Is it too late to plant in Cumberland 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 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 22 (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. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.
Growing Challenges in Pennsylvania
What an experienced grower plans around here — each one has a move.
Rocky shale soils in the ridge-and-valley region
Build up over shale rather than into it — raised beds with imported soil give roots depth the ridge won't.
Short mountain seasons in the Poconos and Alleghenies
Mountain growers stretch the season with cold frames and fast varieties — the missing weeks are recoverable.
Deer pressure is among the highest in the US
In the hardest-hit deer country, a tall fence is the only reliable line — resistant plants cover the rest.
For cultivar selection, pest pressure, and planting-time guidance specific to Pennsylvania, the Penn State Extension is the authoritative local source.

What the federal record shows across Cumberland County — and how to grow with it.
We checked the federal record across Cumberland County — 1,407 documented sites across 8 of the 9 source types we track.
The most significant on record: 3 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Cumberland County carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

What an experienced grower watches for around here
In and around Cumberland County, CAFO runs higher than the national average — 15 sites nearby. 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.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.

Frequently Asked Questions
What hardiness zone is Cumberland County, Pennsylvania?
Cumberland County sits in USDA hardiness zone 7a, 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 Cumberland 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 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 22 (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. There is slack in a calendar like this — late plantings, second rounds of favorites, and a fall bench that keeps beds working.
When does frost risk typically end in Cumberland County?
The last hard freeze (28°F) in Cumberland County typically lands around Mar 22, 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 Cumberland County?
Measured between 28°F hard freezes, Cumberland County sees about 250 frost-free days — roughly Mar 22 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 Cumberland County?
Cumberland County's zone 7a supports a wide range — strong performers include Apple, Tomato, Grape, Mountain Laurel, and Mushroom. 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 Cumberland County, really?
Officially, Cumberland County sits in USDA zone 7a (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 Cumberland County?
The federal record around Cumberland County runs heavier than most — 1,407 documented sites — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
Just moved to Cumberland County — what should I know before planting?
Start with three facts. Cumberland County sits in USDA zone 7a, which sets what survives winter; the last 28°F hard freeze typically clears around Mar 22, with about 250 frost-free days to work with (NOAA 1991–2020 climate normals); and 1,407 documented sites sit on the federal record here, so a soil test before food beds is the smart first step. From there, matching plants to your actual soil and sun is the fun part.
