Chadbourn, North Carolina, sits in USDA hardiness zone 8b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Crops well matched to these conditions include cabbage, fig, california poppy, and collard greens — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Chadbourn, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Chadbourn lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Chadbourn
Each reading below is measured for Chadbourn itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsChadbourn runs about 270 days between hard freezes (read from Columbus County, the closest normal to Chadbourn) — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredChadbourn sits in USDA hardiness zone 8b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Chadbourn is in
Chadbourn sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Chadbourn's own centroid, and it is not what its county reads: Columbus County is mostly Middle Atlantic Coastal Plain. The wider page above you is answering a different question about different ground.

Is it too late to plant in Chadbourn?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Feb 5; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 30 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

What an experienced grower watches for around here
In and around Chadbourn, two things run higher than the national average within ~10 miles of Chadbourn — Superfund (5 sites) and Underground Storage Tanks (146 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Chadbourn
Everything above resolves to Chadbourn as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Columbus County’s record because no 30-year normal resolves at this town’s own centroid. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Chadbourn
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Columbus County’s record, because none resolves here; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Chadbourn
When does frost risk typically end in Chadbourn?
The last hard freeze (28°F) in Chadbourn typically lands around Mar 5, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Mar 26.
When is the first frost in Chadbourn?
The first hard freeze (28°F) in Chadbourn typically arrives around Nov 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 16, so the watching starts about Oct 31 — about 270 days after the spring freeze cleared.
How long is the growing season in Chadbourn?
Measured between 28°F hard freezes, Chadbourn sees about 270 frost-free days — roughly Mar 5 through Nov 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 26 to Nov 16, about 235 days.
Is the soil safe to grow vegetables in Chadbourn?
The federal record around Chadbourn is a meaningful one — 207 documented sites, mostly Underground Storage Tanks entries (146), the nearest Underground Storage Tanks record under a tenth of a mile out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Chadbourn?
From about Oct 31 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Nov 30 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Nov 30. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
