San Perlita, Texas, sits in USDA hardiness zone 10a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
These conditions suit okra, meyer lemon, california poppy, and artichoke — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

What this means for growing in San Perlita
Each reading below is measured for San Perlita itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsSan Perlita runs about 338 days between hard freezes (read from Willacy County, the closest normal to San Perlita) — 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
MeasuredSan Perlita sits in USDA hardiness zone 10a.
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 San Perlita is in
San Perlita sits in the Western Gulf Coastal Plain — EPA Level III, inside the wider Great Plains. That is read at San Perlita's own centroid rather than borrowed from Willacy County.

Is it too late to plant in San Perlita?
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 19 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 23 — 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 San Perlita, Underground Storage Tanks runs higher than the national average — 66 sites within ~10 miles of San Perlita. 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 San Perlita
Everything above resolves to San Perlita as a whole — one PHZM band, read across 332 acres, with hard-freeze dates borrowed from Willacy County’s record because no 30-year normal resolves at this city’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 city 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 San Perlita
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Willacy 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 city grain anywhere on this page — there is no city-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 San Perlita
When does frost risk typically end in San Perlita?
The last hard freeze (28°F) in San Perlita typically lands around Jan 19, 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 9.
When is the first frost in San Perlita?
The first hard freeze (28°F) in San Perlita typically arrives around Dec 23, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 9, so the watching starts about Nov 23 — about 338 days after the spring freeze cleared.
How long is the growing season in San Perlita?
Measured between 28°F hard freezes, San Perlita sees about 338 frost-free days — roughly Jan 19 through Dec 23, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 9 to Dec 9, about 303 days.
Is the soil safe to grow vegetables in San Perlita?
The federal record around San Perlita shows 70 documented sites, mostly Underground Storage Tanks entries (66), the nearest Underground Storage Tanks record about 2.1 miles 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 San Perlita?
From about Nov 23 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 23 (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 23. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
