Perry County, in Indiana, sits in USDA hardiness zone 6b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Reliable performers under these conditions include tomato, sweet corn, pawpaw, and peony; what your own ground favors still comes down to its soil, sun, and drainage.

Is it too late to plant in Perry County?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Feb 5; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 27 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.
Growing Challenges in Indiana
What an experienced grower plans around here — each one has a move.
Heavy clay soils limit drainage in many areas
Mounded rows and compost open clay up — and where water still stands, a raised bed ends the argument.
Late spring frosts through early May
Hold tender transplants until your local last-frost normal clears — hardy greens will happily take the early slot.
Hot humid summers promote blight and mildew
Mulch to stop soil splash, water at the base, and rotate crop families — the blight playbook your extension teaches.

Frequently Asked Questions
What hardiness zone is Perry County, Indiana?
Perry County sits in USDA hardiness zone 6b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
Is it too late to plant in Perry County?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. Cool-season crops can go in from around Feb 5; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 27 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.
When does frost risk typically end in Perry County?
The last hard freeze (28°F) in Perry County typically lands around Mar 5, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
How long is the growing season in Perry County?
Measured between 28°F hard freezes, Perry County sees about 267 frost-free days — roughly Mar 5 through Nov 27, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.
What vegetables grow in Perry County?
Perry County's zone 6b supports a wide range — strong performers include Tomato, Sweet Corn, Pawpaw, Peony, and Apple. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is Perry County, really?
Officially, Perry County sits in USDA zone 6b (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in Perry County?
The federal record around Perry County shows 139 documented sites — 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.
Just moved to Perry County — what should I know before planting?
Start with three facts. Perry County sits in USDA zone 6b, which sets what survives winter; the last 28°F hard freeze typically clears around Mar 5, with about 267 frost-free days to work with (NOAA 1991–2020 climate normals); and 139 documented sites sit on the federal record — a typical footprint for a growing area, worth a look on the contamination map before food beds. From there, matching plants to your actual soil and sun is the fun part.
