Orrum, North Carolina, sits in USDA hardiness zone 8b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Among the crops suited to this profile: cabbage, fig, california poppy, and collard greens. The site-level story — soil, sun, drainage — decides the rest.
Even in Orrum, 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 Orrum 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 Orrum
Each reading below is measured for Orrum itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsOrrum runs about 262 days between hard freezes (read from Robeson County, the closest normal to Orrum) — 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
MeasuredOrrum 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 Orrum is in
Orrum sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Orrum's own centroid rather than borrowed from Robeson County.

Is it too late to plant in Orrum?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Feb 7; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 7 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 24 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

What an experienced grower watches for around here
In and around Orrum, two things run higher than the national average within ~10 miles of Orrum — Toxics Release Inventory (8 sites) and Underground Storage Tanks (78 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Orrum
Everything above resolves to Orrum as a whole — one PHZM band, read across 306 acres, with hard-freeze dates borrowed from Robeson 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 Orrum
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 Robeson 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 Orrum
When does frost risk typically end in Orrum?
The last hard freeze (28°F) in Orrum typically lands around Mar 7, 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 28.
When is the first frost in Orrum?
The first hard freeze (28°F) in Orrum typically arrives around Nov 24, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 10, so the watching starts about Oct 25 — about 262 days after the spring freeze cleared.
How long is the growing season in Orrum?
Measured between 28°F hard freezes, Orrum sees about 262 frost-free days — roughly Mar 7 through Nov 24, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 28 to Nov 10, about 227 days.
Is the soil safe to grow vegetables in Orrum?
The federal record around Orrum shows 110 documented sites, mostly Underground Storage Tanks entries (78), the nearest Underground Storage Tanks record under a tenth of a mile out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Orrum?
From about Oct 25 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 24 (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 24. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
