Tazlina, Alaska, sits in USDA hardiness zone 2b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
These conditions suit cabbage, potato, rhubarb, and kale — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Tazlina, no two yards are alike.

What this means for growing in Tazlina
Each reading below is measured for Tazlina itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsTazlina runs about 109 days between hard freezes (read from Copper River Census Area, the closest normal to Tazlina) — a short growing season.
Long-maturing crops like melons, sweet potatoes, and winter squash can run out of runway before the first hard freeze, ripening late or not at all.
Lead with fast-maturing varieties, and stretch the season on both ends with cold frames, low tunnels, or a greenhouse.

Winter hardiness
MeasuredTazlina sits in USDA hardiness zone 2b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

What Grows in Tazlina
Plants matched to Tazlina's USDA zones 2b, ordered by how much hardiness margin each has here — the ones with room to spare at both ends of this town's band lead. Each links to its full growing profile.
Is it too late to plant in Tazlina?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Apr 23; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 21 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 7 — long-season crops need about 90 days of runway, quick greens only 30. When the window is tight, the fall moves are quick ones — baby greens, radishes, and garlic set for next season.

What an experienced grower watches for around here
In and around Tazlina, two things run higher than the national average within ~10 miles of Tazlina — Nitrate (90 sites) and Superfund (3 sites). That's not a problem with your land — it's information about it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Tazlina
Everything above resolves to Tazlina as a whole — one PHZM band, read across 5K acres, with hard-freeze dates borrowed from Copper River Census Area’s record because no 30-year normal resolves at this town’s own centroid. 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 town 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 local average.

How we know this about Tazlina
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Copper River Census Area’s record, because none resolves here; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Tazlina
When does frost risk typically end in Tazlina?
The last hard freeze (28°F) in Tazlina typically lands around May 21, 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 Jun 11.
When is the first frost in Tazlina?
The first hard freeze (28°F) in Tazlina typically arrives around Sep 7, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Aug 24, so the watching starts about Aug 8 — about 109 days after the spring freeze cleared.
How long is the growing season in Tazlina?
Measured between 28°F hard freezes, Tazlina sees about 109 frost-free days — roughly May 21 through Sep 7, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 11 to Aug 24, about 74 days.
Is the soil safe to grow vegetables in Tazlina?
The federal record around Tazlina is a meaningful one — 114 documented sites, mostly Nitrate entries (90), the nearest Nitrate record about 0.8 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do gardeners stretch the season in Tazlina?
With about 109 frost-free days between hard freezes, Tazlina rewards the classic extension moves: floating row cover buys roughly two to four extra weeks at each shoulder — on this season that is a working window nearer 137 to 165 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 21 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Tazlina's scale — its 2b band and its 109-day season. Your yard writes its own version of Tazlina's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
