Nicholson, Mississippi, sits in USDA hardiness zone 9a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
The conditions favor artichoke, fig, california poppy, and cabbage, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Nicholson, no two yards are alike.

What this means for growing in Nicholson
Each reading below is measured for Nicholson itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsNicholson runs about 293 days between hard freezes (read from Pearl River County, the closest normal to Nicholson) — 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
MeasuredNicholson 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 Nicholson is in
Nicholson sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Nicholson's own centroid, and it is not what its county reads: Pearl River County is mostly Southeastern Plains. The wider page above you is answering a different question about different ground.

Is it too late to plant in Nicholson?
Usually not — gardeners here simply switch what goes in the ground as the season moves. 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. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

What an experienced grower watches for around here
In and around Nicholson, two things run higher than the national average within ~10 miles of Nicholson — PFAS (4 sites) and Superfund (5 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Nicholson
Everything above resolves to Nicholson as a whole — one PHZM band, read across 4K acres, with hard-freeze dates borrowed from Pearl River 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 Nicholson
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 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 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 Nicholson
When does frost risk typically end in Nicholson?
The last hard freeze (28°F) in Nicholson 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 Nicholson?
The first hard freeze (28°F) in Nicholson 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 Nicholson?
Measured between 28°F hard freezes, Nicholson 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 Nicholson?
The federal record around Nicholson is a meaningful one — 273 documented sites, mostly Underground Storage Tanks entries (118), the nearest Toxics Release Inventory 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 Nicholson?
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.
