Delacroix, Louisiana, sits in USDA hardiness zone 9b — a zone band wide enough that plant choice, not possibility, is the interesting question.
These conditions suit okra, meyer lemon, california poppy, and artichoke — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Delacroix, 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 Delacroix 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 Delacroix
Each reading below is measured for Delacroix itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
From county recordsDelacroix runs about 338 days between hard freezes (read from St. Bernard Parish, the closest normal to Delacroix) — 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
MeasuredDelacroix 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 Delacroix is in
Delacroix sits in the Mississippi Alluvial Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Delacroix's own centroid rather than borrowed from St. Bernard Parish.

Is it too late to plant in Delacroix?
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 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 16 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 20 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

Know Before You Grow
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

Your land is one point inside Delacroix
Everything above resolves to Delacroix as a whole — one PHZM band, read across 141 acres, with hard-freeze dates borrowed from St. Bernard 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 Delacroix
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 St. Bernard 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 Delacroix
When does frost risk typically end in Delacroix?
The last hard freeze (28°F) in Delacroix typically lands around Jan 16, 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 6.
When is the first frost in Delacroix?
The first hard freeze (28°F) in Delacroix typically arrives around Dec 20, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 6, so the watching starts about Nov 20 — about 338 days after the spring freeze cleared.
How long is the growing season in Delacroix?
Measured between 28°F hard freezes, Delacroix sees about 338 frost-free days — roughly Jan 16 through Dec 20, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 6 to Dec 6, about 303 days.
Is the soil safe to grow vegetables in Delacroix?
The federal record around Delacroix is light — 42 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (20), the nearest Nitrate record about 0.2 miles out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do I protect my plants from frost in Delacroix?
From about Nov 20 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 20 (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 20. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
