Hoonah-Angoon Census Area, in Alaska, sits in USDA hardiness zones 4b-8a — a zone band wide enough that plant choice, not possibility, is the interesting question.
A short list that earns its place here — cabbage, blueberry, turkish rocket, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Hoonah-Angoon Census Area lies within the Southeast Alaska / Inside Passage Panhandle — a regional growing area with its own character.

Hardiness Zone Range
Zones 4B–8A
Zones in Hoonah-Angoon Census Area. Alaska and Hawaii zones come from USDA's separate 2023 AK/HI maps; the national thumbnail map covers the lower 48 only, so the range is shown as text here.
Zone 4b-8a is Hoonah-Angoon Census Area's average, not your lot's — a low corner or a tree line moves it. Against Hoonah-Angoon Census Area's 237-day season, see what your own ground reads.
Soil in Hoonah-Angoon County
Across Hoonah-Angoon County, the ground is predominantly Spodosols, where Tolstoi, McGilvery, and Kupreanof are the most extensive named soil series. The soil is generally well drained with a bedrock surface. Topsoil pH runs about 4.8–5.3, very strongly acidic. Rainfall drains through hydrologic group D soils.

How the ground varies across Hoonah-Angoon Census Area
The USDA soil survey maps 15% of Hoonah-Angoon Census Area as well drained — but another 36% drains differently: 14% moderately well drained, 8% somewhat poorly drained.
Tolstoi is the most extensive named soil at 10% of mapped acres, then McGilvery (4%) and Kupreanof (4%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Hoonah-Angoon Census Area
Each reading below is measured for Hoonah-Angoon Census Area itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Hoonah-Angoon Census Area are well drained, in hydrologic group D — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Hoonah-Angoon Census Area runs about pH 4.8–5.3, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Wet ground
MeasuredAbout 26% of Hoonah-Angoon Census Area is mapped as hydric — wetland — soil.
If your lot falls in one of those pockets, a standard in-ground bed will fight waterlogging all season, and roots that need air will struggle.
Check how your own ground drains before you dig; raised beds or moisture-loving plantings turn a wet corner from a problem into a niche.
USDA NRCS SSURGO
Season length
MeasuredHoonah-Angoon Census Area runs about 237 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.

What Grows in Hoonah-Angoon Census Area
We scored all 1,085 plants against Hoonah-Angoon Census Area's own USDA zone 4b-8a and its own 237-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Alaska profile.

Is it too late to plant in Hoonah-Angoon Census Area?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 26; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 26 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 18 — long-season crops need about 90 days of runway, quick greens only 30. With a season this long, “too late” mostly means “switch crops” — second sowings and a full fall garden are the norm, with garlic closing the year.
Safe to Grow Here?
What the federal record shows across Hoonah-Angoon County — and how to grow with it.
We checked the federal record across Hoonah-Angoon County — 304 documented sites across 6 of the 8 source types we track.
The most significant on record: 3 Superfund sites (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Hoonah-Angoon Census Area 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.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 8 federal source types.

What an experienced grower watches for around here
In and around Hoonah-Angoon Census Area, Mining runs higher than the national average — 285 sites across Hoonah-Angoon County. That's not a problem with your land — it's information about it.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Your land is one point inside Hoonah-Angoon Census Area
Everything above resolves to Hoonah-Angoon Census Area as a whole — one PHZM band and one county frost record, read across 4.2M acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at county scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better county average.

How we know this about Hoonah-Angoon Census Area
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Hoonah-Angoon Census Area carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Hoonah-Angoon Census Area
When does frost risk typically end in Hoonah-Angoon Census Area?
The last hard freeze (28°F) in Hoonah-Angoon Census Area typically lands around Mar 26, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Apr 16.
How long is the growing season in Hoonah-Angoon Census Area?
Measured between 28°F hard freezes, Hoonah-Angoon Census Area sees about 237 frost-free days — roughly Mar 26 through Nov 18, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 16 to Nov 4, about 202 days.
Is the soil safe to grow vegetables in Hoonah-Angoon Census Area?
The federal record around Hoonah-Angoon Census Area runs heavier than most — 304 documented sites, mostly Mining entries (285), the nearest PFAS record about 2.8 miles out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
Everything above is measured at Hoonah-Angoon Census Area's scale — its 4b-8a band and its 237-day season. Your yard writes its own version of Hoonah-Angoon Census Area's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
