Planting zones in Traverse City, MI
This metro spans USDA zones 5a to 6b, so there is no single zone for Traverse City, MI and anyone who gives you one is rounding. 48% of its ZIP codes are zone 6b; the rest are not.

Everything above describes Traverse City, MI as a whole. Hardiness zones and freeze dates are published per ZIP code, so yours is exact — enter it and this page will tell you your zone, which NOAA station it comes from and how far away that station is.
The growing season in Traverse City, MI is closing
Nothing in the 32-crop table still has time to mature here. The first fall freeze normally arrives September 22 – November 1 across the 12 NOAA stations serving this metro area .
Your next season already has a date
The first job of it is 🧅 Green Onions, start indoors, around March 5 – April 1 — counted back from a last spring freeze of April 30 – May 27 here.
These are ranges across the whole metro area. The ZIP lookup above gives the dates from your own nearest station instead.
All 12 stations agreeAt least one station
Every one of the 12 NOAA stations serving this metro area counts May 27 – September 22 as growing season (118 days). Widening to any single station gives April 30 – November 1 (185 days).
That is a 67-day difference inside one metro area — which is why this page gives ranges rather than a single planting date. The ZIP lookup above resolves it to one station.
Which zone you are in depends where you are
Traverse City, MI covers 4 hardiness zones. A guide that gives the metro one zone has picked whichever is largest and rounded everyone else into it — which is fine for the 48% in zone 6b and wrong for the other 52%. Here is the actual split.
| Zone | ZIP codes | Share | |
|---|---|---|---|
| 6b | 14 | 48% | |
| 6a | 9 | 31% | |
| 5b | 5 | 17% | |
| 5a | 1 | 3% |
Zones are published per ZIP code, so yours is exact even though the metro's is not. The hardiness tool will tell you which one you are in.
Your freeze dates
Those are the earliest and latest medians among the 12 stations serving this metro — not an average, and not one station standing in for the rest. Half of years freeze later than a station's own median.
The spread is the point. Even in a metro that is one hardiness zone throughout, its stations disagree about the last spring freeze. Hardiness zone and frost date measure different things — a zone is the average annual coldest night, a freeze date is when the season turns — and a place can be uniform in one and varied in the other. Use the tools below with your own ZIP rather than the ends of this range.
Your growing season
NOAA publishes a growing-season length for each station, and across the 12 stations serving Traverse City, MI it runs 117–182 days . That figure is published, not computed from the two freeze dates — subtracting one from the other gives the wrong answer wherever a season crosses New Year. Mean summer high (June–August) runs 74–79 °F , below the 90 °F point where cool-season crops reliably bolt. Summer rain over the same months runs 8.3–10.4" across those 11 stations, against the rough inch a week — about 13 inches over the same 92 days — that a vegetable garden is usually reckoned to want. The middle station covers about 69% of it, so expect to make up the rest. The inches are NOAA's published normals; the inch a week is a rule of thumb, and it takes no account of a 77 °F summer afternoon drying the soil faster than a cool one.
When to start seeds in Traverse City, MI
Every spring job for 63 crop dates, counted from this metro's own last spring freeze. Each is a range across all 12 stations — the earliest and latest that job falls anywhere in the metro — because no one station speaks for the whole area.

What survives the winter changes across Traverse City, MI
Of 74 perennial fruits, nuts, berries, vegetables and herbs, 51 come through the winter in zone 6a and only 48 in zone 5a. That is a different garden at each end of the same metro.
| Zone | ZIPs | Survive | Fail for being too warm |
|---|---|---|---|
| 5a | 1 | 48 of 74 | 0 |
| 5b | 5 | 48 of 74 | 0 |
| 6a | 9 | 51 of 74 | 0 |
| 6b | 14 | 51 of 74 | 0 |
The last column is the counterintuitive one, and it is why the totals do not simply rise as the winters get milder. Most temperate fruit needs a documented number of hours below about 45 °F to break dormancy and set a crop, so an apple fails in a winter that is too warm; currants and rhubarb cook in the summer heat that comes with it. See the full list with reasons.
Cautious — shortens the seasonMedian across stationsOptimistic
- Last spring freeze
- Plan to June 13 to be careful. Median April 30 – May 27 across 12 stations; April 16 is the optimistic end.
- First fall freeze
- Plan to September 4 to be careful. Median September 22 – November 1 across 12 stations; November 14 is the optimistic end.
NOAA publishes these as probabilities, not averages — the middle figure is a median, so half of years fall either side of it. The cautious end is the 10% tail: in roughly nine years in ten the freeze falls on the safe side of it.
The 12 stations behind these numbers
All 12 NOAA stations whose normals this page quotes, spanning about 67 km north to south. Every one is named with its identifier in the station list below — this page does not single one out, because no one station speaks for a whole metro area.
A relative sketch, not a map with a projection: longitude is adjusted for latitude so the shape is not stretched, and there is no basemap. For the one station nearest a specific address, with its real distance, use the ZIP lookup above.
Every figure above comes from these, and each is named so you can check it. Which station serves a given ZIP code, and how far away it is, varies across the metro — the table below gives it per ZIP code rather than this page averaging it.

These are medians, not averages — NOAA publishes freeze dates as a probability distribution, and half of years freeze later than the date shown.
Every ZIP code in Traverse City, MI
Zones are published per ZIP code, not per metro area, so this is the exact answer rather than the metro area's average. The station column is the nearest one to that ZIP code's centroid and how far away it is — the same figure the tools use, shown here so you can see which ZIP codes are well covered and which are reaching.

What survives my winter?
Runs on the hardiness zone, so it answers for all of Traverse City, MI at once — zone across 74 perennial fruits, berries, vegetables and herbs.
- When do I start my seeds?
Dates every spring job from your own last freeze — sow indoors, set out, direct sow.
- When do I sow the next round?

If you want to act on this
Each link opens an Amazon search rather than a product we picked. We have not tested these and do not rank them — the search is the honest version, and you choose.
- Trunk wrapZone 5a is cold enough that winter sun on a young trunk does more damage than the cold does.
- Row cover and frost clothThe season here closes at the first fall freeze dated above — a cover buys back some of those days at the end.
- MulchFor the perennials nearest their cold limit in zone 5a, where an insulated crown is what decides whether they come back.
As an Amazon Associate we earn from qualifying purchases. That costs you nothing extra, and it buys no influence over anything on this site: the dates come from NOAA normals and the zones from the USDA, and no product affects either.

Where these numbers come from
The hardiness zone is the USDA 2023 Plant Hardiness Zone Map, published per ZIP code by PRISM at Oregon State. The freeze dates are NOAA's 1991–2020 Climate Normals, read from every station whose normals cover a ZIP code in this metro. Nothing here is estimated, and no station stands in for another.
This page names no single station on purpose. Picking one to represent a metro sounds reasonable and is not: the station serving the most ZIP codes is an artifact of where ZIP centroids happen to fall, and it selects a lock on the Monongahela for Pittsburgh and a far southern suburb for Chicago. A range across every station is true; a single cited date for a whole metro is not.
