Benzie County, in Michigan, sits in USDA hardiness zone 6b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
On paper, cabbage, blackberry, california poppy, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.

Heat in Benzie County
Across a year, Benzie County accumulates about 1,941 growing degree days above 50°F, about 159 fewer than the middle Michigan county — ahead of 34 of Michigan’s 83 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.

Soil in Benzie County
Across Benzie County, the ground is predominantly Spodosols, where Benzonia, Kaleva, and Benona are the most extensive named soil series. The soil is generally excessively drained with a sand surface. Topsoil pH runs about 4.5–5.7, strongly acidic. Rainfall drains through hydrologic group A soils.

How the ground varies across Benzie County
The USDA soil survey maps 29% of Benzie County as excessively drained — but another 62% drains differently: 24% well drained, 18% somewhat excessively drained.
Benzonia is the most extensive named soil at 21% of mapped acres, then Kaleva (20%) and Benona (8%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Benzie County
Each reading below is measured for Benzie County itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Drainage
MeasuredThe dominant soils across Benzie County are excessively drained, in hydrologic group A — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO

Surface pH
MeasuredTopsoil across Benzie County runs about pH 4.5–5.7, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO

Season length
MeasuredBenzie County runs about 194 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.
NOAA 1991–2020 Climate Normals

Winter hardiness
MeasuredBenzie County sits in USDA hardiness zone 6b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Benzie County is in
Benzie County sits in the North Central Hardwood Forests — EPA Level III, inside the wider Eastern Temperate Forests. One consistent ecological setting across the whole county.
What Grows in Benzie County
We scored all 1,086 plants against Benzie County's own USDA zone 6b and its own 194-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Michigan profile.






























Is it too late to plant in Benzie County?
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 31; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 28 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 8 — 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.

What the federal record shows across Benzie County — and how to grow with it.
We checked the federal record across Benzie County — 121 documented sites across 5 of the 9 source types we track.
The most significant on record: 2 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Benzie County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.

Your land is one point inside Benzie County
Everything above resolves to Benzie County as a whole — one PHZM band and one county frost record, read across 205K acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at county scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better county average.

How we know this about Benzie County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Benzie County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Benzie County
When does frost risk typically end in Benzie County?
The last hard freeze (28°F) in Benzie County typically lands around Apr 28, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about May 19.
How long is the growing season in Benzie County?
Measured between 28°F hard freezes, Benzie County sees about 194 frost-free days — roughly Apr 28 through Nov 8, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 19 to Oct 25, about 159 days.
Is the soil safe to grow vegetables in Benzie County?
The federal record around Benzie County is a meaningful one — 121 documented sites, mostly Underground Storage Tanks entries (73), the nearest Underground Storage Tanks record about 0.2 miles out — 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.
