East Randolph, New York, sits in USDA hardiness zone 5b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
The conditions favor cabbage, cranberry, lavender, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in East Randolph, no two yards are alike.

What this means for growing in East Randolph
Each reading below is measured for East Randolph itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredEast Randolph runs about 178 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.

Winter hardiness
MeasuredEast Randolph sits in USDA hardiness zone 5b.
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 East Randolph is in
East Randolph sits in the Northern Allegheny Plateau — EPA Level III, inside the wider Eastern Temperate Forests. That is read at East Randolph's own centroid, and it is not what its county reads: Cattaraugus County is mostly North Central Appalachians. The wider page above you is answering a different question about different ground.
What Grows in East Randolph
Every plant below cleared East Randolph's own zone 5b and its 178-day season. Each card opens that plant's New York profile. How we score.






























Is it too late to plant in East Randolph?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Apr 2; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 30 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 25 — long-season crops need about 90 days of runway, quick greens only 30. Late in the year the fall bench takes over — quick greens, radishes, and garlic that repays you next summer.

A note from Gnorman
What an experienced grower watches for around here
In and around East Randolph, CAFO runs higher than the national average — 9 sites within ~10 miles of East Randolph. That's not a problem with your land — it's information about it.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.

Your land is one point inside East Randolph
Everything above resolves to East Randolph as a whole — one PHZM band and one 28°F frost record, read across 710 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 East Randolph
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 East Randolph’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 East Randolph
When does frost risk typically end in East Randolph?
The last hard freeze (28°F) in East Randolph typically lands around Apr 30, 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 May 21.
When is the first frost in East Randolph?
The first hard freeze (28°F) in East Randolph typically arrives around Oct 25, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 11, so the watching starts about Sep 25 — about 178 days after the spring freeze cleared.
How long is the growing season in East Randolph?
Measured between 28°F hard freezes, East Randolph sees about 178 frost-free days — roughly Apr 30 through Oct 25, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 21 to Oct 11, about 143 days.
Is the soil safe to grow vegetables in East Randolph?
The federal record around East Randolph is a meaningful one — 106 documented sites, mostly Underground Storage Tanks entries (40), the nearest Brownfields record about 0.5 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in East Randolph?
From about Sep 25 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 Oct 25 (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 Oct 25. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
