Clintondale, Pennsylvania, sits in USDA hardiness zone 6b — a zone band wide enough that plant choice, not possibility, is the interesting question.
On paper, cabbage, blackberry, california poppy, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Clintondale, no two yards are alike.

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

Season length
MeasuredClintondale runs about 192 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
MeasuredClintondale 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 Clintondale is in
Clintondale sits in the Ridge and Valley — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Clintondale's own centroid, and it is not what its county reads: Clinton County is mostly North Central Appalachians. The wider page above you is answering a different question about different ground.

Is it too late to plant in Clintondale?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Mar 23; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 20 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 29 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Clintondale, Nitrate runs higher than the national average — 92 sites within ~10 miles of Clintondale. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Clintondale
Everything above resolves to Clintondale as a whole — one PHZM band and one 28°F frost record, read across 246 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 Clintondale
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 Clintondale’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 Clintondale
When does frost risk typically end in Clintondale?
The last hard freeze (28°F) in Clintondale typically lands around Apr 20, 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 11.
When is the first frost in Clintondale?
The first hard freeze (28°F) in Clintondale typically arrives around Oct 29, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 15, so the watching starts about Sep 29 — about 192 days after the spring freeze cleared.
How long is the growing season in Clintondale?
Measured between 28°F hard freezes, Clintondale sees about 192 frost-free days — roughly Apr 20 through Oct 29, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 11 to Oct 15, about 157 days.
Is the soil safe to grow vegetables in Clintondale?
The federal record around Clintondale is a meaningful one — 309 documented sites, mostly Underground Storage Tanks entries (152), the nearest Underground Storage Tanks record about 0.2 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 Clintondale?
From about Sep 29 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 29 (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 29. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
