Newton, Mississippi, sits in USDA hardiness zone 8b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Among the crops suited to this profile: cabbage, fig, california poppy, and collard greens. The site-level story — soil, sun, drainage — decides the rest.
Even in Newton, 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 Newton lot. Enter your address and we'll score 1,085 plants against your land's actual soil, sun, and frost.

What this means for growing in Newton
Each reading below is measured for Newton itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsNewton runs about 268 days between hard freezes (read from Newton County, the closest normal to Newton) — 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
MeasuredNewton 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 Newton is in
Newton sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Newton's own centroid rather than borrowed from Newton County.

Is it too late to plant in Newton?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 30; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 22 — 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 Newton, two things run higher than the national average within ~10 miles of Newton — Toxics Release Inventory (9 sites) and Underground Storage Tanks (68 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Newton
Everything above resolves to Newton as a whole — one PHZM band, read across 5K acres, with hard-freeze dates borrowed from Newton 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 Newton
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 Newton 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 Newton
When does frost risk typically end in Newton?
The last hard freeze (28°F) in Newton typically lands around Feb 27, 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 20.
When is the first frost in Newton?
The first hard freeze (28°F) in Newton typically arrives around Nov 22, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 8, so the watching starts about Oct 23 — about 268 days after the spring freeze cleared.
How long is the growing season in Newton?
Measured between 28°F hard freezes, Newton sees about 268 frost-free days — roughly Feb 27 through Nov 22, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 20 to Nov 8, about 233 days.
Is the soil safe to grow vegetables in Newton?
The federal record around Newton shows 109 documented sites, mostly Underground Storage Tanks entries (68), the nearest Underground Storage Tanks record about 0.2 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Newton?
From about Oct 23 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 22 (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 22. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
