Hansville, Washington, sits in USDA hardiness zone 8b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
A short list that earns its place here — cabbage, fig, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Hansville, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Hansville lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Hansville
Each reading below is measured for Hansville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsHansville runs about 285 days between hard freezes (read from Kitsap County, the closest normal to Hansville) — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredHansville sits in USDA hardiness zone 8b.
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.

The kind of country Hansville is in
Hansville sits in the Puget Lowland — EPA Level III, inside the wider Marine West Coast Forest. That is read at Hansville's own centroid rather than borrowed from Kitsap County.

Is it too late to plant in Hansville?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 18; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 15 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 27 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

A note from Gnorman
What an experienced grower watches for around here
In and around Hansville, Nitrate runs higher than the national average — 54 sites within ~10 miles of Hansville. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Hansville
Everything above resolves to Hansville as a whole — one PHZM band, read across 7K acres, with hard-freeze dates borrowed from Kitsap County’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 Hansville
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 Kitsap County’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 Hansville
When does frost risk typically end in Hansville?
The last hard freeze (28°F) in Hansville typically lands around Feb 15, 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 Mar 8.
When is the first frost in Hansville?
The first hard freeze (28°F) in Hansville typically arrives around Nov 27, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 13, so the watching starts about Oct 28 — about 285 days after the spring freeze cleared.
How long is the growing season in Hansville?
Measured between 28°F hard freezes, Hansville sees about 285 frost-free days — roughly Feb 15 through Nov 27, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 8 to Nov 13, about 250 days.
Is the soil safe to grow vegetables in Hansville?
The federal record around Hansville shows 132 documented sites, mostly Underground Storage Tanks entries (65), the nearest Underground Storage Tanks record about 1.1 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Hansville?
From about Oct 28 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Nov 27 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Nov 27. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
