Is it too late to plant in Moniteau County?

For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 9; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 26 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

Growing Challenges in Missouri

What an experienced grower plans around here — each one has a move.

Highly variable weather with late frosts and early heat

Let your local frost normals call the plantings — Missouri springs punish the calendar-planters and reward the patient.

Heavy clay soils in many regions

Raised beds solve clay drainage the first weekend — and yearly compost turns the ground under them into loam.

Ozark soils are thin and rocky

One soil test shows what thin Ozark ground actually holds — then build up with compost or beds where the depth runs out.

Safe to Grow Here?

What the federal record shows across Moniteau County — and how to grow with it.

Federal record: High

We checked the federal record across Moniteau County174 documented sites across 8 of the 9 source types we track.

The most significant on record: 2 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.

Moniteau County carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

A note from Gnorman

What an experienced grower watches for around here

In and around Moniteau County, two things run higher than the national average — Mining (71 sites) and CAFO (10 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.

Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.

CAFO: CAFOs pose a different contamination profile than chemical sources.

Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.

Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.

Frequently Asked Questions

What hardiness zone is Moniteau County, Missouri?

Moniteau County sits in USDA hardiness zone 6b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.

Is it too late to plant in Moniteau County?

For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 9; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 26 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

When does frost risk typically end in Moniteau County?

The last hard freeze (28°F) in Moniteau County typically lands around Mar 9, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.

How long is the growing season in Moniteau County?

Measured between 28°F hard freezes, Moniteau County sees about 262 frost-free days — roughly Mar 9 through Nov 26, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.

What vegetables grow in Moniteau County?

Moniteau County's zone 6b supports a wide range — strong performers include Tomato, Peach, Grape, Dogwood, and Blackberry. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.

Which hardiness zone is Moniteau County, really?

Officially, Moniteau County sits in USDA zone 6b (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.

Is the soil safe to grow vegetables in Moniteau County?

The federal record around Moniteau County runs heavier than most — 174 documented sites — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.

Just moved to Moniteau County — what should I know before planting?

Start with three facts. Moniteau County sits in USDA zone 6b, which sets what survives winter; the last 28°F hard freeze typically clears around Mar 9, with about 262 frost-free days to work with (NOAA 1991–2020 climate normals); and 174 documented sites sit on the federal record here, so a soil test before food beds is the smart first step. From there, matching plants to your actual soil and sun is the fun part.
