Cade, Louisiana, sits in USDA hardiness zone 9a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Growers here do well with artichoke, fig, california poppy, and cabbage — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Cade, 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 Cade 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 Cade
Each reading below is measured for Cade itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsCade runs about 308 days between hard freezes (read from St. Martin Parish, the closest normal to Cade) — 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
MeasuredCade 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 Cade is in
Cade sits in the Western Gulf Coastal Plain — EPA Level III, inside the wider Great Plains. That is read at Cade's own centroid, and it is not what its county reads: St. Martin 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 Cade?
Almost never — the real question is what to plant next. 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 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 Cade, Brownfields runs higher than the national average — 939 sites within ~10 miles of Cade. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

Your land is one point inside Cade
Everything above resolves to Cade as a whole — one PHZM band, read across 4K acres, with hard-freeze dates borrowed from St. Martin 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 Cade
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. Martin 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 Cade
When does frost risk typically end in Cade?
The last hard freeze (28°F) in Cade 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 Cade?
The first hard freeze (28°F) in Cade 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 308 days after the spring freeze cleared.
How long is the growing season in Cade?
Measured between 28°F hard freezes, Cade sees about 308 frost-free days — roughly Feb 1 through Dec 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 22 to Nov 22, about 273 days.
Is the soil safe to grow vegetables in Cade?
The federal record around Cade is a meaningful one — 1,710 documented sites, mostly Brownfields entries (939), 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 Cade?
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.

- Soil character — no town-scale survey exists, so Cade's 4,299 acres read through its county's SSURGO summaryfrom St. Martin County
- Growing-degree days and winter chill — measured county-wide only, so the county page carries themfrom St. Martin County
