Your ZIP code

Get the exact answer for your address

Everything above describes Hickory-Lenoir-Morganton, NC 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.

The growing season in Hickory-Lenoir-Morganton, NC is closing

Nothing in the 32-crop table still has time to mature here. The first fall freeze normally arrives October 13 – November 8 across the 7 NOAA stations serving this metro area .

Your next season already has a date

These are ranges across the whole metro area. The ZIP lookup above gives the dates from your own nearest station instead.

Growing season across Hickory-Lenoir-Morganton, NC A one-year bar. Every one of the 7 NOAA stations serving this metro area counts May 5 to October 13 as growing season, 161 days. At least one counts March 24 to November 8, 229 days. The same figures are written out below this chart. JFMAMJJASONDMay 5October 13

All 7 stations agreeAt least one station

Every one of the 7 NOAA stations serving this metro area counts May 5 – October 13 as growing season (161 days). Widening to any single station gives March 24 – November 8 (229 days).

That is a 68-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

Hickory-Lenoir-Morganton, NC covers 3 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 72% in zone 8a and wrong for the other 28%. Here is the actual split.

Zone ZIP codes Share  
8a 18 72%
7b 6 24%
6b 1 4%

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 March 24 – May 5
First fall freeze October 13 – November 8

Those are the earliest and latest medians among the 7 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 7 stations serving Hickory-Lenoir-Morganton, NC it runs 160–230 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 70–87 Β°F , below the 90 Β°F point where cool-season crops reliably bolt. Summer rain over the same months runs 13.1–18.3" across those 7 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 Hickory-Lenoir-Morganton, NC 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 86 Β°F summer afternoon drying the soil faster than a cool one.

When to start seeds in Hickory-Lenoir-Morganton, NC

Every spring job for 63 crop dates, counted from this metro's own last spring freeze. Each is a range across all 7 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 Hickory-Lenoir-Morganton, NC

Of 74 perennial fruits, nuts, berries, vegetables and herbs, 57 come through the winter in zone 8a and only 51 in zone 6b. That is a different garden at each end of the same metro.

Zone ZIPs Survive Fail for being too warm
6b 1 51 of 74 0
7b 6 56 of 74 3
8a 18 57 of 74 8

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.

How certain the freeze dates are in Hickory-Lenoir-Morganton, NC 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 May 20 to be careful. Median March 24 – May 5 across 7 stations; March 5 is the optimistic end.
First fall freeze
Plan to September 27 to be careful. Median October 13 – November 8 across 7 stations; November 26 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 7 stations behind these numbers

The 7 NOAA stations serving Hickory-Lenoir-Morganton, NC A relative sketch of where the stations sit, about 50 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.

All 7 NOAA stations whose normals this page quotes, spanning about 50 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.

These are medians, not averages β€” 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.

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.
