Loco, Oklahoma, sits in USDA hardiness zone 8a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
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 Loco, 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 Loco 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 Loco
Each reading below is measured for Loco itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredLoco runs about 248 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredLoco sits in USDA hardiness zone 8a.
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 Loco is in
Loco sits in the Cross Timbers — EPA Level III, inside the wider Great Plains. That is read at Loco's own centroid rather than borrowed from Stephens County.

Is it too late to plant in Loco?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Feb 15; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 15 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 18 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.

What an experienced grower watches for around here
In and around Loco, Underground Storage Tanks runs higher than the national average — 26 sites within ~10 miles of Loco. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
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 Loco
Everything above resolves to Loco as a whole — one PHZM band and one 28°F frost record, read across 168 acres. 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 Loco
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 Loco’s own record; 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 Loco
When does frost risk typically end in Loco?
The last hard freeze (28°F) in Loco typically lands around Mar 15, 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 Apr 5.
When is the first frost in Loco?
The first hard freeze (28°F) in Loco typically arrives around Nov 18, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 4, so the watching starts about Oct 19 — about 248 days after the spring freeze cleared.
How long is the growing season in Loco?
Measured between 28°F hard freezes, Loco sees about 248 frost-free days — roughly Mar 15 through Nov 18, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 5 to Nov 4, about 213 days.
Is the soil safe to grow vegetables in Loco?
The federal record around Loco is a meaningful one — 31 documented sites, mostly Underground Storage Tanks entries (26), the nearest Underground Storage Tanks 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 Loco?
From about Oct 19 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 18 (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 18. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Loco's scale — its 8a band and its 248-day season. Your yard writes its own version of Loco's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
