Clear Creek, California, sits in USDA hardiness zones 6a-7b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
The conditions favor tomato, grape, fig, and california poppy, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Clear Creek, no two yards are alike.

What Grows in Clear Creek
Plants matched to Clear Creek's USDA zones 6a-7b — each links to its full growing profile.
Is it too late to plant in Clear Creek?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Mar 27; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 24 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 7 — 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 California
What an experienced grower plans around here — each one has a move.
Drought is a persistent challenge — irrigation is essential in most regions
Design the water system before the plants: drip lines plus a thick mulch layer run a full garden on surprisingly little water.
Wildfire risk affects rural and foothill properties
Keep plantings low, lean, and well-watered near structures — your extension office publishes firewise landscaping guides for your county.
Adobe clay soils in valleys drain poorly without amendment
Work in compost over seasons, or skip the fight with a raised bed — adobe's nutrients are excellent once drainage is solved.
Wide climate variation means plant selection is highly location-specific
Zones run 5a to 11a in one state — check your exact zone before trusting any statewide planting list.

In and around Clear Creek, Brownfields runs higher than the national average — 40 sites nearby. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

Frequently Asked Questions
What hardiness zone is Clear Creek, California?
Clear Creek sits in USDA hardiness zones 6a-7b, 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 Clear Creek?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Mar 27; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 24 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 7 — 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 Clear Creek?
The last hard freeze (28°F) in Clear Creek typically lands around Apr 24, 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 Clear Creek?
The first hard freeze (28°F) in Clear Creek typically arrives around Nov 7, 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 Clear Creek?
Clear Creek's zones 6a-7b support a wide range — strong performers include Tomato, Grape, Fig, California Poppy, and Almond. 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 Clear Creek, really?
Officially, Clear Creek sits in USDA zones 6a-7b (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 Clear Creek?
The federal record around Clear Creek shows 59 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 Clear Creek?
As the season closes around the first 28°F hard freeze near Nov 7 (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.
