — one PHZM band and one 28°F frost record, read across 13K 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 New Post
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 New Post’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 New Post
When does frost risk typically end in New Post?
The last hard freeze (28°F) in New Post typically lands around May 10, 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 31.
When is the first frost in New Post?
The first hard freeze (28°F) in New Post typically arrives around Oct 5, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 21, so the watching starts about Sep 5 — about 148 days after the spring freeze cleared.
How long is the growing season in New Post?
Measured between 28°F hard freezes, New Post sees about 148 frost-free days — roughly May 10 through Oct 5, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 31 to Sep 21, about 113 days.
Is the soil safe to grow vegetables in New Post?
The federal record around New Post is a meaningful one — 78 documented sites, mostly Underground Storage Tanks entries (64), the nearest Underground Storage Tanks record about 0.9 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 gardeners stretch the season in New Post?
With about 148 frost-free days between hard freezes, New Post rewards the classic extension moves: floating row cover buys roughly two to four extra weeks at each shoulder — on this season that is a working window nearer 176 to 204 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 10 hard-freeze normal stretches the season without touching the calendar.
