Manteo, North Carolina, sits in USDA hardiness zone 9a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Reliable performers under these conditions include artichoke, fig, california poppy, and cabbage; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Manteo, 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 Manteo 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 Manteo
Each reading below is measured for Manteo itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsManteo runs about 303 days between hard freezes (read from Dare County, the closest normal to Manteo) — 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
MeasuredManteo sits in USDA hardiness zone 9a.
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 Manteo is in
Manteo sits in the Middle Atlantic Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Manteo's own centroid rather than borrowed from Dare County.

Is it too late to plant in Manteo?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 18 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

What an experienced grower watches for around here
In and around Manteo, Nitrate runs higher than the national average — 46 sites within ~10 miles of Manteo. That's not a problem with your land — it's information about it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Manteo
Everything above resolves to Manteo as a whole — one PHZM band, read across 1K acres, with hard-freeze dates borrowed from Dare 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 Manteo
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 Dare 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 Manteo
When does frost risk typically end in Manteo?
The last hard freeze (28°F) in Manteo typically lands around Feb 18, 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 11.
When is the first frost in Manteo?
The first hard freeze (28°F) in Manteo typically arrives around Dec 18, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 4, so the watching starts about Nov 18 — about 303 days after the spring freeze cleared.
How long is the growing season in Manteo?
Measured between 28°F hard freezes, Manteo sees about 303 frost-free days — roughly Feb 18 through Dec 18, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 11 to Dec 4, about 268 days.
Is the soil safe to grow vegetables in Manteo?
The federal record around Manteo is a meaningful one — 147 documented sites, mostly Underground Storage Tanks entries (75), the nearest Brownfields record about 0.5 miles 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 Manteo?
From about Nov 18 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 Dec 18 (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 Dec 18. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
