Whitehouse, Texas, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
These conditions suit cabbage, fig, california poppy, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Even in Whitehouse, no two yards are alike.

What this means for growing in Whitehouse
Each reading below is measured for Whitehouse itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsWhitehouse runs about 286 days between hard freezes (read from Smith County, the closest normal to Whitehouse) — 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
MeasuredWhitehouse 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 Whitehouse is in
Whitehouse sits in the South Central Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Whitehouse's own centroid rather than borrowed from Smith County.

Is it too late to plant in Whitehouse?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 1 — 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 Whitehouse, Underground Storage Tanks runs higher than the national average — 298 sites within ~10 miles of Whitehouse. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
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 Whitehouse
Everything above resolves to Whitehouse as a whole — one PHZM band, read across 4K acres, with hard-freeze dates borrowed from Smith 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 Whitehouse
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 Smith 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 Whitehouse
When does frost risk typically end in Whitehouse?
The last hard freeze (28°F) in Whitehouse typically lands around Feb 18, 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 11.
When is the first frost in Whitehouse?
The first hard freeze (28°F) in Whitehouse typically arrives around Dec 1, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 17, so the watching starts about Nov 1 — about 286 days after the spring freeze cleared.
How long is the growing season in Whitehouse?
Measured between 28°F hard freezes, Whitehouse sees about 286 frost-free days — roughly Feb 18 through Dec 1, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 11 to Nov 17, about 251 days.
Is the soil safe to grow vegetables in Whitehouse?
The federal record around Whitehouse is a meaningful one — 373 documented sites, mostly Underground Storage Tanks entries (298), the nearest PFAS record under a tenth of a mile 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 Whitehouse?
From about Nov 1 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 1 (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 1. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
