Dorseyville, Louisiana, sits in USDA hardiness zone 9b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Expect okra, satsuma orange, live oak, and pecan to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.

What this means for growing in Dorseyville
Each reading below is measured for Dorseyville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsDorseyville runs about 309 days between hard freezes (read from Iberville Parish, the closest normal to Dorseyville) — 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
MeasuredDorseyville sits in USDA hardiness zone 9b.
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 Dorseyville is in
Dorseyville sits in the Mississippi Alluvial Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Dorseyville's own centroid rather than borrowed from Iberville Parish.

Plants matched to Dorseyville's USDA zones 9b, ordered by how much hardiness margin each has here — the ones with room to spare at both ends of this town's band lead. Each links to its full growing profile.
Is it too late to plant in Dorseyville?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 4; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 1 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 7 — 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 Dorseyville, Toxics Release Inventory runs higher than the national average — 53 sites within ~10 miles of Dorseyville. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.

Your land is one point inside Dorseyville
Everything above resolves to Dorseyville as a whole — one PHZM band, read across 97 acres, with hard-freeze dates borrowed from Iberville 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 Dorseyville
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 Iberville 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 Dorseyville
When does frost risk typically end in Dorseyville?
The last hard freeze (28°F) in Dorseyville typically lands around Feb 1, 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 22.
When is the first frost in Dorseyville?
The first hard freeze (28°F) in Dorseyville typically arrives around Dec 7, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 23, so the watching starts about Nov 7 — about 309 days after the spring freeze cleared.
How long is the growing season in Dorseyville?
Measured between 28°F hard freezes, Dorseyville sees about 309 frost-free days — roughly Feb 1 through Dec 7, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 22 to Nov 23, about 274 days.
Is the soil safe to grow vegetables in Dorseyville?
The federal record around Dorseyville is a meaningful one — 514 documented sites, mostly Brownfields entries (217), the nearest Nitrate record under a tenth of a mile 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 Dorseyville?
From about Nov 7 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 7 (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 7. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
