Deweyville, Texas, sits in USDA hardiness zone 9a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Crops well matched to these conditions include artichoke, fig, california poppy, and cabbage — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Deweyville, no two yards are alike.

What this means for growing in Deweyville
Each reading below is measured for Deweyville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsDeweyville runs about 300 days between hard freezes (read from Newton County, the closest normal to Deweyville) — 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
MeasuredDeweyville 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 Deweyville is in
Deweyville sits in the South Central Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Deweyville's own centroid rather than borrowed from Newton County.

Is it too late to plant in Deweyville?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 10; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 7 (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. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

A note from Gnorman
What an experienced grower watches for around here
In and around Deweyville, Nitrate runs higher than the national average — 72 sites within ~10 miles of Deweyville. 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 Deweyville
Everything above resolves to Deweyville as a whole — one PHZM band, read across 7K acres, with hard-freeze dates borrowed from Newton 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 Deweyville
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 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 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 Deweyville
When does frost risk typically end in Deweyville?
The last hard freeze (28°F) in Deweyville typically lands around Feb 7, 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 Feb 28.
When is the first frost in Deweyville?
The first hard freeze (28°F) in Deweyville 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 300 days after the spring freeze cleared.
How long is the growing season in Deweyville?
Measured between 28°F hard freezes, Deweyville sees about 300 frost-free days — roughly Feb 7 through Dec 4, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 28 to Nov 20, about 265 days.
Is the soil safe to grow vegetables in Deweyville?
The federal record around Deweyville shows 120 documented sites, mostly Nitrate entries (72), the nearest Underground Storage Tanks record about 1.1 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 Deweyville?
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.
