Garrett, Texas, sits in USDA hardiness zone 8b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
On paper, cabbage, fig, california poppy, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Garrett, no two yards are alike.

What this means for growing in Garrett
Each reading below is measured for Garrett itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsGarrett runs about 285 days between hard freezes (read from Ellis County, the closest normal to Garrett) — 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
MeasuredGarrett 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 Garrett is in
Garrett sits in the Texas Blackland Prairies — EPA Level III, inside the wider Great Plains. That is read at Garrett's own centroid rather than borrowed from Ellis County.

Is it too late to plant in Garrett?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Jan 20; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 17 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 29 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

What an experienced grower watches for around here
In and around Garrett, two things run higher than the national average within ~10 miles of Garrett — Toxics Release Inventory (26 sites) and Underground Storage Tanks (151 sites). That's not a problem with your land — it's information about it.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Garrett
Everything above resolves to Garrett as a whole — one PHZM band, read across 1K acres, with hard-freeze dates borrowed from Ellis 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 Garrett
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 Ellis 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 Garrett
When does frost risk typically end in Garrett?
The last hard freeze (28°F) in Garrett typically lands around Feb 17, 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 10.
When is the first frost in Garrett?
The first hard freeze (28°F) in Garrett typically arrives around Nov 29, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 15, so the watching starts about Oct 30 — about 285 days after the spring freeze cleared.
How long is the growing season in Garrett?
Measured between 28°F hard freezes, Garrett sees about 285 frost-free days — roughly Feb 17 through Nov 29, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 10 to Nov 15, about 250 days.
Is the soil safe to grow vegetables in Garrett?
The federal record around Garrett is a meaningful one — 209 documented sites, mostly Underground Storage Tanks entries (151), the nearest Underground Storage Tanks record about 0.5 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 Garrett?
From about Oct 30 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 29 (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 29. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
