Pflugerville, Texas, sits in USDA hardiness zone 9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
Among the crops suited to this profile: artichoke, fig, california poppy, and cabbage. The site-level story — soil, sun, drainage — decides the rest.
Even in Pflugerville, 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 Pflugerville 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 Pflugerville
Each reading below is measured for Pflugerville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsPflugerville runs about 299 days between hard freezes (read from Travis County, the closest normal to Pflugerville) — 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
MeasuredPflugerville 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 Pflugerville is in
Pflugerville sits in the Texas Blackland Prairies — EPA Level III, inside the wider Great Plains. That is read at Pflugerville's own centroid, and it is not what its county reads: Travis County is mostly Edwards Plateau. The wider page above you is answering a different question about different ground.

Is it too late to plant in Pflugerville?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Jan 12; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 5 — 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 Pflugerville, two things run higher than the national average within ~10 miles of Pflugerville — PFAS (19 sites) and Toxics Release Inventory (79 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside Pflugerville
Everything above resolves to Pflugerville as a whole — one PHZM band, read across 17K acres, with hard-freeze dates borrowed from Travis 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 Pflugerville
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 Travis 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 Pflugerville
When does frost risk typically end in Pflugerville?
The last hard freeze (28°F) in Pflugerville typically lands around Feb 9, 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 Mar 2.
When is the first frost in Pflugerville?
The first hard freeze (28°F) in Pflugerville typically arrives around Dec 5, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 21, so the watching starts about Nov 5 — about 299 days after the spring freeze cleared.
How long is the growing season in Pflugerville?
Measured between 28°F hard freezes, Pflugerville sees about 299 frost-free days — roughly Feb 9 through Dec 5, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 2 to Nov 21, about 264 days.
Is the soil safe to grow vegetables in Pflugerville?
The federal record around Pflugerville runs heavier than most — 878 documented sites, mostly Underground Storage Tanks entries (498), the nearest Brownfields record about 0.3 miles out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
How do I protect my plants from frost in Pflugerville?
From about Nov 5 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 5 (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 5. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
