Planting zones in Augusta-Richmond County, GA-SC

This metro spans USDA zones 8a to 8b, so there is no single zone for Augusta-Richmond County, GA-SC and anyone who gives you one is rounding. 88% of its ZIP codes are zone 8b; the rest are not.

USDA zones 8a–8b 2 zones across 43 ZIP codes

Your ZIP code

Get the exact answer for your address

Everything above describes Augusta-Richmond County, GA-SC 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.

Augusta-Richmond County, GA-SC does not have one planting answer

Its own weather stations disagree about 22 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
206 days
GRANITEVILLE 1.2 NE, SC US (USC00383665)
Longest season

AUGUSTA DANIEL FLD AP, GA US (USW00013837)

77 days of growing season separate those two stations, and both serve ZIP codes in Augusta-Richmond County, GA-SC. 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 Augusta-Richmond County, GA-SC A one-year bar. Every one of the 15 NOAA stations serving this metro area counts April 9 to November 1 as growing season, 206 days. At least one counts February 27 to December 4, 280 days. The same figures are written out below this chart. JFMAMJJASONDApril 9November 1

All 15 stations agreeAt least one station

Every one of the 15 NOAA stations serving this metro area counts April 9 – November 1 as growing season (206 days). Widening to any single station gives February 27 – December 4 (280 days).

That is a 74-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.

Which zone you are in depends where you are

Augusta-Richmond County, GA-SC covers 2 hardiness zones. A guide that gives the metro one zone has picked whichever is largest and rounded everyone else into it β€” which is fine for the 88% in zone 8b and wrong for the other 12%. Here is the actual split.

Zone ZIP codes Share  
8b 38 88%
8a 5 12%

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

Last spring freeze February 27 – April 9
First fall freeze November 1 – December 4

Those are the earliest and latest medians among the 15 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 15 stations serving Augusta-Richmond County, GA-SC it runs 206–283 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 89–93 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 13.6–16.1" 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 Augusta-Richmond County, GA-SC 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 Augusta-Richmond County, GA-SC

Every spring job for 63 crop dates, counted from this metro's own last spring freeze. Each is a range across all 15 stations β€” the earliest and latest that job falls anywhere in the metro β€” because no one station speaks for the whole area.

What survives the winter changes across Augusta-Richmond County, GA-SC

Of 74 perennial fruits, nuts, berries, vegetables and herbs, 57 come through the winter in zone 8a and only 54 in zone 8b. That is a different garden at each end of the same metro.

Zone ZIPs Survive Fail for being too warm
8a 5 57 of 74 8
8b 38 54 of 74 11

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 Β°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.

At least one station here freezes across the new year, which puts the two ends of a spread on opposite sides of the calendar. Drawing it would produce a bar spanning almost the whole year and meaning nothing, so none is drawn.

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.

Each of these takes a ZIP code and answers for that ZIP alone, citing the station it used and how far away it is. There is a ZIP box in the header of every page.

Other places to compare

These metros span exactly the same zones β€” 8a–8b β€” so the same plants are in and out of range across them. The freeze dates and the spring calendar are their own.

Gardening in Georgia β€” zones 7b– 9a covers the whole state: how its 743 ZIP codes divide between 4 hardiness zones, and the freeze dates across every NOAA station 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.
