Can I Grow Pin Cherry in Maine?

Pin Cherry 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 pin cherry (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 Pin Cherry in Maine

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 cherry survives winter here. 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

Pin Cherry tolerates a wide pH range (pH 4.5-7.5) — 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 5.5 and 6.3 — 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, raised beds or amendment with compost solve it.

What Else to Consider for Pin Cherry 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 pin cherry — is covered on the Maine growing guide.

Timing shifts within Maine

Pin Cherry needs about 240 days of frost-free season to complete its cycle. No Maine county gives it that outdoors: even Knox County, the state’s longest season at 222 frost-free days, falls 18 days short — so it needs transplants, a short-season variety, or covered growing.

Across Maine’s 16 counties the frost-free season runs from 143 days in Franklin County to 222 days in Knox County — a spread of 79 days, which is why a single statewide planting date misleads. The median Maine county sees 182 frost-free days, which is 58 days short of what pin cherry needs — so on a typical Maine parcel this is a transplant-or-protect crop, not a direct-sow one.

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"). Pin Cherry's 240-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

Pin Cherry draws honeybees, native bees, and butterflies (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, pin cherry 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.

Maine Cooperative Extension

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

Is Pin Cherry native to Maine?

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

What pests threaten pin cherry in Maine?

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

Japanese beetle

Worth watching

The University of Kentucky lists this among the landscape plants Japanese beetles are most likely to attack, and the skeletonized, lace-like leaves can look alarming. But the honest calibration is the University of Minnesota's: a healthy, established tree, shrub or vine tolerates a lot of this feeding without significant, long-term injury — in most cases the damage is cosmetic and will not kill the plant.

What to do: For an established planting the move is to leave it be and keep it watered through the four-to-six-week flight — a vigorous plant outgrows feeding that looks worse than it is. Young or already-stressed plants are the exception and worth hand-protecting: knock beetles into soapy water in the cool of morning, when they are slow. The one thing not to hang is a Japanese beetle trap — University of Kentucky research found the lures pull in far more beetles than they catch.
