Omaha, Texas, sits in USDA hardiness zone 8b — a zone band wide enough that plant choice, not possibility, is the interesting question.
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 Omaha, 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 Omaha lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

Every figure names the dataset it came from. No 30-year normal resolves at this town’s own centroid, so the hard-freeze dates are Morris County’s — the closest measured record, labelled as such rather than passed off as local.

What this means for growing in Omaha
Each reading below is measured for Omaha itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
From county recordsOmaha runs about 274 days between hard freezes (read from Morris County, the closest normal to Omaha) — 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
MeasuredOmaha 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 Omaha is in
Omaha sits in the South Central Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Omaha's own centroid rather than borrowed from Morris County.

Is it too late to plant in Omaha?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Jan 28; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 25 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 26 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Omaha, Nitrate runs higher than the national average — 32 sites within ~10 miles of Omaha. 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 Omaha
Everything above resolves to Omaha as a whole — one PHZM band, read across 929 acres, with hard-freeze dates borrowed from Morris County’s record because no 30-year normal resolves at this city’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 city 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 Omaha
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Morris 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 city grain anywhere on this page — there is no city-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 Omaha
When does frost risk typically end in Omaha?
The last hard freeze (28°F) in Omaha typically lands around Feb 25, 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 18.
When is the first frost in Omaha?
The first hard freeze (28°F) in Omaha typically arrives around Nov 26, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 12, so the watching starts about Oct 27 — about 274 days after the spring freeze cleared.
How long is the growing season in Omaha?
Measured between 28°F hard freezes, Omaha sees about 274 frost-free days — roughly Feb 25 through Nov 26, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 18 to Nov 12, about 239 days.
Is the soil safe to grow vegetables in Omaha?
The federal record around Omaha shows 89 documented sites, mostly Underground Storage Tanks entries (51), the nearest Underground Storage Tanks record about 0.1 miles 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 Omaha?
From about Oct 27 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 26 (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 26. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
