Lake Wynonah, Pennsylvania, sits in USDA hardiness zone 7a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
The conditions favor cabbage, pawpaw, california poppy, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Lake Wynonah, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Lake Wynonah lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Lake Wynonah
Each reading below is measured for Lake Wynonah itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredLake Wynonah runs about 202 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
MeasuredLake Wynonah sits in USDA hardiness zone 7a.
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.
USDA PHZM 2023
The kind of country Lake Wynonah is in
Lake Wynonah sits in the Ridge and Valley — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Lake Wynonah's own centroid rather than borrowed from Schuylkill County.

Is it too late to plant in Lake Wynonah?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Mar 12; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 9 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 28 — long-season crops need about 90 days of runway, quick greens only 30. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.

What an experienced grower watches for around here
In and around Lake Wynonah, CAFO runs higher than the national average — 24 sites within ~10 miles of Lake Wynonah. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
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 Lake Wynonah
Everything above resolves to Lake Wynonah as a whole — one PHZM band and one 28°F frost record, read across 2K 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 Lake Wynonah
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 Lake Wynonah’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 Lake Wynonah
When does frost risk typically end in Lake Wynonah?
The last hard freeze (28°F) in Lake Wynonah typically lands around Apr 9, 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 30.
When is the first frost in Lake Wynonah?
The first hard freeze (28°F) in Lake Wynonah typically arrives around Oct 28, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 14, so the watching starts about Sep 28 — about 202 days after the spring freeze cleared.
How long is the growing season in Lake Wynonah?
Measured between 28°F hard freezes, Lake Wynonah sees about 202 frost-free days — roughly Apr 9 through Oct 28, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 30 to Oct 14, about 167 days.
Is the soil safe to grow vegetables in Lake Wynonah?
The federal record around Lake Wynonah is a meaningful one — 511 documented sites, mostly Underground Storage Tanks entries (279), the nearest Nitrate record about 1.6 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 Lake Wynonah?
From about Sep 28 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 28 (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 28. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
