Beaver Marsh, Oregon, sits in USDA hardiness zone 6a — 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 — pumpkin, blackberry, california poppy, and zucchini — with any one site's soil, sun, and drainage making the final cut.
Even in Beaver Marsh, 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 Beaver Marsh 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 Beaver Marsh
Each reading below is measured for Beaver Marsh itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredBeaver Marsh runs about 64 days between hard freezes — 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
MeasuredBeaver Marsh sits in USDA hardiness zone 6a.
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 Beaver Marsh is in
Beaver Marsh sits in the Eastern Cascades Slopes and Foothills — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Beaver Marsh's own centroid rather than borrowed from Klamath County.

Is it too late to plant in Beaver Marsh?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around May 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jun 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Aug 21 — long-season crops need about 90 days of runway, quick greens only 30. Even here the calendar’s edges hold value: thirty-day greens late in the window, then garlic and a rested bed for spring.

Your land is one point inside Beaver Marsh
Everything above resolves to Beaver Marsh as a whole — one PHZM band and one 28°F frost record, read across 209 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 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 Beaver Marsh
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 Beaver Marsh’s own record; 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 Beaver Marsh
When does frost risk typically end in Beaver Marsh?
The last hard freeze (28°F) in Beaver Marsh typically lands around Jun 18, 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 Jul 9.
When is the first frost in Beaver Marsh?
The first hard freeze (28°F) in Beaver Marsh typically arrives around Aug 21, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Aug 7, so the watching starts about Jul 22 — about 64 days after the spring freeze cleared.
How long is the growing season in Beaver Marsh?
Measured between 28°F hard freezes, Beaver Marsh sees about 64 frost-free days — roughly Jun 18 through Aug 21, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jul 9 to Aug 7, about 29 days.
Is the soil safe to grow vegetables in Beaver Marsh?
The federal record around Beaver Marsh is light — 24 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (21), the nearest Underground Storage Tanks record under a tenth of a mile out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do gardeners stretch the season in Beaver Marsh?
With about 64 frost-free days between hard freezes, Beaver Marsh 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 92 to 120 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the Jun 18 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Beaver Marsh's scale — its 6a band and its 64-day season. Your yard writes its own version of Beaver Marsh's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
