Soil in Montgomery County
Across Montgomery County, the ground is predominantly Alfisols, where Lansing, Darien, and Burdett are the most extensive named soil series. The soil is generally somewhat poorly drained with a silt loam surface. Topsoil pH runs about 5.9–6.5, slightly acidic. Rainfall drains through hydrologic group C/D soils.

Is it too late to plant in Montgomery County?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Mar 15; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 12 (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. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.
Growing Challenges in New York
What an experienced grower plans around here — each one has a move.
Short upstate growing season (100-140 frost-free days in Adirondacks)
Fast varieties plus season extension: a low tunnel or cold frame reliably buys back the missing weeks.
Heavy clay soils in western NY require drainage improvement
A raised bed solves the drainage the first season; long-term, steady compost works that clay into excellent loam.
Late spring frosts through May in higher elevations
Plant to your elevation's real frost dates, not the valley's — two weeks of patience saves a full replanting.
Deer browse pressure is heavy in suburban and rural areas
Fencing is the control that works; behind it, aromatic herbs, ferns, and daffodils are the plants deer tend to pass by.
For cultivar selection, pest pressure, and planting-time guidance specific to New York, the Cornell Cooperative Extension is the authoritative local source.
Safe to Grow Here?
What the federal record shows across Montgomery County — and how to grow with it.
We checked the federal record across Montgomery County — 487 documented sites across 8 of the 9 source types we track.
The most significant on record: 9 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Montgomery 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 Montgomery County, two things run higher than the national average — CAFO (19 sites) and Superfund (9 sites). That's not a problem with your land — it's information about it.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Frequently Asked Questions
What hardiness zone is Montgomery County, New York?
Montgomery County sits in USDA hardiness zone 5b, 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 Montgomery County?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Mar 15; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 12 (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. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.
When does frost risk typically end in Montgomery County?
The last hard freeze (28°F) in Montgomery County typically lands around Apr 12, 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 Montgomery County?
Measured between 28°F hard freezes, Montgomery County sees about 212 frost-free days — roughly Apr 12 through Nov 10, 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 Montgomery County?
Montgomery County's zone 5b supports a wide range — strong performers include Apple, Garlic, Kale, Sugar Maple, and Blueberry. 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 Montgomery County, really?
Officially, Montgomery County sits in USDA zone 5b (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 Montgomery County?
The federal record around Montgomery County runs heavier than most — 487 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 Montgomery County — what should I know before planting?
Start with three facts. Montgomery County sits in USDA zone 5b, which sets what survives winter; the last 28°F hard freeze typically clears around Apr 12, with about 212 frost-free days to work with (NOAA 1991–2020 climate normals); and 487 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.
