Poplarville, Mississippi, sits in USDA hardiness zone 9a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Reliable performers under these conditions include artichoke, fig, california poppy, and cabbage; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Poplarville, no two yards are alike.

What this means for growing in Poplarville
Each reading below is measured for Poplarville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsPoplarville runs about 293 days between hard freezes (read from Pearl River County, the closest normal to Poplarville) — 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
MeasuredPoplarville 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.
USDA PHZM 2023
The kind of country Poplarville is in
Poplarville sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Poplarville's own centroid rather than borrowed from Pearl River County.

Is it too late to plant in Poplarville?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 14 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 4 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

What an experienced grower watches for around here
In and around Poplarville, two things run higher than the national average within ~10 miles of Poplarville — PFAS (3 sites) and Underground Storage Tanks (39 sites). That's not a problem with your land — it's information about it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Poplarville
Everything above resolves to Poplarville as a whole — one PHZM band, read across 3K acres, with hard-freeze dates borrowed from Pearl River County’s record because no 30-year normal resolves at this city’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 city 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 Poplarville
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Pearl River County’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 city grain anywhere on this page — there is no city-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 Poplarville
When does frost risk typically end in Poplarville?
The last hard freeze (28°F) in Poplarville typically lands around Feb 14, 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 7.
When is the first frost in Poplarville?
The first hard freeze (28°F) in Poplarville typically arrives around Dec 4, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 20, so the watching starts about Nov 4 — about 293 days after the spring freeze cleared.
How long is the growing season in Poplarville?
Measured between 28°F hard freezes, Poplarville sees about 293 frost-free days — roughly Feb 14 through Dec 4, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 7 to Nov 20, about 258 days.
Is the soil safe to grow vegetables in Poplarville?
The federal record around Poplarville is a meaningful one — 60 documented sites, mostly Underground Storage Tanks entries (39), the nearest Underground Storage Tanks 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 Poplarville?
From about Nov 4 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 4 (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 4. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
