Can I Grow American Linden in Maine?

American Linden 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 american linden (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 American Linden 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 american linden 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

American Linden likes near-neutral soil (pH 6-8). That's the common-ground band across Maine'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 6.5 and 7.5 — 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 American Linden 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 american linden — 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 american linden 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 American Linden Is Zone-Hardy

American Linden is rated for USDA zones 2–8. Every one of Maine’s 16 counties sits inside that band — from Aroostook County at zone 4a to Lincoln County at zone 6a — 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 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 american linden 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". American Linden’s zone 2–8 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Pollinator + Wildlife Value

American Linden draws honeybees and native bees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, american linden 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 american linden, the canonical source is UMaine Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is American Linden native to Maine?

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

What pests threaten american linden in Maine?

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

Japanese beetle

Worth watching

Linden, birch and elm are named among the Japanese beetle's preferred trees, and the skeletonized leaves look alarming — but the University of Minnesota's read is that healthy, mature trees and shrubs tolerate a lot of feeding without significant, long-term injury.

What to do: For an established tree the honest move is to leave it alone and keep it watered through the flight. Young or already-stressed trees are the exception — those are worth protecting, and a beetle trap is the one thing not to hang, because it pulls beetles toward the tree rather than away.
