Coyanosa, Texas, sits in USDA hardiness zone 8a — a zone band wide enough that plant choice, not possibility, is the interesting question.
On paper, cabbage, fig, california poppy, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Coyanosa, 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 Coyanosa 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 Coyanosa
Each reading below is measured for Coyanosa itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredCoyanosa runs about 259 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.

Winter hardiness
MeasuredCoyanosa sits in USDA hardiness zone 8a.
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 Coyanosa is in
Coyanosa sits in the Chihuahuan Deserts — EPA Level III, inside the wider North American Deserts. That is read at Coyanosa's own centroid rather than borrowed from Pecos County.

Is it too late to plant in Coyanosa?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Feb 4; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 4 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 18 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.

Know Before You Grow
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.
- •TRI facilities report what they release. Check the wind — downwind beds catch more of it.
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.

Your land is one point inside Coyanosa
Everything above resolves to Coyanosa as a whole — one PHZM band and one 28°F frost record, read across 138 acres. 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 Coyanosa
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 Coyanosa’s own record; 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 Coyanosa
When does frost risk typically end in Coyanosa?
The last hard freeze (28°F) in Coyanosa typically lands around Mar 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 Mar 25.
When is the first frost in Coyanosa?
The first hard freeze (28°F) in Coyanosa typically arrives around Nov 18, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 4, so the watching starts about Oct 19 — about 259 days after the spring freeze cleared.
How long is the growing season in Coyanosa?
Measured between 28°F hard freezes, Coyanosa sees about 259 frost-free days — roughly Mar 4 through Nov 18, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 25 to Nov 4, about 224 days.
Is the soil safe to grow vegetables in Coyanosa?
The federal record around Coyanosa is light — 19 documented sites across the 9 federal source types we checked, mostly Nitrate entries (10), the nearest Nitrate record about 0.9 miles out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do I protect my plants from frost in Coyanosa?
From about Oct 19 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 Nov 18 (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 Nov 18. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
