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 pawpaw 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 Pawpaw 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 pawpaw, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether pawpaw 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 pawpaw survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Pawpaw wants 130+ frost-free days; a typical Massachusetts site sees ~206 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Pawpaw needs ~2400 GDD (base 50°F) to ripen. The state median runs ~2506 GDD (from PRISM 1991-2020 climate normals), so Massachusetts sits right at the threshold — pay attention to siting and microclimate.
Chill hours
Pawpaw 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
Pawpaw likes near-neutral soil (pH 5.2-7.5). 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 6 and 7.2 — 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.

Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. Massachusetts soil profile from USDA NRCS SSURGO. Site-specific verification: a 30-minute soil test from your local Extension lab.
Before you plant pawpaw for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before pawpaw goes in. What follows is Massachusetts’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Massachusetts — and how to grow with it.
We checked the federal record across Massachusetts — 40,795 documented sites across 8 of the 9 source types we track.
The most significant on record: 417 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Massachusetts carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

What an experienced grower watches for around here
In and around Massachusetts, Brownfields runs higher than the national average — 23,042 sites across Massachusetts. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

What Else to Consider for Pawpaw 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 pawpaw — is covered on the Massachusetts growing guide.
Timing shifts within Massachusetts
Pawpaw needs about 130 days of frost-free season to complete its cycle. Even Berkshire County — Massachusetts’s shortest season at 171 frost-free days — clears that by 41 days, so season length isn’t the constraint anywhere in Massachusetts. What varies is your own parcel.
Across Massachusetts’s 14 counties the frost-free season runs from 171 days in Berkshire County to 246 days in Nantucket County — a spread of 75 days, which is why a single statewide planting date misleads. The median Massachusetts county sees 206 frost-free days, leaving pawpaw about 76 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"). Pawpaw'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
Pawpaw draws native bees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, pawpaw can only work that bloom inside Massachusetts's frost window — roughly 206 days, opening after the last 28°F freeze (Apr 4 - Apr 14) and closing at the first (Oct 24 - Nov 14), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Pawpaw in Massachusetts
When can I plant Pawpaw 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 Pawpaw, 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 Pawpaw grown in across Massachusetts?
Massachusetts spans USDA hardiness zones 5a-7b (USDA ARS PHZM 2023). Pawpaw carries a range of zones 5-9, 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). Pawpaw needs 130+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Pawpaw native to Massachusetts?
Pawpaw is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Massachusetts. It can still earn a place in a Massachusetts garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Pawpaw in Massachusetts?
Pawpaw prefers pH 5.2-7.5 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.
