Mayersville, Mississippi, sits in USDA hardiness zone 8b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Growers here do well with cabbage, fig, california poppy, and collard greens — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Mayersville, 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 Mayersville 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 Mayersville
Each reading below is measured for Mayersville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsMayersville runs about 287 days between hard freezes (read from Issaquena County, the closest normal to Mayersville) — 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
MeasuredMayersville 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 Mayersville is in
Mayersville sits in the Mississippi Alluvial Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Mayersville's own centroid rather than borrowed from Issaquena County.

Is it too late to plant in Mayersville?
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 19; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 16 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 30 — 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 Mayersville, Nitrate runs higher than the national average — 46 sites within ~10 miles of Mayersville. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around 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 Mayersville
Everything above resolves to Mayersville as a whole — one PHZM band, read across 705 acres, with hard-freeze dates borrowed from Issaquena 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 Mayersville
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 Issaquena 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 Mayersville
When does frost risk typically end in Mayersville?
The last hard freeze (28°F) in Mayersville typically lands around Feb 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 Mar 9.
When is the first frost in Mayersville?
The first hard freeze (28°F) in Mayersville typically arrives around Nov 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 16, so the watching starts about Oct 31 — about 287 days after the spring freeze cleared.
How long is the growing season in Mayersville?
Measured between 28°F hard freezes, Mayersville sees about 287 frost-free days — roughly Feb 16 through Nov 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 9 to Nov 16, about 252 days.
Is the soil safe to grow vegetables in Mayersville?
The federal record around Mayersville is a meaningful one — 100 documented sites, mostly Nitrate entries (46), the nearest Underground Storage Tanks record about 0.4 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 Mayersville?
From about Oct 31 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 30 (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 30. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
