State Line, Mississippi, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
On paper, cabbage, fig, california poppy, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in State Line, 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 State Line 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 State Line
Each reading below is measured for State Line itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsState Line runs about 273 days between hard freezes (read from Wayne County, the closest normal to State Line) — 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
MeasuredState Line 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 State Line is in
State Line sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at State Line's own centroid rather than borrowed from Wayne County.

Is it too late to plant in State Line?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Jan 27; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 24 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 24 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around State Line, Nitrate runs higher than the national average — 10 sites within ~10 miles of State Line. That's not a problem with your land — it's information about it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
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 State Line
Everything above resolves to State Line as a whole — one PHZM band, read across 3K acres, with hard-freeze dates borrowed from Wayne County’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 State Line
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 Wayne 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 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 State Line
When does frost risk typically end in State Line?
The last hard freeze (28°F) in State Line typically lands around Feb 24, 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 17.
When is the first frost in State Line?
The first hard freeze (28°F) in State Line typically arrives around Nov 24, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 10, so the watching starts about Oct 25 — about 273 days after the spring freeze cleared.
How long is the growing season in State Line?
Measured between 28°F hard freezes, State Line sees about 273 frost-free days — roughly Feb 24 through Nov 24, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 17 to Nov 10, about 238 days.
Is the soil safe to grow vegetables in State Line?
The federal record around State Line is light — 34 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (20), the nearest Underground Storage Tanks record under a tenth of a mile 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 State Line?
From about Oct 25 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 24 (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 24. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
