Is it too late to plant in Clawson?
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 14; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 11 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 26 — 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 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.
For cultivar selection, pest pressure, and planting-time guidance specific to Utah, the Utah State University Extension is the authoritative local source.

What an experienced grower watches for around here
In and around Clawson, Underground Storage Tanks runs higher than the national average — 24 sites nearby. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Frequently Asked Questions
What hardiness zone is Clawson, Utah?
Clawson 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 Clawson?
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 14; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 11 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 26 — 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 Clawson?
The last hard freeze (28°F) in Clawson typically lands around Apr 11, 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 Clawson?
The first hard freeze (28°F) in Clawson typically arrives around Oct 26, 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 Clawson?
Clawson'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 Clawson, really?
Officially, Clawson 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 Clawson?
The federal record around Clawson is light — 30 documented sites across the 9 federal source types we checked — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do I protect my plants from frost in Clawson?
As the season closes around the first 28°F hard freeze near Oct 26 (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.
