Devine, Texas, sits in USDA hardiness zone 9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
These conditions suit artichoke, fig, california poppy, and cabbage — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Devine, no two yards are alike.

What this means for growing in Devine
Each reading below is measured for Devine itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsDevine runs about 299 days between hard freezes (read from Medina County, the closest normal to Devine) — 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
MeasuredDevine 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 Devine is in
Devine sits in the Southern Texas Plains — EPA Level III, inside the wider Great Plains. That is read at Devine's own centroid rather than borrowed from Medina County.

Is it too late to plant in Devine?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Jan 13; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 10 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 6 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Devine, two things run higher than the national average within ~10 miles of Devine — CAFO (3 sites) and Nitrate (34 sites). That's not a problem with your land — it's information about it.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
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 Devine
Everything above resolves to Devine as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Medina 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 Devine
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 Medina 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 Devine
When does frost risk typically end in Devine?
The last hard freeze (28°F) in Devine typically lands around Feb 10, 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 3.
When is the first frost in Devine?
The first hard freeze (28°F) in Devine typically arrives around Dec 6, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 22, so the watching starts about Nov 6 — about 299 days after the spring freeze cleared.
How long is the growing season in Devine?
Measured between 28°F hard freezes, Devine sees about 299 frost-free days — roughly Feb 10 through Dec 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 3 to Nov 22, about 264 days.
Is the soil safe to grow vegetables in Devine?
The federal record around Devine is a meaningful one — 105 documented sites, mostly Underground Storage Tanks entries (52), the nearest Underground Storage Tanks record under a tenth of a mile 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 Devine?
From about Nov 6 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 6 (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 6. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Devine's scale — its 9a band and its 299-day season. Your yard writes its own version of Devine's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
