Alvarado, Texas, sits in USDA hardiness zone 8b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Crops well matched to these conditions include cabbage, fig, california poppy, and collard greens — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Alvarado, 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 Alvarado 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 Alvarado
Each reading below is measured for Alvarado itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsAlvarado runs about 283 days between hard freezes (read from Johnson County, the closest normal to Alvarado) — 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
MeasuredAlvarado sits in USDA hardiness zone 8b.
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 Alvarado is in
Alvarado sits in the Cross Timbers — EPA Level III, inside the wider Great Plains. That is read at Alvarado's own centroid rather than borrowed from Johnson County.

Is it too late to plant in Alvarado?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 23; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 20 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 30 — 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 Alvarado, two things run higher than the national average within ~10 miles of Alvarado — PFAS (7 sites) and Toxics Release Inventory (17 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.
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 Alvarado
Everything above resolves to Alvarado as a whole — one PHZM band, read across 4K acres, with hard-freeze dates borrowed from Johnson 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 Alvarado
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 Johnson 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 Alvarado
When does frost risk typically end in Alvarado?
The last hard freeze (28°F) in Alvarado typically lands around Feb 20, 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 13.
When is the first frost in Alvarado?
The first hard freeze (28°F) in Alvarado typically arrives around Nov 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 16, so the watching starts about Oct 31 — about 283 days after the spring freeze cleared.
How long is the growing season in Alvarado?
Measured between 28°F hard freezes, Alvarado sees about 283 frost-free days — roughly Feb 20 through Nov 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 13 to Nov 16, about 248 days.
Is the soil safe to grow vegetables in Alvarado?
The federal record around Alvarado is a meaningful one — 191 documented sites, mostly Underground Storage Tanks entries (133), the nearest Underground Storage Tanks record about 0.2 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 Alvarado?
From about Oct 31 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 Nov 30 (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 Nov 30. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
