Mullin, Texas, sits in USDA hardiness zone 8b — a zone band wide enough that plant choice, not possibility, is the interesting question.
These conditions suit cabbage, fig, california poppy, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Mullin, no two yards are alike.

What this means for growing in Mullin
Each reading below is measured for Mullin itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsMullin runs about 273 days between hard freezes (read from Mills County, the closest normal to Mullin) — 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
MeasuredMullin 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.

Is it too late to plant in Mullin?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Jan 29; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 26 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 26 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

What an experienced grower watches for around here
In and around Mullin, Underground Storage Tanks runs higher than the national average — 30 sites within ~10 miles of Mullin. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
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 Mullin
Everything above resolves to Mullin as a whole — one PHZM band, read across 300 acres, with hard-freeze dates borrowed from Mills 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 Mullin
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 Mills 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 Mullin
When does frost risk typically end in Mullin?
The last hard freeze (28°F) in Mullin typically lands around Feb 26, 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 19.
When is the first frost in Mullin?
The first hard freeze (28°F) in Mullin typically arrives around Nov 26, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 12, so the watching starts about Oct 27 — about 273 days after the spring freeze cleared.
How long is the growing season in Mullin?
Measured between 28°F hard freezes, Mullin sees about 273 frost-free days — roughly Feb 26 through Nov 26, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 19 to Nov 12, about 238 days.
Is the soil safe to grow vegetables in Mullin?
The federal record around Mullin is light — 31 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (30), the nearest Underground Storage Tanks record about 0.3 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 Mullin?
From about Oct 27 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 26 (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 26. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
