Cedar City, Utah, sits in USDA hardiness zones 7a-8b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Crops well matched to these conditions include cherry, peach, tomato, and sego lily — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Cedar City, 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 Cedar City lot. Enter your address and we'll score 1,112 plants against your land's actual soil, sun, and frost.

Is it too late to plant in Cedar City?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 1 — long-season crops need about 90 days of runway, quick greens only 30. Here the season winds down slowly: late sowings, a real autumn harvest, and garlic in the ground before the first hard freeze.

Growing Challenges in Utah
What an experienced grower plans around here — each one has a move.

Very low rainfall — irrigation essential
Design the drip system before the beds — with mulch over it, high-desert ground grows on a fraction of the water you'd guess.

Alkaline soils (pH 7.5-8.5) limit many species
A soil test pins your actual pH — adapted species take the ground, acid-lovers take containers, nothing is off the table.

High altitude frost risk in mountain valleys
Mountain valleys trade on frost dates, not zone — know your real window and keep row covers close in the shoulder weeks.

A note from Gnorman
What an experienced grower watches for around here
In and around Cedar City, two things run higher than the national average — Toxic Release Inventory (18 sites) and Nitrate (64 sites). That's not a problem with your land — it's information about it.
Toxic Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Frequently Asked Questions
What hardiness zone is Cedar City, Utah?
Cedar City sits in USDA hardiness zones 7a-8b, 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 Cedar City?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 1 — long-season crops need about 90 days of runway, quick greens only 30. Here the season winds down slowly: late sowings, a real autumn harvest, and garlic in the ground before the first hard freeze.
When does frost risk typically end in Cedar City?
The last hard freeze (28°F) in Cedar City typically lands around Apr 5, 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 Cedar City?
The first hard freeze (28°F) in Cedar City typically arrives around Nov 1, 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 Cedar City?
Cedar City's zones 7a-8b support a wide range — strong performers include Cherry, Peach, Tomato, Sego Lily, and Blue Spruce. 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 Cedar City, really?
Officially, Cedar City sits in USDA zones 7a-8b (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 Cedar City?
The federal record around Cedar City is a meaningful one — 231 documented sites — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Cedar City?
As the season closes around the first 28°F hard freeze near Nov 1 (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.
