Redmond, Oregon, sits in USDA hardiness zone 6b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
On paper, cabbage, blackberry, california poppy, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Redmond, 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 Redmond 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 Redmond
Each reading below is measured for Redmond itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredRedmond runs about 134 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.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredRedmond sits in USDA hardiness zone 6b.
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 Redmond is in
Redmond sits in the Blue Mountains — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Redmond's own centroid, and it is not what its county reads: Deschutes County is mostly Eastern Cascades Slopes and Foothills. The wider page above you is answering a different question about different ground.

Is it too late to plant in Redmond?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Apr 20; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 29 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Redmond, Toxics Release Inventory runs higher than the national average — 14 sites within ~10 miles of Redmond. That's not a problem with your land — it's information about it.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside Redmond
Everything above resolves to Redmond as a whole — one PHZM band and one 28°F frost record, read across 12K 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 city 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 Redmond
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Redmond’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 city grain anywhere on this page — there is no city-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 Redmond
When does frost risk typically end in Redmond?
The last hard freeze (28°F) in Redmond typically lands around May 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 Jun 8.
When is the first frost in Redmond?
The first hard freeze (28°F) in Redmond typically arrives around Sep 29, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 15, so the watching starts about Aug 30 — about 134 days after the spring freeze cleared.
How long is the growing season in Redmond?
Measured between 28°F hard freezes, Redmond sees about 134 frost-free days — roughly May 18 through Sep 29, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 8 to Sep 15, about 99 days.
Is the soil safe to grow vegetables in Redmond?
The federal record around Redmond shows 173 documented sites, mostly Underground Storage Tanks entries (91), the nearest Underground Storage Tanks record about 0.1 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 gardeners stretch the season in Redmond?
With about 134 frost-free days between hard freezes, Redmond 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 162 to 190 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 18 hard-freeze normal stretches the season without touching the calendar.
