Planting zones in Pope County, Minnesota
Every ZIP code in this county is USDA zone 4b — so unlike most of the places people look up, there is one right answer here and it holds wherever you are in the county.
Your ZIP code

Everything above describes Pope County, Minnesota 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 Pope County is closing
Nothing in the 32-crop table still has time to mature here. The first fall freeze normally arrives September 27 – October 4 across the 4 NOAA stations serving this county .
Your next season already has a date
The first job of it is 🧅 Green Onions, start indoors, around March 9 – March 16 — counted back from a last spring freeze of May 4 – May 11 here.
These are ranges across the whole county. The ZIP lookup above gives the dates from your own nearest station instead.
All 4 stations agreeAt least one station
Every one of the 4 NOAA stations serving this county counts May 11 – September 27 as growing season (139 days). Widening to any single station gives May 4 – October 4 (153 days).
Your freeze dates
Across the 4 NOAA stations serving this county. These are medians — half of years freeze later than the date shown — so treat the later end of each range as the cautious one.
The growing season runs 139–152 days depending which station you are nearest, as published by NOAA rather than computed from the dates above. Summer highs average 78.9–81.1 °F in June–August. Summer rain over the same months runs 11.9–12.6" across those 4 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 93% 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 81 °F summer afternoon drying the soil faster than a cool one.
Every ZIP code in Pope County
Zones are published per ZIP code, not per county, so this is the exact answer rather than the county'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.
| ZIP code | USDA zone | Nearest NOAA station | Distance |
|---|---|---|---|
| 56226 | 4b | Benson, MN | 11.2 km |
| 56316 | 4b | New London, MN | 27.4 km |
| 56323 | 4b | Morris W Cntrl Rsch & Outreach, MN | 12.5 km |
| 56327 | 4b | Glenwood 2Wnw, MN | 16.9 km |
| 56334 | 4b | Glenwood 2Wnw, MN | 12.3 km |
| 56349 | 4b | Glenwood 2Wnw, MN | 9.2 km |
| 56381 | 4b | Glenwood 2Wnw, MN | 13.6 km |
| 56385 | 4b | Glenwood 2Wnw, MN | 17.9 km |
ZIP-code positions are area centroids, so a large rural ZIP code's listed distance is measured from the middle of its area rather than from any particular address in it.

Offsets are published guidance; the dates they land on are computed from measured NOAA normals. The seed-starting tool does this for your own ZIP code and counts the days.
What lives through a zone 4b winter
Of 74 perennial edibles, 34 come through a zone 4b winter — and 0 fail here for being too warm rather than too cold, needing more winter chill than this county gets or more heat than they tolerate. Among the ones that work: Cranberry, Honeyberry, Lingonberry, Apple, Aronia, Black Currant, Elderberry, Gooseberry.
Hardiness ranges are a judgement, published by growers rather than measured; the zone they are compared against is measured. On a warm-end verdict, check with your local extension service — a coastal zone 8 and an inland zone 8 are not the same summer.
Cautious — shortens the seasonMedian across stationsOptimistic
- Last spring freeze
- Plan to May 27 to be careful. Median May 4 – May 11 across 4 stations; April 21 is the optimistic end.
- First fall freeze
- Plan to September 13 to be careful. Median September 27 – October 4 across 4 stations; October 17 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 4 stations behind these numbers
All 4 NOAA stations whose normals this page quotes, spanning about 39 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 county.
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.
These are the stations this county's ZIP codes actually cite as nearest — not a claim that each one sits inside its boundary, since a rural ZIP legitimately reaches over it. Every figure above comes from them, and each is named so you can check it.
| Station | NOAA ID | Last spring freeze | First fall freeze | Season |
|---|---|---|---|---|
| Benson, MN | USC00210667 | May 4 | October 3 | 151 days |
| Glenwood 2Wnw, MN | USC00213174 | May 11 | September 27 | 139 days |
| Morris W Cntrl Rsch & Outreach, MN | USC00215638 | May 4 | October 1 | 150 days |
| New London, MN | USC00215842 | May 4 | October 4 | 152 days |
These are medians, not averages — NOAA publishes freeze dates as a probability distribution, and half of years freeze later than the date shown.

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 4b 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 4b, 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
Hardiness zones are the USDA 2023 Plant Hardiness Zone Map, published per ZIP code by PRISM at Oregon State. Freeze dates and growing-season lengths are NOAA 1991–2020 Climate Normals, taken per station and cited above by name and NOAA ID.
County boundaries come from the Census ZCTA-to-county relation, which is what places each ZIP code — and which treats parishes, boroughs and census areas as county equivalents. No station is chosen to represent this county: every range above is taken across all of them and the count is stated, because picking one would be a judgement dressed as a measurement.
