Can I Grow Apricot in Maine?

Apricot in Maine — the short answer

Maine is not one climate

Where in Maine Fits Best

Even within Maine's zones 3b-7a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for apricot (USDA PHZM 2023):

Zone Comparison

Plant data: Growable Ground Plant Database, compiled from FAO ECOCROP, USDA PLANTS, and university Extension sources — per-field provenance varies and is published with the dataset. State data: USDA ARS PHZM 2023, NOAA Climate Normals, NRCS SSURGO.

When to Plant Apricot in Maine

Timing tuned to sub-state frost dates — Piscataquis 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 apricot survives winter in part of Maine, not across all of it. Whether the season is long enough — and warm enough — is a different question.

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

Apricot tolerates a wide pH range (pH 5-8) — 3 units, acid ground through alkaline — so soil acidity is rarely what limits it in Maine. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 6.5 and 7 — worth knowing before you decide whether a Maine soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Maine site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost.

Plant pH requirements: FAO ECOCROP and USDA PLANTS, with the remaining rows from other published sources or Growable Ground compilation. Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. Maine soil profile from USDA NRCS SSURGO. Site-specific verification: a 30-minute soil test from your local Extension lab.

Before you plant apricot 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 apricot goes in. What follows is Maine’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 Maine — and how to grow with it.

Federal record: High

We checked the federal record across Maine — 7,879 documented sites across 7 of the 8 source types we track.

The most significant on record: 99 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.

Maine 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 of imported, lab-tested soil grow well almost anywhere in the meantime.

A note from Gnorman

What an experienced grower watches for around here

In and around Maine, Brownfields runs higher than the national average — 961 sites across Maine. 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 that EPA’s Brownfields program (ACRES) has assessed or funded cleanup on.

Contact the EPA Brownfields program or the state cleanup agency for this site’s actual assessment/remediation status — ACRES itself does not publish one we can read per site.

What Else to Consider for Apricot in Maine

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

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

Timing shifts within Maine

Maine isn't one climate. In Piscataquis County, the last hard freeze (28°F) holds until about May 15 — roughly 23 days later than the recorded state median — so plant apricot to your county's window, not the statewide date.

County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.

Where in Maine Apricot Is Zone-Hardy

Apricot is rated for USDA zones 5–9. 12 of Maine’s 16 counties fall inside that band. The coldest that does is Oxford County at zone 5a. 4 counties sit below the plant’s zone 5 floor, where an unprotected plant is relying on snow cover and a mild year. Where you are in Maine decides this one.

Across those 16 counties Maine’s winter-low ladder runs from zone 4a in Aroostook County to zone 6a in Lincoln 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. Piscataquis County holds its last hard freeze (28°F) until about May 15, while Knox County is clear by Apr 4 — 41 days apart. Set apricot out on your county’s date, not the state’s.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Apricot’s zone 5–9 band: Rated hardy to zone 5a by NC State Extension Gardener Plant Toolbox, checked Oct 2026. Ceiling: not verified.. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Pollinator + Wildlife Value

Apricot draws honeybees, native bees, and butterflies (high value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, apricot can only work that bloom inside Maine's frost window — roughly 182 days, opening after the last 28°F freeze (Apr 16 - May 3) and closing at the first (Oct 10 - Oct 24), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Good to Know Before You Plant Apricot

Maine Cooperative Extension

For Maine-specific cultivar recommendations, planting calendars, and pest pressure for apricot, the canonical source is UMaine Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Apricot native to Maine?

No — the USDA PLANTS Database lists Apricot as introduced rather than native in the Lower 48, so it is not part of Maine's native flora. It grows here as a garden plant; pairing it with a few Maine natives keeps local pollinators fed too.

Looking for plants that belong here? The Maine growing guide lists plants that USDA PLANTS records growing in Maine and that Kew and NatureServe Explorer both list in its native range, leaving out any that NatureServe flags as exotic there or that our audit holds.

What pests threaten apricot in Maine?

Japanese beetle is documented in Maine and will find apricot, but it is manageable here. What an experienced grower watches for, and does:

Japanese beetle

Worth watching

Japanese beetles feed readily on Prunus fruit and nut trees — the University of Kentucky lists cherries, plums, peaches and their relatives among the plants likely to be attacked. The University of Minnesota's read keeps it in proportion: fruits and their trees tolerate limited leaf feeding, and in most cases the damage is cosmetic rather than a threat to the harvest.

What to do: Protect it through the few peak weeks of midsummer, not all season. Handpick beetles into soapy water in the cool of morning, harvest regularly through July and August to take feeding pressure off the fruit, and keep the tree well watered. Do not hang a Japanese beetle trap — the lures draw in more beetles than they remove.
