South Frydek, Texas, sits in USDA hardiness zone 9a — 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 — artichoke, fig, california poppy, and cabbage — with any one site's soil, sun, and drainage making the final cut.
Even in South Frydek, no two yards are alike.

What this means for growing in South Frydek
Each reading below is measured for South Frydek itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsSouth Frydek runs about 304 days between hard freezes (read from Austin County, the closest normal to South Frydek) — 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
MeasuredSouth Frydek 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 South Frydek is in
South Frydek sits in the Western Gulf Coastal Plain — EPA Level III, inside the wider Great Plains. That is read at South Frydek's own centroid rather than borrowed from Austin County.

Is it too late to plant in South Frydek?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 7; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 4 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 5 — 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.

What an experienced grower watches for around here
In and around South Frydek, two things run higher than the national average within ~10 miles of South Frydek — PFAS (3 sites) and Toxics Release Inventory (13 sites). That's not a problem with your land — it's information about it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside South Frydek
Everything above resolves to South Frydek as a whole — one PHZM band, read across 1K acres, with hard-freeze dates borrowed from Austin 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 South Frydek
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 Austin 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 South Frydek
When does frost risk typically end in South Frydek?
The last hard freeze (28°F) in South Frydek typically lands around Feb 4, 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 25.
When is the first frost in South Frydek?
The first hard freeze (28°F) in South Frydek typically arrives around Dec 5, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 21, so the watching starts about Nov 5 — about 304 days after the spring freeze cleared.
How long is the growing season in South Frydek?
Measured between 28°F hard freezes, South Frydek sees about 304 frost-free days — roughly Feb 4 through Dec 5, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 25 to Nov 21, about 269 days.
Is the soil safe to grow vegetables in South Frydek?
The federal record around South Frydek is a meaningful one — 154 documented sites, mostly Underground Storage Tanks entries (83), the nearest Brownfields record about 2.9 miles 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 South Frydek?
From about Nov 5 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 5 (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 5. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
