What this means for growing in Jeffersonville

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

Season length

Measured

Jeffersonville runs about 172 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.

Buying weeks at each end

NOAA 1991–2020 Climate Normals

Winter hardiness

Measured

Jeffersonville sits in USDA hardiness zone 6a.

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 Jeffersonville is in

Jeffersonville sits in the Northern Allegheny Plateau — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Jeffersonville's own centroid rather than borrowed from Sullivan County.

Is it too late to plant in Jeffersonville?

Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Mar 31; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 28 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 17 — long-season crops need about 90 days of runway, quick greens only 30. Even past midsummer there is room for a true fall garden here, and garlic planted near the close carries the momentum into next year.

A note from Gnorman

What an experienced grower watches for around here

In and around Jeffersonville, two things run higher than the national average within ~10 miles of Jeffersonville — CAFO (8 sites) and Underground Storage Tanks (133 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.

CAFO: CAFOs pose a different contamination profile than chemical sources.

Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.

Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.

Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Jeffersonville

Everything above resolves to Jeffersonville as a whole — one PHZM band and one 28°F frost record, read across 261 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 Jeffersonville

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 Jeffersonville’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 Jeffersonville

When does frost risk typically end in Jeffersonville?

The last hard freeze (28°F) in Jeffersonville typically lands around Apr 28, 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 19.

When is the first frost in Jeffersonville?

The first hard freeze (28°F) in Jeffersonville typically arrives around Oct 17, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 3, so the watching starts about Sep 17 — about 172 days after the spring freeze cleared.

How long is the growing season in Jeffersonville?

Measured between 28°F hard freezes, Jeffersonville sees about 172 frost-free days — roughly Apr 28 through Oct 17, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 19 to Oct 3, about 137 days.

Is the soil safe to grow vegetables in Jeffersonville?

The federal record around Jeffersonville shows 192 documented sites, mostly Underground Storage Tanks entries (133), the nearest Underground Storage Tanks record about 0.2 miles out — 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 Jeffersonville?

From about Sep 17 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 17 (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 17. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.

Everything above is measured at Jeffersonville's scale — its 6a band and its 172-day season. Your yard writes its own version of Jeffersonville's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
