Benton, Louisiana, sits in USDA hardiness zone 8b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
A short list that earns its place here — cabbage, fig, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Benton, no two yards are alike.

What this means for growing in Benton
Each reading below is measured for Benton itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsBenton runs about 279 days between hard freezes (read from Bossier Parish, the closest normal to Benton) — 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
MeasuredBenton 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 Benton is in
Benton sits in the South Central Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Benton's own centroid rather than borrowed from Bossier Parish.

Is it too late to plant in Benton?
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 25; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 22 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 28 — 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.

What an experienced grower watches for around here
In and around Benton, two things run higher than the national average within ~10 miles of Benton — PFAS (4 sites) and Nitrate (106 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
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 Benton
Everything above resolves to Benton as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Bossier 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 Benton
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 Bossier 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 Benton
When does frost risk typically end in Benton?
The last hard freeze (28°F) in Benton typically lands around Feb 22, 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 15.
When is the first frost in Benton?
The first hard freeze (28°F) in Benton typically arrives around Nov 28, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 14, so the watching starts about Oct 29 — about 279 days after the spring freeze cleared.
How long is the growing season in Benton?
Measured between 28°F hard freezes, Benton sees about 279 frost-free days — roughly Feb 22 through Nov 28, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 15 to Nov 14, about 244 days.
Is the soil safe to grow vegetables in Benton?
The federal record around Benton is a meaningful one — 297 documented sites, mostly Nitrate entries (106), the nearest Nitrate record about 0.4 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 Benton?
From about Oct 29 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 28 (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 28. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
