Moulton, Texas, sits in USDA hardiness zone 9a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Reliable performers under these conditions include artichoke, fig, california poppy, and cabbage; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Moulton, 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 Moulton 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 Moulton
Each reading below is measured for Moulton itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsMoulton runs about 313 days between hard freezes (read from Lavaca County, the closest normal to Moulton) — 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
MeasuredMoulton 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 Moulton is in
Moulton sits in the Texas Blackland Prairies — EPA Level III, inside the wider Great Plains. That is read at Moulton's own centroid rather than borrowed from Lavaca County.

Is it too late to plant in Moulton?
Almost never — the real question is what to plant next. 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 29 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 8 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

A note from Gnorman
What an experienced grower watches for around here
In and around Moulton, Toxics Release Inventory runs higher than the national average — 4 sites within ~10 miles of Moulton. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside Moulton
Everything above resolves to Moulton as a whole — one PHZM band, read across 534 acres, with hard-freeze dates borrowed from Lavaca 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 Moulton
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 Lavaca 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 Moulton
When does frost risk typically end in Moulton?
The last hard freeze (28°F) in Moulton typically lands around Jan 29, 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 19.
When is the first frost in Moulton?
The first hard freeze (28°F) in Moulton typically arrives around Dec 8, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 24, so the watching starts about Nov 8 — about 313 days after the spring freeze cleared.
How long is the growing season in Moulton?
Measured between 28°F hard freezes, Moulton sees about 313 frost-free days — roughly Jan 29 through Dec 8, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 19 to Nov 24, about 278 days.
Is the soil safe to grow vegetables in Moulton?
The federal record around Moulton shows 56 documented sites, mostly Underground Storage Tanks entries (33), the nearest Underground Storage Tanks record under a tenth of a mile 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 Moulton?
From about Nov 8 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 8 (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 8. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Moulton's scale — its 9a band and its 313-day season. Your yard writes its own version of Moulton's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
