Roxton, Texas, sits in USDA hardiness zone 8b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
A short list that earns its place here — cabbage, fig, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Roxton, 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 Roxton 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 Roxton
Each reading below is measured for Roxton itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsRoxton runs about 271 days between hard freezes (read from Lamar County, the closest normal to Roxton) — 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
MeasuredRoxton 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 Roxton is in
Roxton sits in the Texas Blackland Prairies — EPA Level III, inside the wider Great Plains. That is read at Roxton's own centroid rather than borrowed from Lamar County.

Is it too late to plant in Roxton?
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 25 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

Know Before You Grow
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •Large animal operations push nitrates and bacteria downstream. Below one, test your water.
- •PFAS do not break down in groundwater. Irrigate from a tested source.

Your land is one point inside Roxton
Everything above resolves to Roxton as a whole — one PHZM band, read across 552 acres, with hard-freeze dates borrowed from Lamar 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 Roxton
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 Lamar 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 Roxton
When does frost risk typically end in Roxton?
The last hard freeze (28°F) in Roxton 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 Roxton?
The first hard freeze (28°F) in Roxton typically arrives around Nov 25, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 11, so the watching starts about Oct 26 — about 271 days after the spring freeze cleared.
How long is the growing season in Roxton?
Measured between 28°F hard freezes, Roxton sees about 271 frost-free days — roughly Feb 27 through Nov 25, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 20 to Nov 11, about 236 days.
Is the soil safe to grow vegetables in Roxton?
The federal record around Roxton is light — 4 documented sites across the 9 federal source types we checked, mostly Brownfields entries (1), the nearest PFAS record about 1.3 miles 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 Roxton?
From about Oct 26 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 25 (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 25. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
