Las Haciendas, Texas, sits in USDA hardiness zone 9b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Expect okra, meyer lemon, california poppy, and artichoke to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Las Haciendas, 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 Las Haciendas 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 Las Haciendas
Each reading below is measured for Las Haciendas itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsLas Haciendas runs about 326 days between hard freezes (read from Webb County, the closest normal to Las Haciendas) — 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
MeasuredLas Haciendas 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 Las Haciendas is in
Las Haciendas sits in the Southern Texas Plains — EPA Level III, inside the wider Great Plains. That is read at Las Haciendas's own centroid rather than borrowed from Webb County.

Is it too late to plant in Las Haciendas?
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 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 25 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 17 — 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.

Your land is one point inside Las Haciendas
Everything above resolves to Las Haciendas as a whole — one PHZM band, read across 151 acres, with hard-freeze dates borrowed from Webb 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 Las Haciendas
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 Webb 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 Las Haciendas
When does frost risk typically end in Las Haciendas?
The last hard freeze (28°F) in Las Haciendas typically lands around Jan 25, 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 15.
When is the first frost in Las Haciendas?
The first hard freeze (28°F) in Las Haciendas typically arrives around Dec 17, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 3, so the watching starts about Nov 17 — about 326 days after the spring freeze cleared.
How long is the growing season in Las Haciendas?
Measured between 28°F hard freezes, Las Haciendas sees about 326 frost-free days — roughly Jan 25 through Dec 17, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 15 to Dec 3, about 291 days.
Is the soil safe to grow vegetables in Las Haciendas?
The federal record around Las Haciendas is light — 2 documented sites across the 9 federal source types we checked, mostly Nitrate entries (2), the nearest Nitrate record about 7.1 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 Las Haciendas?
From about Nov 17 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 17 (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 17. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
