Tynan, Texas, sits in USDA hardiness zone 9b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Well-matched crops include okra, meyer lemon, california poppy, and artichoke, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Tynan, 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 Tynan 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 Tynan
Each reading below is measured for Tynan itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
From county recordsTynan runs about 319 days between hard freezes (read from Bee County, the closest normal to Tynan) — 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
MeasuredTynan sits in USDA hardiness zone 9b.
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 Tynan is in
Tynan sits in the Western Gulf Coastal Plain — EPA Level III, inside the wider Great Plains. That is read at Tynan's own centroid, and it is not what its county reads: Bee County is mostly East Central Texas Plains. The wider page above you is answering a different question about different ground.

Is it too late to plant in Tynan?
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 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 12 — 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 Tynan, Nitrate runs higher than the national average — 64 sites within ~10 miles of Tynan. That's not a problem with your land — it's information about 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 Tynan
Everything above resolves to Tynan as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Bee 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 Tynan
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 Bee 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 Tynan
When does frost risk typically end in Tynan?
The last hard freeze (28°F) in Tynan typically lands around Jan 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 Feb 17.
When is the first frost in Tynan?
The first hard freeze (28°F) in Tynan typically arrives around Dec 12, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 28, so the watching starts about Nov 12 — about 319 days after the spring freeze cleared.
How long is the growing season in Tynan?
Measured between 28°F hard freezes, Tynan sees about 319 frost-free days — roughly Jan 27 through Dec 12, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 17 to Nov 28, about 284 days.
Is the soil safe to grow vegetables in Tynan?
The federal record around Tynan shows 93 documented sites, mostly Nitrate entries (64), the nearest Underground Storage Tanks record about 0.5 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 Tynan?
From about Nov 12 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 12 (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 12. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
