Midvale, Utah, sits in USDA hardiness zones 6a-7b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Expect cherry, peach, tomato, and sego lily to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Midvale, 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 Midvale lot. Enter your address and we'll score 1,112 plants against your land's actual soil, sun, and frost.

What Grows in Midvale
Plants matched to Midvale's USDA zones 6a-7b — each links to its full growing profile.
Is it too late to plant in Midvale?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Feb 10; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 10 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 12 — 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.

Frequently Asked Questions
What hardiness zone is Midvale, Utah?
Midvale 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 Midvale?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Feb 10; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 10 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 12 — 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 Midvale?
The last hard freeze (28°F) in Midvale typically lands around Mar 10, 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 Midvale?
The first hard freeze (28°F) in Midvale typically arrives around Nov 12, 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 Midvale?
Midvale's zones 6a-7b 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 Midvale, really?
Officially, Midvale 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 Midvale?
The federal record around Midvale runs heavier than most — 3,450 documented sites — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
How do I protect my plants from frost in Midvale?
As the season closes around the first 28°F hard freeze near Nov 12 (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.
