Oakhurst, Texas, sits in USDA hardiness zone 9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
Among the crops suited to this profile: artichoke, fig, california poppy, and cabbage. The site-level story — soil, sun, drainage — decides the rest.
Even in Oakhurst, 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 Oakhurst 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 Oakhurst
Each reading below is measured for Oakhurst itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsOakhurst runs about 300 days between hard freezes (read from San Jacinto County, the closest normal to Oakhurst) — 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
MeasuredOakhurst 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 Oakhurst is in
Oakhurst sits in the South Central Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Oakhurst's own centroid rather than borrowed from San Jacinto County.

Is it too late to plant in Oakhurst?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. 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 7 — 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.

- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

Your land is one point inside Oakhurst
Everything above resolves to Oakhurst as a whole — one PHZM band, read across 988 acres, with hard-freeze dates borrowed from San Jacinto 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 Oakhurst
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 San Jacinto 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 Oakhurst
When does frost risk typically end in Oakhurst?
The last hard freeze (28°F) in Oakhurst 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 Oakhurst?
The first hard freeze (28°F) in Oakhurst typically arrives around Dec 7, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 23, so the watching starts about Nov 7 — about 300 days after the spring freeze cleared.
How long is the growing season in Oakhurst?
Measured between 28°F hard freezes, Oakhurst sees about 300 frost-free days — roughly Feb 10 through Dec 7, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 3 to Nov 23, about 265 days.
Is the soil safe to grow vegetables in Oakhurst?
The federal record around Oakhurst shows 22 documented sites, mostly Underground Storage Tanks entries (16), the nearest Underground Storage Tanks record about 5.5 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 Oakhurst?
From about Nov 7 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 7 (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 7. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
