Planting zones in Pope County, Arkansas

This county spans USDA zones 7b to 8a, so there is no single zone for Pope County and anyone who gives you one is rounding. 63% of its ZIP codes are zone 8a; the rest are not.

USDA zones 7b–8a 2 zones across 8 ZIP codes

Weather stations 5 NOAA 1991–2020 normals, across 811 sq mi

Your ZIP code

Get the exact answer for your address

Everything above describes Pope County, Arkansas 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.

Pope County does not have one planting answer

Its own weather stations disagree about 12 of the 32 crops in this table right now, so any single list would be wrong for part of the county. That is not a gap in the data β€” it is what the data says.

Shortest season
212 days
DENNARD 10 WSW, AR US (USC00031935)
Longest season
232 days
CLARKSVILLE 6 NE, AR US (USC00031457)

20 days of growing season separate those two stations, and both serve ZIP codes in Pope County. 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 Pope County A one-year bar. Every one of the 5 NOAA stations serving this county counts April 4 to November 2 as growing season, 212 days. At least one counts March 25 to November 10, 230 days. The same figures are written out below this chart. JFMAMJJASONDApril 4November 2

All 5 stations agreeAt least one station

Every one of the 5 NOAA stations serving this county counts April 4 – November 2 as growing season (212 days). Widening to any single station gives March 25 – November 10 (230 days).

Which zone you are in depends where you are

Pope County covers 2 hardiness zones. A guide that gives the county one zone has picked whichever is largest and rounded everyone else into it β€” fine for the 63% in zone 8a and wrong for the other 37%. Here is the actual split.

Zone ZIP codes Share  
8a 5 63%
7b 3 38%

Zones are published per ZIP code, so yours is exact even though the county's is not. The hardiness tool will tell you which one you are in.

Your freeze dates

Last spring freeze March 25 – April 4
First fall freeze November 2 – November 10

Across the 5 NOAA stations serving this county. These are medians β€” half of years freeze later than the date shown β€” so treat the later end of each range as the cautious one.

The growing season runs 212–232 days depending which station you are nearest, as published by NOAA rather than computed from the dates above. Summer highs average 85.2–91.8 Β°F in June–August. That is past the point where tomato and pepper pollen fails and cool-season greens bolt, so in this county heat decides as much as frost does. Summer rain over the same months runs 10.3–13.3" across those 5 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. The middle station covers about 84% 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 91 Β°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 β€” 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
72686 7b Dennard 10 Wsw, AR 27.6 km
72801 8a Russellville Muni AP, AR 5.0 km
72802 8a Russellville Muni AP, AR 6.9 km

72847 8a Dardanelle, AR 17.7 km
72858 8a Russellville Muni AP, AR 7.0 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.

What survives the winter changes across Pope County

Zone 8a carries 57 of 74 perennial edibles; zone 7b carries 56. The best number is not always the warmest zone β€” the count peaks in the middle and falls both ways, because the warm end loses plants to insufficient winter chill and summer heat, not to cold.

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 β€” a coastal zone 8 and an inland zone 8 are not the same summer.

How certain the freeze dates are in Pope County 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 20 to be careful. Median March 25 – April 4 across 5 stations; March 6 is the optimistic end.
First fall freeze
Plan to October 19 to be careful. Median November 2 – November 10 across 5 stations; November 30 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 5 stations behind these numbers

The 5 NOAA stations serving Pope County A relative sketch of where the stations sit, about 63 kilometres north to south. Each is named with its NOAA identifier in the station list on this page, which carries the same information as text. CLARKSVILLE 6 NE, AR US (USC00031457)DARDANELLE, AR US (USC00031838)DENNARD 10 WSW, AR US (USC00031935)MORRILTON, AR US (USC00034938)RUSSELLVILLE MUNI AP, AR US (USW00053920) ~63 km north to south

All 5 NOAA stations whose normals this page quotes, spanning about 63 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 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 β€” 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.

These are medians, not averages β€” NOAA publishes freeze dates as a probability distribution, and half of years freeze later than the date shown.

Each link opens an Amazon search rather than a product we picked. We have not tested these and do not rank them β€” the search is the honest version, and you choose.

Sources

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 β€” 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.
