Wisconsin is not one climate

Wisconsin’s winter-low ladder runs across 72 counties, from zone 4 in Bayfield County to zone 6 in Racine County. That is 20°F between the two counties’ average coldest night — the difference between sugar maple overwintering in the ground and coming under cover.

The middle half of 72 counties runs 4.55 zones, with a median of 4.5 zones — a 2-zone span end to end.

Even within Wisconsin's zones 3b-6a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for sugar maple (USDA PHZM 2023):

When to Plant Sugar Maple in Wisconsin

The frost window

Across Wisconsin, the last spring hard freeze (28°F) clears between Apr 17 and May 2, and the first fall hard freeze lands between Oct 9 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 160-day window you can count on — up to 187 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.

Winter standing

Wisconsin runs as cold as USDA zone 3, and no sourced winter-hardiness floor is on record for sugar maple, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether sugar maple is a permanent planting or a replant-every-spring crop for you turns on your own zone within Wisconsin; check its hardiness range against that before treating it as long-lived ground.

Timing tuned to sub-state frost dates — Florence County, not the statewide average.

Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.

Growing Season Fit

The zone check says sugar maple survives winter here. Whether the season is long enough — and warm enough — is a different question.

Frost-free days

Sugar Maple wants 130+ frost-free days; a typical Wisconsin site sees ~173 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.

Chill hours

Sugar Maple requires ~1200 chill hours (32-45°F dormancy window). Wisconsin typically banks ~2500 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.

GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.

Soil + Drainage Fit

Sugar Maple likes near-neutral soil (pH 5.3-7.3). That's the common-ground band across Wisconsin's silt loam and clay loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 6.5 — worth knowing before you decide whether a Wisconsin soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Wisconsin site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Your land, not the state average

SSURGO maps about 19.9% of Wisconsin as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Sugar Maple sits mid-range for drought tolerance, so either extreme can cost you — your soil map unit, not the state average, is the real answer.

What Else to Consider for Sugar Maple in Wisconsin

Zone compatibility tells you about winter cold survival — but Wisconsin growers also need to think about:

Cold winters (-30F in northern WI)

Short growing season (110-140 frost-free days)

Sandy central soils drain too quickly

Growing sugar maple here specifically

Sugar Maple needs sharp drainage and sends deep roots; its growing tissue takes cold to about 30°F (FAO ECOCROP), but in Wisconsin, about 19.9% of soils are poorly-drained (SSURGO), and standing water is what actually kills it.

What to actually do about these — and the constraints that apply to every Wisconsin grower, not just sugar maple — is covered on the Wisconsin growing guide.

Timing shifts within Wisconsin

Wisconsin isn't one climate. In Florence County, the last hard freeze (28°F) holds until about May 16 — roughly 21 days later than the recorded state median — so plant sugar maple to your county's window, not the statewide date.

Sugar Maple needs about 130 days of frost-free season to complete its cycle. Even Florence County — Wisconsin’s shortest season at 140 frost-free days — clears that by 10 days, so season length isn’t the constraint anywhere in Wisconsin. What varies is your own parcel.

Across Wisconsin’s 72 counties the frost-free season runs from 140 days in Florence County to 217 days in Milwaukee County — a spread of 77 days, which is why a single statewide planting date misleads. The median Wisconsin county sees 173 frost-free days, leaving sugar maple about 43 days of slack on a typical parcel — room for a second sowing where the season runs long.

County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Sugar Maple's 130-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Pollinator + Wildlife Value

Sugar Maple draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, sugar maple can only work that bloom inside Wisconsin's frost window — roughly 173 days, opening after the last 28°F freeze (Apr 17 - May 2) and closing at the first (Oct 9 - Oct 21), per NOAA Regional Climate Centers ACIS, 1991-2020.

Wisconsin Cooperative Extension

For Wisconsin-specific cultivar recommendations, planting calendars, and pest pressure for sugar maple, the canonical source is UW–Madison Division of Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Sugar Maple native to Wisconsin?

Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Sugar Maple as native to Wisconsin. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Sugar Maple in Wisconsin

When can I plant Sugar Maple in Wisconsin?

Wisconsin's last spring hard freeze (28°F) clears between Apr 17 and May 2, and the first fall hard freeze lands between Oct 9 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Sugar Maple, so this page does not state whether it overwinters in Wisconsin and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.

What hardiness zone is Sugar Maple grown in across Wisconsin?

Wisconsin spans USDA hardiness zones 3b-6a (USDA ARS PHZM 2023). Sugar Maple carries a range of zones 3-8, so the overlap zones are where outdoor growing is most reliable.

How many frost-free days does a typical Wisconsin site have?

A typical Wisconsin site sees ~173 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Sugar Maple needs 130+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Florence, the freeze-free season runs shorter than the state average, so verify your own county's window.

Is Sugar Maple native to Wisconsin?

Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Sugar Maple as native to Wisconsin. Planting it supports the pollinators and wildlife that evolved alongside it.

How should I amend the soil for Sugar Maple in Wisconsin?

Sugar Maple prefers pH 5.3-7.3 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Wisconsin soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
