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 Mar 29; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 26 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 23 — long-season crops need about 90 days of runway, quick greens only 30. The tail of the season still works: sixty-day crops into late summer, quick greens after, garlic last of all.

Growing Challenges in Oregon

What an experienced grower plans around here — each one has a move.

West side: excessive rain and overcast skies reduce sun for warm-season crops

Map your sun honestly — a south-facing bed against a light wall recovers a surprising amount of the light the clouds take.

East side: arid conditions (8-15 inches rainfall) require irrigation

East of the Cascades, drip irrigation is infrastructure, not an accessory — plan it before the first planting.

Slug pressure is extreme in western Oregon

Evening patrols, iron-phosphate baits, and dry mulch edges knock slugs back — your extension guide covers the full toolkit.

Mountain areas have very short seasons (60-90 frost-free days)

At 60-90 frost-free days, season extension is the difference between a garden and a gamble — a high tunnel changes the math.

Frequently Asked Questions

What hardiness zone is Redmond, Oregon?

Redmond sits in USDA hardiness zones 4a-5b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.

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 Mar 29; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 26 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 23 — long-season crops need about 90 days of runway, quick greens only 30. The tail of the season still works: sixty-day crops into late summer, quick greens after, garlic last of all.

When does frost risk typically end in Redmond?

The last hard freeze (28°F) in Redmond typically lands around Apr 26, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.

When is the first frost in Redmond?

The first hard freeze (28°F) in Redmond typically arrives around Oct 23, per NOAA 1991–2020 climate normals — the point most tender summer crops finish. Lighter frosts usually reach a couple of weeks earlier, so watch the forecast from late summer on and harvest or cover tender plants before the first cold night.

What vegetables grow in Redmond?

Redmond's zones 4a-5b support a wide range — strong performers include Hazelnut, Blueberry, Kale, Hop, and Douglas Fir. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.

Which hardiness zone is Redmond, really?

Officially, Redmond sits in USDA zones 4a-5b (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.

Is the soil safe to grow vegetables in Redmond?

The federal record around Redmond shows 173 documented sites — 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 Redmond?

As the season closes around the first 28°F hard freeze near Oct 23 (NOAA 1991–2020 climate normals), a few moves buy time: cover tender plants with floating row cover or an old sheet on still, clear nights, water the soil the afternoon before a freeze so it holds warmth overnight, and harvest frost-tender crops like tomatoes, peppers, and basil before the first hard night. Hardy greens and root crops shrug off light frost and often sweeten after it, so leave them in.
