Mansura, Louisiana, sits in USDA hardiness zone 9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
On paper, artichoke, fig, california poppy, and cabbage all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Mansura, 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 Mansura 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 Mansura
Each reading below is measured for Mansura itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsMansura runs about 303 days between hard freezes (read from Avoyelles Parish, the closest normal to Mansura) — 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
MeasuredMansura 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 Mansura is in
Mansura sits in the South Central Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Mansura's own centroid, and it is not what its county reads: Avoyelles Parish is mostly Mississippi Alluvial Plain. The wider page above you is answering a different question about different ground.

Is it too late to plant in Mansura?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Jan 9; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 6 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 6 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.

What an experienced grower watches for around here
In and around Mansura, two things run higher than the national average within ~10 miles of Mansura — Nitrate (186 sites) and PFAS (4 sites). 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.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.

Your land is one point inside Mansura
Everything above resolves to Mansura as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Avoyelles Parish’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 Mansura
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 Avoyelles Parish’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 Mansura
When does frost risk typically end in Mansura?
The last hard freeze (28°F) in Mansura typically lands around Feb 6, 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 Feb 27.
When is the first frost in Mansura?
The first hard freeze (28°F) in Mansura typically arrives around Dec 6, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 22, so the watching starts about Nov 6 — about 303 days after the spring freeze cleared.
How long is the growing season in Mansura?
Measured between 28°F hard freezes, Mansura sees about 303 frost-free days — roughly Feb 6 through Dec 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 27 to Nov 22, about 268 days.
Is the soil safe to grow vegetables in Mansura?
The federal record around Mansura is a meaningful one — 439 documented sites, mostly Nitrate entries (186), the nearest Brownfields record about 0.1 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 Mansura?
From about Nov 6 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 6 (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 6. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
