Woodson Terrace, Missouri, sits in USDA hardiness zone 7a — a zone band wide enough that plant choice, not possibility, is the interesting question.
These conditions suit cabbage, hazelnut, california poppy, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

What this means for growing in Woodson Terrace
Each reading below is measured for Woodson Terrace itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredWoodson Terrace runs about 247 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
MeasuredWoodson Terrace 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.

The kind of country Woodson Terrace is in

Is it too late to plant in Woodson Terrace?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Feb 18; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 20 — 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.

Your land is one point inside Woodson Terrace
Everything above resolves to Woodson Terrace as a whole — one PHZM band and one 28°F frost record, read across 496 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 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 Woodson Terrace
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 Woodson Terrace’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 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.

Common questions about Woodson Terrace
When does frost risk typically end in Woodson Terrace?
The last hard freeze (28°F) in Woodson Terrace typically lands around Mar 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 Apr 8.
When is the first frost in Woodson Terrace?
The first hard freeze (28°F) in Woodson Terrace typically arrives around Nov 20, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 6, so the watching starts about Oct 21 — about 247 days after the spring freeze cleared.
How long is the growing season in Woodson Terrace?
Measured between 28°F hard freezes, Woodson Terrace sees about 247 frost-free days — roughly Mar 18 through Nov 20, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 8 to Nov 6, about 212 days.
Is the soil safe to grow vegetables in Woodson Terrace?
The federal record around Woodson Terrace is a meaningful one — 3,514 documented sites, mostly Underground Storage Tanks entries (2,128), the nearest Underground Storage Tanks record about 0.1 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 Woodson Terrace?
From about Oct 21 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 20 (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 20. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
