Phillipsburg, 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.
Even in Phillipsburg, no two yards are alike.

What this means for growing in Phillipsburg
Each reading below is measured for Phillipsburg itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredPhillipsburg runs about 223 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
MeasuredPhillipsburg 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.
USDA PHZM 2023
The kind of country Phillipsburg is in
Phillipsburg sits in the Ozark Highlands — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Phillipsburg's own centroid rather than borrowed from Laclede County.

Is it too late to plant in Phillipsburg?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Feb 28; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 28 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 6 — long-season crops need about 90 days of runway, quick greens only 30. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.

What an experienced grower watches for around here
In and around Phillipsburg, Toxics Release Inventory runs higher than the national average — 3 sites within ~10 miles of Phillipsburg. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.

Your land is one point inside Phillipsburg
Everything above resolves to Phillipsburg as a whole — one PHZM band and one 28°F frost record, read across 510 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 Phillipsburg
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 Phillipsburg’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 Phillipsburg
When does frost risk typically end in Phillipsburg?
The last hard freeze (28°F) in Phillipsburg typically lands around Mar 28, 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 18.
When is the first frost in Phillipsburg?
The first hard freeze (28°F) in Phillipsburg typically arrives around Nov 6, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 23, so the watching starts about Oct 7 — about 223 days after the spring freeze cleared.
How long is the growing season in Phillipsburg?
Measured between 28°F hard freezes, Phillipsburg sees about 223 frost-free days — roughly Mar 28 through Nov 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 18 to Oct 23, about 188 days.
Is the soil safe to grow vegetables in Phillipsburg?
The federal record around Phillipsburg shows 46 documented sites, mostly Underground Storage Tanks entries (26), the nearest Underground Storage Tanks record about 0.3 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Phillipsburg?
From about Oct 7 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 6 (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 6. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
