Planting zones in Montgomery, AL

Every ZIP code in this metro is USDA zone 8b. That is unusual β€” most metros span several zones β€” and it means the one number people usually look up is the same wherever you are here.

Your ZIP code

Get the exact answer for your address

Everything above describes Montgomery, AL as a whole. Hardiness zones and freeze dates are published per ZIP code, so yours is exact β€” enter it and this page will tell you your zone, which NOAA station it comes from and how far away that station is.

Works for all 40,502 US ZIP codes. Freeze dates need a NOAA station within 100 km; where there is none, the page says so rather than estimating one.

Montgomery, AL does not have one planting answer

Its own weather stations disagree about 15 of the 32 crops in this table right now, so any single list would be wrong for part of the metro area. That is not a gap in the data β€” it is what the data says.

Shortest season
220 days
HIGHLAND HOME, AL US (USC00013816)
Longest season
262 days
MONTGOMERY 6SW, AL US (USC00015553)

42 days of growing season separate those two stations, and both serve ZIP codes in Montgomery, AL. The ZIP lookup above answers for one address instead of averaging a place that has no average.

Why the hardiness zone does not settle this

A USDA zone is a winter-minimum statistic. It was never a growing-season one, and it does not behave like one: within a single zone the growing season runs a median 54 days wider at the 10th–90th percentile, and annual growing degree days vary by 2.02Γ—.

The zones also overlap rather than stack β€” 30% of zone 6b freezes before the median zone 6a station. The zone tells you what survives your winter; the station tells you what finishes before your autumn.

The whole dataset behind that β†’

Growing season across Montgomery, AL A one-year bar. Every one of the 10 NOAA stations serving this metro area counts March 31 to November 5 as growing season, 219 days. At least one counts March 4 to November 20, 261 days. The same figures are written out below this chart. JFMAMJJASONDMarch 31November 5

All 10 stations agreeAt least one station

Every one of the 10 NOAA stations serving this metro area counts March 31 – November 5 as growing season (219 days). Widening to any single station gives March 4 – November 20 (261 days).

That is a 42-day difference inside one metro area β€” 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

Last spring freeze March 4 – March 31
First fall freeze November 5 – November 20

Those are the earliest and latest medians among the 10 stations serving this metro β€” 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 β€” a zone is the average annual coldest night, a freeze date is when the season turns β€” 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 Montgomery, AL it runs 220–262 days . That figure is published, not computed from the two freeze dates β€” subtracting one from the other gives the wrong answer wherever a season crosses New Year. Mean summer high (June–August) runs 87–93 Β°F , at or above the 90 Β°F point where cool-season crops bolt and tomato and pepper pollen fails β€” so midsummer sowings of lettuce and its relatives are worth holding here. Summer rain over the same months runs 12.8–16.2" across those 9 stations, against the rough inch a week β€” about 13 inches over the same 92 days β€” that a vegetable garden is usually reckoned to want. At the middle station that is covered, so watering in Montgomery, AL is for the gaps between storms rather than the whole season. The inches are NOAA's published normals; the inch a week is a rule of thumb, and it takes no account of a 91 Β°F summer afternoon drying the soil faster than a cool one.

When to start seeds in Montgomery, AL

Every spring job for 63 crop dates, counted from this metro's own last spring freeze. Each is a range across all 10 stations β€” the earliest and latest that job falls anywhere in the metro β€” 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 Montgomery, AL rather than a range. Of 74 perennial fruits, nuts, berries, vegetables and herbs, 54 come through a zone 8b winter β€” 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.

How certain the freeze dates are in Montgomery, AL Two rows. Each runs from the cautious date, which shortens the growing season, to the optimistic one. The median dates sit between them. Every figure is repeated in the text below this chart. JFMAMJJASONDLast spring freezeFirst fall freeze

Cautious β€” shortens the seasonMedian across stationsOptimistic

Last spring freeze
Plan to April 17 to be careful. Median March 4 – March 31 across 10 stations; February 9 is the optimistic end.
First fall freeze
Plan to October 24 to be careful. Median November 5 – November 20 across 10 stations; December 11 is the optimistic end.

NOAA publishes these as probabilities, not averages β€” 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 114 km north to south. Every one is named with its identifier in the station list below β€” 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 β€” the table below gives it per ZIP code rather than this page averaging it.

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.

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.
