Lago Vista, Texas, sits in USDA hardiness zone 9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
Crops well matched to these conditions include artichoke, fig, california poppy, and cabbage — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Lago Vista, 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 Lago Vista 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 Lago Vista
Each reading below is measured for Lago Vista itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
From county recordsLago Vista runs about 299 days between hard freezes (read from Travis County, the closest normal to Lago Vista) — 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
MeasuredLago Vista 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 Lago Vista is in
Lago Vista sits in the Edwards Plateau — EPA Level III, inside the wider Great Plains. That is read at Lago Vista's own centroid rather than borrowed from Travis County.

Is it too late to plant in Lago Vista?
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. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

A note from Gnorman
What an experienced grower watches for around here
In and around Lago Vista, two things run higher than the national average within ~10 miles of Lago Vista — PFAS (6 sites) and Underground Storage Tanks (89 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 Lago Vista
Everything above resolves to Lago Vista as a whole — one PHZM band, read across 9K 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 Lago Vista
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 Lago Vista
When does frost risk typically end in Lago Vista?
The last hard freeze (28°F) in Lago Vista 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 Lago Vista?
The first hard freeze (28°F) in Lago Vista 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 Lago Vista?
Measured between 28°F hard freezes, Lago Vista 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 Lago Vista?
The federal record around Lago Vista is a meaningful one — 120 documented sites, mostly Underground Storage Tanks entries (89), the nearest Underground Storage Tanks record about 0.3 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 Lago Vista?
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.
