Tonkawa Tribal Housing, Oklahoma, sits in USDA hardiness zone 7a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Reliable performers under these conditions include cabbage, hazelnut, california poppy, and collard greens; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Tonkawa Tribal Housing, 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 Tonkawa Tribal Housing 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 Tonkawa Tribal Housing
Each reading below is measured for Tonkawa Tribal Housing itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredTonkawa Tribal Housing runs about 228 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.

Winter hardiness
MeasuredTonkawa Tribal Housing sits in USDA hardiness zone 7a.
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.

Is it too late to plant in Tonkawa Tribal Housing?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Feb 27; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 10 — long-season crops need about 90 days of runway, quick greens only 30. With a season this long, “too late” mostly means “switch crops” — second sowings and a full fall garden are the norm, with garlic closing the year.

A note from Gnorman
What an experienced grower watches for around here
In and around Tonkawa Tribal Housing, two things run higher than the national average within ~10 miles of Tonkawa Tribal Housing — Toxics Release Inventory (12 sites) and Underground Storage Tanks (90 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 Tonkawa Tribal Housing
Everything above resolves to Tonkawa Tribal Housing as a whole — one PHZM band and one 28°F frost record, read across 268 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 Tonkawa Tribal Housing
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 Tonkawa Tribal Housing’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.

Common questions about Tonkawa Tribal Housing
When does frost risk typically end in Tonkawa Tribal Housing?
The last hard freeze (28°F) in Tonkawa Tribal Housing typically lands around Mar 27, 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 17.
When is the first frost in Tonkawa Tribal Housing?
The first hard freeze (28°F) in Tonkawa Tribal Housing typically arrives around Nov 10, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 27, so the watching starts about Oct 11 — about 228 days after the spring freeze cleared.
How long is the growing season in Tonkawa Tribal Housing?
Measured between 28°F hard freezes, Tonkawa Tribal Housing sees about 228 frost-free days — roughly Mar 27 through Nov 10, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 17 to Oct 27, about 193 days.
Is the soil safe to grow vegetables in Tonkawa Tribal Housing?
The federal record around Tonkawa Tribal Housing is a meaningful one — 141 documented sites, mostly Underground Storage Tanks entries (90), the nearest Underground Storage Tanks record about 1.4 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 Tonkawa Tribal Housing?
From about Oct 11 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 10 (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 10. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
