Tulsita, Texas, sits in USDA hardiness zone 9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
Reliable performers under these conditions include okra, black-eyed pea, tomato, and jalapeno; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Tulsita, 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 Tulsita 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 Tulsita
Each reading below is measured for Tulsita itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsTulsita runs about 319 days between hard freezes (read from Bee County, the closest normal to Tulsita) — 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
MeasuredTulsita 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 Tulsita is in
Tulsita sits in the East Central Texas Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Tulsita's own centroid rather than borrowed from Bee County.
What Grows in Tulsita
Plants matched to Tulsita's USDA zones 9a, ordered by how much hardiness margin each has here — the ones with room to spare at both ends of this town's band lead. Each links to its full growing profile.
Is it too late to plant in Tulsita?
Usually not — gardeners here simply switch what goes in the ground as the season moves. 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 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 12 — 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.

What an experienced grower watches for around here
In and around Tulsita, Nitrate runs higher than the national average — 58 sites within ~10 miles of Tulsita. 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.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Tulsita
Everything above resolves to Tulsita as a whole — one PHZM band, read across 186 acres, with hard-freeze dates borrowed from Bee 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 Tulsita
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 Bee 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 Tulsita
When does frost risk typically end in Tulsita?
The last hard freeze (28°F) in Tulsita typically lands around Jan 27, 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 17.
When is the first frost in Tulsita?
The first hard freeze (28°F) in Tulsita typically arrives around Dec 12, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 28, so the watching starts about Nov 12 — about 319 days after the spring freeze cleared.
How long is the growing season in Tulsita?
Measured between 28°F hard freezes, Tulsita sees about 319 frost-free days — roughly Jan 27 through Dec 12, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 17 to Nov 28, about 284 days.
Is the soil safe to grow vegetables in Tulsita?
The federal record around Tulsita shows 67 documented sites, mostly Nitrate entries (58), the nearest Nitrate record about 1.4 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 Tulsita?
From about Nov 12 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 12 (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 12. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
