Bertie County, in North Carolina, sits in USDA hardiness zone 8a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Growers here do well with cabbage, fig, california poppy, and collard greens — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Bertie County lies within Tidewater & Chesapeake — a regional growing area with its own character.

Bertie County — the short answer
Bertie County, North Carolina: USDA zone 8a, about 249 days between hard freezes, across 447K acres.

Heat and winter chill in Bertie County
Across a year, Bertie County accumulates about 4,537 growing degree days above 50°F, about 147 more than the middle North Carolina county — ahead of 56 of North Carolina’s 100 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.
Winter banks about 1,662 hours below 45°F, 101 fewer than the North Carolina middle of 1,763. Chill is what tells a fruit tree its dormancy is over, and it is set by climate rather than by anything you can build.

Soil in Bertie County
Across Bertie County, the ground is predominantly Ultisols, where Leaf, Craven, and Roanoke are the most extensive named soil series. The soil is generally poorly drained with a loam surface. Topsoil pH runs about 4.5–5.1, very strongly acidic. Rainfall drains through hydrologic group B/D soils.

How the ground varies across Bertie County
The USDA soil survey maps 39% of Bertie County as poorly drained — but another 56% drains differently: 23% moderately well drained, 15% somewhat poorly drained.
Leaf is the most extensive named soil at 15% of mapped acres, then Craven (8%) and Roanoke (8%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Bertie County
Each reading below is measured for Bertie County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Bertie County are poorly drained, in hydrologic group B/D — ground that sheds water slowly.
Beds can stay saturated for days after heavy rain, and the roots of most vegetables, berries, and fruit trees suffocate or rot in soil that never drains.
Raised beds or mounded rows lift roots above the wet zone; choose water-tolerant crops for the lowest spots.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Bertie County runs about pH 4.5–5.1, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Season length
MeasuredBertie County runs about 249 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredBertie County sits in USDA hardiness zone 8a.
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 Bertie County is in
Bertie County sits in the Middle Atlantic Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. One consistent ecological setting across the whole county.
What Grows in Bertie County
We scored all 1,086 plants against Bertie County's own USDA zone 8a and its own 249-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's North Carolina profile.
Is it too late to plant in Bertie County?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Feb 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 17 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 21 — long-season crops need about 90 days of runway, quick greens only 30. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.

What an experienced grower watches for around here
In and around Bertie County, Underground Storage Tanks runs higher than the national average — 180 sites across Bertie County. That's not a problem with your land — it's information about it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Bertie County
Everything above resolves to Bertie County as a whole — one PHZM band and one county frost record, read across 447K acres. 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 county 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 county average.

How we know this about Bertie County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Bertie County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Bertie County
When does frost risk typically end in Bertie County?
The last hard freeze (28°F) in Bertie County typically lands around Mar 17, 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 Apr 7.
How long is the growing season in Bertie County?
Measured between 28°F hard freezes, Bertie County sees about 249 frost-free days — roughly Mar 17 through Nov 21, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 7 to Nov 7, about 214 days.
Is the soil safe to grow vegetables in Bertie County?
The federal record around Bertie County is a meaningful one — 224 documented sites, mostly Underground Storage Tanks entries (180), the nearest Underground Storage Tanks record about 0.8 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.
