Poynor, Texas, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
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 Poynor, 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 Poynor 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 Poynor
Each reading below is measured for Poynor itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsPoynor runs about 282 days between hard freezes (read from Henderson County, the closest normal to Poynor) — 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
MeasuredPoynor sits in USDA hardiness zone 8b.
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 Poynor is in
Poynor sits in the South Central Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Poynor's own centroid, and it is not what its county reads: Henderson 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 Poynor?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 19 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 28 — 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.

What an experienced grower watches for around here
In and around Poynor, Underground Storage Tanks runs higher than the national average — 23 sites within ~10 miles of Poynor. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Poynor
Everything above resolves to Poynor as a whole — one PHZM band, read across 2K acres, with hard-freeze dates borrowed from Henderson 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 Poynor
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 Henderson 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 Poynor
When does frost risk typically end in Poynor?
The last hard freeze (28°F) in Poynor typically lands around Feb 19, 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 12.
When is the first frost in Poynor?
The first hard freeze (28°F) in Poynor typically arrives around Nov 28, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 14, so the watching starts about Oct 29 — about 282 days after the spring freeze cleared.
How long is the growing season in Poynor?
Measured between 28°F hard freezes, Poynor sees about 282 frost-free days — roughly Feb 19 through Nov 28, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 12 to Nov 14, about 247 days.
Is the soil safe to grow vegetables in Poynor?
The federal record around Poynor is light — 32 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (23), the nearest Underground Storage Tanks record about 0.5 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 Poynor?
From about Oct 29 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 28 (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 28. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
