Las Lomitas, Texas, sits in USDA hardiness zone 9b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Among the crops suited to this profile: okra, meyer lemon, california poppy, and artichoke. The site-level story — soil, sun, drainage — decides the rest.
Even in Las Lomitas, 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 Lomitas 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 Lomitas
Each reading below is measured for Las Lomitas itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsLas Lomitas runs about 329 days between hard freezes (read from Jim Hogg County, the closest normal to Las Lomitas) — 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 Lomitas 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 Lomitas is in
Las Lomitas sits in the Southern Texas Plains — EPA Level III, inside the wider Great Plains. That is read at Las Lomitas's own centroid, and it is not what its county reads: Jim Hogg County is mostly Western Gulf Coastal Plain. The wider page above you is answering a different question about different ground.

Is it too late to plant in Las Lomitas?
For most of the year, no — what changes is which crops still fit the days remaining. 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 20 — 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 Las Lomitas, two things run higher than the national average within ~10 miles of Las Lomitas — Nitrate (16 sites) and Toxics Release Inventory (3 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside Las Lomitas
Everything above resolves to Las Lomitas as a whole — one PHZM band, read across 3K acres, with hard-freeze dates borrowed from Jim Hogg 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 Lomitas
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 Jim Hogg 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 Lomitas
When does frost risk typically end in Las Lomitas?
The last hard freeze (28°F) in Las Lomitas 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 Lomitas?
The first hard freeze (28°F) in Las Lomitas typically arrives around Dec 20, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 6, so the watching starts about Nov 20 — about 329 days after the spring freeze cleared.
How long is the growing season in Las Lomitas?
Measured between 28°F hard freezes, Las Lomitas sees about 329 frost-free days — roughly Jan 25 through Dec 20, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 15 to Dec 6, about 294 days.
Is the soil safe to grow vegetables in Las Lomitas?
The federal record around Las Lomitas is light — 48 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (25), the nearest Underground Storage Tanks record about 1.6 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 Lomitas?
From about Nov 20 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 20 (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 20. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
