Sammy Martinez, 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.
Among the crops suited to this profile: okra, meyer lemon, california poppy, and artichoke. The site-level story — soil, sun, drainage — decides the rest.

What this means for growing in Sammy Martinez
Each reading below is measured for Sammy Martinez itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsSammy Martinez runs about 322 days between hard freezes (read from Starr County, the closest normal to Sammy Martinez) — 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
MeasuredSammy Martinez 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 Sammy Martinez is in
Sammy Martinez sits in the Southern Texas Plains — EPA Level III, inside the wider Great Plains. That is read at Sammy Martinez's own centroid rather than borrowed from Starr County.

Is it too late to plant in Sammy Martinez?
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 21 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 9 — 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 Sammy Martinez, two things run higher than the national average within ~10 miles of Sammy Martinez — PFAS (3 sites) and Underground Storage Tanks (121 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Sammy Martinez
Everything above resolves to Sammy Martinez as a whole — one PHZM band, read across 200 acres, with hard-freeze dates borrowed from Starr 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 Sammy Martinez
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 Starr 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 Sammy Martinez
When does frost risk typically end in Sammy Martinez?
The last hard freeze (28°F) in Sammy Martinez typically lands around Jan 21, 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 11.
When is the first frost in Sammy Martinez?
The first hard freeze (28°F) in Sammy Martinez typically arrives around Dec 9, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 25, so the watching starts about Nov 9 — about 322 days after the spring freeze cleared.
How long is the growing season in Sammy Martinez?
Measured between 28°F hard freezes, Sammy Martinez sees about 322 frost-free days — roughly Jan 21 through Dec 9, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 11 to Nov 25, about 287 days.
Is the soil safe to grow vegetables in Sammy Martinez?
The federal record around Sammy Martinez is a meaningful one — 133 documented sites, mostly Underground Storage Tanks entries (121), the nearest Underground Storage Tanks record about 4.3 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Sammy Martinez?
From about Nov 9 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 9 (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 9. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
