Long Lake, Wisconsin, sits in USDA hardiness zone 4b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Among the crops suited to this profile: cabbage, cranberry, cilantro, and collard greens. The site-level story — soil, sun, drainage — decides the rest.
Even in Long Lake, 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 Long Lake 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 Long Lake
Each reading below is measured for Long Lake itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredLong Lake runs about 135 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.

Winter hardiness
MeasuredLong Lake sits in USDA hardiness zone 4b.
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 Long Lake is in
Long Lake sits in the Northern Lakes and Forests — EPA Level III, inside the wider Northern Forests. That is read at Long Lake's own centroid rather than borrowed from Florence County.

Is it too late to plant in Long Lake?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Apr 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 19 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 1 — long-season crops need about 90 days of runway, quick greens only 30. When the window is tight, the fall moves are quick ones — baby greens, radishes, and garlic set for next season.

A note from Gnorman
What an experienced grower watches for around here
In and around Long Lake, two things run higher than the national average within ~10 miles of Long Lake — Superfund (3 sites) and Nitrate (28 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).
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 Long Lake
Everything above resolves to Long Lake as a whole — one PHZM band and one 28°F frost record, read across 169 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 Long Lake
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 Long Lake’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 Long Lake
When does frost risk typically end in Long Lake?
The last hard freeze (28°F) in Long Lake typically lands around May 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 Jun 9.
When is the first frost in Long Lake?
The first hard freeze (28°F) in Long Lake typically arrives around Oct 1, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 17, so the watching starts about Sep 1 — about 135 days after the spring freeze cleared.
How long is the growing season in Long Lake?
Measured between 28°F hard freezes, Long Lake sees about 135 frost-free days — roughly May 19 through Oct 1, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 9 to Sep 17, about 100 days.
Is the soil safe to grow vegetables in Long Lake?
The federal record around Long Lake is a meaningful one — 55 documented sites, mostly Nitrate entries (28), the nearest Underground Storage Tanks record about 0.1 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 Long Lake?
With about 135 frost-free days between hard freezes, Long Lake 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 163 to 191 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 19 hard-freeze normal stretches the season without touching the calendar.
