Yes — Strong Match
pin oak (zones 4-8) covers every zone Massachusetts contains (5a-7b), so hardiness is not what limits it anywhere in the state.

Massachusetts is not one climate
Massachusetts’s winter-low ladder runs across 14 counties, from zone 5.5 in Berkshire County to zone 7.5 in Nantucket County. That is 20°F between the two counties’ average coldest night — the difference between pin oak overwintering in the ground and coming under cover.
The middle half of 14 counties runs 6–7 zones, with a median of 6.5 zones — a 2-zone span end to end.

When to Plant Pin Oak in Massachusetts
The frost window
Across Massachusetts, the last spring hard freeze (28°F) clears between Apr 4 and Apr 14, and the first fall hard freeze lands between Oct 24 and Nov 14 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 193-day window you can count on — up to 224 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
Massachusetts runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for pin oak, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether pin oak is a permanent planting or a replant-every-spring crop for you turns on your own zone within Massachusetts; check its hardiness range against that before treating it as long-lived ground.
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 pin oak survives winter here. Whether the season is long enough — and warm enough — is a different question.
Chill hours
Pin Oak requires ~400 chill hours (32-45°F dormancy window). Massachusetts 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
Pin Oak likes near-neutral soil (pH 5-7). That's the common-ground band across Massachusetts's glacial till and sandy loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 5.5 and 6.5 — worth knowing before you decide whether a Massachusetts soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Massachusetts site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Pin Oak in Massachusetts
Zone compatibility tells you about winter cold survival — but Massachusetts growers also need to think about:
Short growing season (120-180 frost-free days) limits warm-season crops
Rocky glacial soils require amendment in many areas
Late spring frosts can damage early plantings through mid-May
Deer pressure is significant in suburban and rural areas
What to actually do about these — and the constraints that apply to every Massachusetts grower, not just pin oak — is covered on the Massachusetts growing guide.
Where in Massachusetts Pin Oak Is Zone-Hardy
Pin Oak is rated for USDA zones 4–8. Every one of Massachusetts’s 14 counties sits inside that band — from Berkshire County at zone 5b to Nantucket County at zone 7b — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.
Across those 14 counties Massachusetts’s winter-low ladder runs from zone 5b in Berkshire County to zone 7b in Nantucket County — 2 USDA zones of spread, which is 20°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Berkshire County holds its last hard freeze (28°F) until about Apr 29, while Nantucket County is clear by Mar 26 — 34 days apart. Set pin oak out on your county’s date, not the state’s.

Massachusetts Cooperative Extension
For Massachusetts-specific cultivar recommendations, planting calendars, and pest pressure for pin oak, the canonical source is UMass Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Pin Oak native to Massachusetts?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Pin Oak as native to Massachusetts. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Pin Oak in Massachusetts
When can I plant Pin Oak in Massachusetts?
Massachusetts's last spring hard freeze (28°F) clears between Apr 4 and Apr 14, and the first fall hard freeze lands between Oct 24 and Nov 14 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Pin Oak, so this page does not state whether it overwinters in Massachusetts 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 Pin Oak grown in across Massachusetts?
Massachusetts spans USDA hardiness zones 5a-7b (USDA ARS PHZM 2023). Pin Oak carries a range of zones 4-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Massachusetts site have?
A typical Massachusetts site sees ~206 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Pin Oak should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Pin Oak native to Massachusetts?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Pin Oak as native to Massachusetts. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Pin Oak in Massachusetts?
Pin Oak prefers pH 5-7 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Massachusetts soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Pin Oak actually grow on my specific land in Massachusetts?
