Planting zones in Shreveport-Bossier City, LA
Every ZIP code in this metro is USDA zone 8b. That is unusual — most metros span several zones — and it means the one number people usually look up is the same wherever you are here.

The growing season in Shreveport-Bossier City, LA is closing
Nothing in the 32-crop table still has time to mature here. The first fall freeze normally arrives November 11 – November 24 across the 10 NOAA stations serving this metro area .
Your next season already has a date
The first job of it is 🧅 Green Onions, start indoors, around January 3 – January 22 — counted back from a last spring freeze of February 28 – March 19 here.
These are ranges across the whole metro area. The ZIP lookup above gives the dates from your own nearest station instead.
All 10 stations agreeAt least one station
Every one of the 10 NOAA stations serving this metro area counts March 19 – November 11 as growing season (237 days). Widening to any single station gives February 28 – November 24 (269 days).
That is a 32-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.
Your freeze dates
Those are the earliest and latest medians among the 10 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 10 stations serving Shreveport-Bossier City, LA it runs 237–268 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 91–94 °F , at or above the 90 °F point where cool-season crops bolt and tomato and pepper pollen fails — so midsummer sowings of lettuce and its relatives are worth holding here. Summer rain over the same months runs 10.3–12.0" across those 10 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 85% 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 93 °F summer afternoon drying the soil faster than a cool one.
When to start seeds in Shreveport-Bossier City, LA
Every spring job for 63 crop dates, counted from this metro's own last spring freeze. Each is a range across all 10 stations — the earliest and latest that job falls anywhere in the metro — because no one station speaks for the whole area.

What lives through a zone 8b winter
Winter hardiness runs on the zone alone, so this one is exact for the whole of Shreveport-Bossier City, LA rather than a range. Of 74 perennial fruits, nuts, berries, vegetables and herbs, 54 come through a zone 8b winter — and 11 of the failures are not about cold at all, but about winters too mild to break dormancy or summers too hot.
Among them: Apple, Aronia, Elderberry, Asparagus, Horseradish, Sunchoke, Walking Onion, Chives. See the full list with reasons.
Cautious — shortens the seasonMedian across stationsOptimistic
- Last spring freeze
- Plan to April 6 to be careful. Median February 28 – March 19 across 10 stations; February 4 is the optimistic end.
- First fall freeze
- Plan to October 28 to be careful. Median November 11 – November 24 across 10 stations; December 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 10 stations behind these numbers
All 10 NOAA stations whose normals this page quotes, spanning about 117 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.

| Atlanta, TX | USC00410408 | March 19 | November 11 | 237 days |

| Shreveport, LA | USW00013957 | March 9 | November 18 | 255 days |
These are medians, not averages — NOAA publishes freeze dates as a probability distribution, and half of years freeze later than the date shown.

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.

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.
- Shade clothSummer highs here average 93 °F, at or above the 90 °F point where lettuce and spinach bolt and tomato pollen fails.
- 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.
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.
