Vermont is not one climate
Vermont’s winter-low ladder runs across 14 counties, from zone 4.5 in Caledonia County to zone 5.5 in Windsor County. That is 10°F between the two counties’ average coldest night — the difference between blueberry overwintering in the ground and coming under cover.
The middle half of 14 counties runs 4.5–5 zones, with a median of 5 zones — a 1-zone span end to end.

When to Plant Blueberry in Vermont
The frost window
Across Vermont, the last spring hard freeze (28°F) clears between Apr 27 and May 5, and the first fall hard freeze lands between Oct 10 and Oct 17 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 158-day window you can count on — up to 173 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
Vermont runs as cold as USDA zone 4, and no sourced winter-hardiness floor is on record for blueberry, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether blueberry is a permanent planting or a replant-every-spring crop for you turns on your own zone within Vermont; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Essex 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 blueberry survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Blueberry wants 160+ frost-free days; a typical Vermont site sees ~163 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a tight window — use transplants and pick early-maturing cultivars.
Growing degree days
Blueberry needs ~1500 GDD (base 50°F) to ripen. The state median runs ~1746 GDD (from PRISM 1991-2020 climate normals), so Vermont sits right at the threshold — pay attention to siting and microclimate.
Chill hours
Blueberry requires ~800 chill hours (32-45°F dormancy window). Vermont 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
Blueberry prefers acidic soil (pH 3-5.5). Vermont's glacial till can run on the acidic side, which often aligns well — confirm with a soil test before planting. It will grow across that whole span, but it does best between pH 4 and 5.5 — worth knowing before you decide whether a Vermont soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Vermont 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 18.5% of Vermont as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Blueberry has low drought tolerance, so it is the fast-draining end that will cost you — your soil map unit, not the state average, is the real answer.

Before you plant blueberry 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 blueberry goes in. What follows is Vermont’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 Vermont — and how to grow with it.
We checked the federal record across Vermont — 6,987 documented sites across 8 of the 9 source types we track.
The most significant on record: 41 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Vermont 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.

Highest-Severity Sites
Know Before You Grow
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

What Else to Consider for Blueberry in Vermont
Zone compatibility tells you about winter cold survival — but Vermont growers also need to think about:
Short growing season (100-130 frost-free days)
Rocky soils throughout the Green Mountains
Heavy clay in the Champlain Valley
Growing blueberry here specifically
Blueberry likes pH 3.0–5.5 and its growing tissue burns around 30°F (FAO ECOCROP), yet neither saves it from wet feet — SSURGO maps about 18.5% of Vermont poorly-drained, where its crown sit and rot.
Set blueberry high on bermed, grit-amended ground so winter and storm water drain away from the crown. How to handle it →
What to actually do about these — and the constraints that apply to every Vermont grower, not just blueberry — is covered on the Vermont growing guide.
Timing shifts within Vermont
Vermont isn't one climate. In Essex County, the last hard freeze (28°F) holds until about May 13 — roughly 11 days later than the recorded state median — so plant blueberry to your county's window, not the statewide date.
Blueberry needs about 160 days of frost-free season to complete its cycle. 9 of Vermont’s 14 counties give it that outright. The tightest that does is Bennington County at 160 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
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"). Blueberry's 160-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
Blueberry draws honeybees and native bees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, blueberry can only work that bloom inside Vermont's frost window — roughly 163 days, opening after the last 28°F freeze (Apr 27 - May 5) and closing at the first (Oct 10 - Oct 17), per NOAA Regional Climate Centers ACIS, 1991-2020.
Vermont Cooperative Extension
For Vermont-specific cultivar recommendations, planting calendars, and pest pressure for blueberry, the canonical source is UVM Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Blueberry native to Vermont?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Blueberry as native to Vermont. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Blueberry in Vermont
When can I plant Blueberry in Vermont?
Vermont's last spring hard freeze (28°F) clears between Apr 27 and May 5, and the first fall hard freeze lands between Oct 10 and Oct 17 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Blueberry, so this page does not state whether it overwinters in Vermont 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 Blueberry grown in across Vermont?
Vermont spans USDA hardiness zones 4a-6a (USDA ARS PHZM 2023). Blueberry 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 Vermont site have?
A typical Vermont site sees ~163 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Blueberry needs 160+ 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 Essex, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Blueberry native to Vermont?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Blueberry as native to Vermont. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Blueberry in Vermont?
Blueberry prefers pH 3-5.5 and well (dry spells) drainage (FAO ECOCROP). Most Vermont soils run mildly acidic to neutral; many sites land near this band naturally, and a soil test plus targeted sulfur or organic amendment closes any gap.
