Glenbeulah, Wisconsin, sits in USDA hardiness zone 5b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Growers here do well with cabbage, cranberry, lavender, and collard greens — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Glenbeulah, 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 Glenbeulah 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 Glenbeulah
Each reading below is measured for Glenbeulah itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredGlenbeulah runs about 181 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
MeasuredGlenbeulah sits in USDA hardiness zone 5b.
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 Glenbeulah is in
Glenbeulah sits in the Southeastern Wisconsin Till Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Glenbeulah's own centroid rather than borrowed from Sheboygan County.

Is it too late to plant in Glenbeulah?
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 24; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 21 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 19 — long-season crops need about 90 days of runway, quick greens only 30. Late in the year the fall bench takes over — quick greens, radishes, and garlic that repays you next summer.

What an experienced grower watches for around here
In and around Glenbeulah, two things run higher than the national average within ~10 miles of Glenbeulah — CAFO (5 sites) and Underground Storage Tanks (261 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Glenbeulah
Everything above resolves to Glenbeulah as a whole — one PHZM band and one 28°F frost record, read across 445 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 Glenbeulah
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 Glenbeulah’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 Glenbeulah
When does frost risk typically end in Glenbeulah?
The last hard freeze (28°F) in Glenbeulah typically lands around Apr 21, 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 12.
When is the first frost in Glenbeulah?
The first hard freeze (28°F) in Glenbeulah typically arrives around Oct 19, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 5, so the watching starts about Sep 19 — about 181 days after the spring freeze cleared.
How long is the growing season in Glenbeulah?
Measured between 28°F hard freezes, Glenbeulah sees about 181 frost-free days — roughly Apr 21 through Oct 19, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 12 to Oct 5, about 146 days.
Is the soil safe to grow vegetables in Glenbeulah?
The federal record around Glenbeulah is a meaningful one — 422 documented sites, mostly Underground Storage Tanks entries (261), the nearest Nitrate record under a tenth of a mile 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 Glenbeulah?
From about Sep 19 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 19 (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 19. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Glenbeulah's scale — its 5b band and its 181-day season. Your yard writes its own version of Glenbeulah's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
