Every figure names the dataset it came from. Hard-freeze dates are county 28°F normals: light frosts run a few weeks past them, and tender transplants usually wait 2–3 weeks after the last hard freeze.

Heat in Schuyler County
Across a year, Schuyler County accumulates about 3,208 growing degree days above 50°F, about 545 fewer than the middle Missouri county — ahead of 3 of Missouri’s 115 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.

Soil in Schuyler County
Across Schuyler County, the ground is predominantly Alfisols, where Gara, Winnegan, and Armstrong are the most extensive named soil series. The soil is generally somewhat poorly drained with a loam surface. Topsoil pH runs about 5.9–6.8, slightly acidic. Rainfall drains through hydrologic group D soils.

How the ground varies across Schuyler County
The USDA soil survey maps 32% of Schuyler County as somewhat poorly drained — but another 68% drains differently: 31% moderately well drained, 20% poorly drained.
Gara is the most extensive named soil at 25% of mapped acres, then Winnegan (15%) and Armstrong (15%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Schuyler County
Each reading below is measured for Schuyler County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Schuyler County are somewhat poorly drained, in hydrologic group D — ground that sheds water slowly.
Beds can stay saturated for days after heavy rain, and the roots of most vegetables, berries, and fruit trees suffocate or rot in soil that never drains.
Raised beds or mounded rows lift roots above the wet zone; choose water-tolerant crops for the lowest spots.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Schuyler County runs about pH 5.9–6.8, close to neutral.
This is the range most vegetables prefer — one correction you probably do not have to make, which is genuinely good news for a new bed.
Keep it there with compost rather than lime or sulfur, and only amend if your own soil test says otherwise.
USDA NRCS SSURGO
Season length
MeasuredSchuyler County runs about 207 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
MeasuredSchuyler County sits in USDA hardiness zone 6a.
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 Schuyler County is in
Schuyler County sits in the Central Irregular Plains — EPA Level III, inside the wider Great Plains. One consistent ecological setting across the whole county.
What Grows in Schuyler County
We scored all 1,086 plants against Schuyler County's own USDA zone 6a and its own 207-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Missouri profile.
Is it too late to plant in Schuyler County?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Mar 9; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 6 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 30 — 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 gets applied to farmland in Schuyler County
USGS estimates 48,044 lb of Glyphosate on Schuyler County farmland in 2019, its largest by weight, ahead of Metolachlor & Metolachlor-s (17,662 lb) and Atrazine (12,499 lb).

Safe to Grow Here?
What the federal record shows across Schuyler County — and how to grow with it.
We checked the federal record across Schuyler County — 20 documented sites across 5 of the 9 source types we track.
The most significant on record: 1 concentrated animal feeding operation. Large-scale animal operations that can contaminate soil and groundwater with nitrates and pathogens.
The federal record across Schuyler County is a modest one — a typical footprint for a growing area. Nothing here calls for alarm; it's worth knowing which recorded sites sit closest to where you grow, and each one on the map carries its type and location. If one turns out to be a near neighbor, a one-time soil test settles the question.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

Your land is one point inside Schuyler County
Everything above resolves to Schuyler County as a whole — one PHZM band and one county frost record, read across 197K 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 county 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 county average.

How we know this about Schuyler County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Schuyler County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Schuyler County
When does frost risk typically end in Schuyler County?
The last hard freeze (28°F) in Schuyler County typically lands around Apr 6, 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 27.
How long is the growing season in Schuyler County?
Measured between 28°F hard freezes, Schuyler County sees about 207 frost-free days — roughly Apr 6 through Oct 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 27 to Oct 16, about 172 days.
Is the soil safe to grow vegetables in Schuyler County?
The federal record around Schuyler County shows 20 documented sites, mostly Underground Storage Tanks entries (12), the nearest Underground Storage Tanks record about 3.2 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.
