What this means for growing in Newburgh Heights
Each reading below is measured for Newburgh Heights itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredNewburgh Heights runs about 237 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
MeasuredNewburgh Heights sits in USDA hardiness zone 6b.
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 Newburgh Heights is in
Newburgh Heights sits in the Eastern Great Lakes Lowlands — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Newburgh Heights's own centroid, and it is not what its county reads: Cuyahoga County is mostly Erie Drift Plain. The wider page above you is answering a different question about different ground.

Is it too late to plant in Newburgh Heights?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Mar 2; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 30 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 22 — long-season crops need about 90 days of runway, quick greens only 30. With a season this long, “too late” mostly means “switch crops” — second sowings and a full fall garden are the norm, with garlic closing the year.

What an experienced grower watches for around here
In and around Newburgh Heights, two things run higher than the national average within ~10 miles of Newburgh Heights — Toxics Release Inventory (383 sites) and Superfund (60 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside Newburgh Heights
Everything above resolves to Newburgh Heights as a whole — one PHZM band and one 28°F frost record, read across 372 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 Newburgh Heights
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 Newburgh Heights’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 Newburgh Heights
When does frost risk typically end in Newburgh Heights?
The last hard freeze (28°F) in Newburgh Heights typically lands around Mar 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 Apr 20.
When is the first frost in Newburgh Heights?
The first hard freeze (28°F) in Newburgh Heights typically arrives around Nov 22, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 8, so the watching starts about Oct 23 — about 237 days after the spring freeze cleared.
How long is the growing season in Newburgh Heights?
Measured between 28°F hard freezes, Newburgh Heights sees about 237 frost-free days — roughly Mar 30 through Nov 22, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 20 to Nov 8, about 202 days.
Is the soil safe to grow vegetables in Newburgh Heights?
The federal record around Newburgh Heights is a meaningful one — 3,995 documented sites, mostly Underground Storage Tanks entries (2,170), the nearest Underground Storage Tanks record under a tenth of a mile 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 Newburgh Heights?
From about Oct 23 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 Nov 22 (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 Nov 22. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
