Is it too late to plant in Lyon Mountain?
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 30; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 24 — long-season crops need about 90 days of runway, quick greens only 30. The tail of the season still works: sixty-day crops into late summer, quick greens after, garlic last of all.

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.

What an experienced grower watches for around here
In and around Lyon Mountain, Nitrate runs higher than the national average — 26 sites nearby. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.

Frequently Asked Questions
What hardiness zone is Lyon Mountain, New York?
Lyon Mountain sits in USDA hardiness zones 4a-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 Lyon Mountain?
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 30; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 24 — long-season crops need about 90 days of runway, quick greens only 30. The tail of the season still works: sixty-day crops into late summer, quick greens after, garlic last of all.
When does frost risk typically end in Lyon Mountain?
The last hard freeze (28°F) in Lyon Mountain typically lands around Apr 27, 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.
When is the first frost in Lyon Mountain?
The first hard freeze (28°F) in Lyon Mountain typically arrives around Oct 24, per NOAA 1991–2020 climate normals — the point most tender summer crops finish. Lighter frosts usually reach a couple of weeks earlier, so watch the forecast from late summer on and harvest or cover tender plants before the first cold night.
What vegetables grow in Lyon Mountain?
Lyon Mountain's zones 4a-5b support 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 Lyon Mountain, really?
Officially, Lyon Mountain sits in USDA zones 4a-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 Lyon Mountain?
The federal record around Lyon Mountain shows 64 documented sites — 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 Lyon Mountain?
As the season closes around the first 28°F hard freeze near Oct 24 (NOAA 1991–2020 climate normals), a few moves buy time: cover tender plants with floating row cover or an old sheet on still, clear nights, water the soil the afternoon before a freeze so it holds warmth overnight, and harvest frost-tender crops like tomatoes, peppers, and basil before the first hard night. Hardy greens and root crops shrug off light frost and often sweeten after it, so leave them in.
