Pulaski County, in Virginia, sits in USDA hardiness zone 7a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
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.
Pulaski County lies within Appalachia — a regional growing area with its own character.

Heat in Pulaski County
Across a year, Pulaski County accumulates about 2,980 growing degree days above 50°F, about 754 fewer than the middle Virginia county — ahead of 12 of Virginia’s 133 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.

Soil in Pulaski County
Across Pulaski County, the ground is predominantly Ultisols, where Berks, Groseclose, and Gilpin are the most extensive named soil series. The soil is generally well drained with a silt loam surface. Topsoil pH runs about 4.6–5.5, very strongly acidic. Rainfall drains through hydrologic group B soils.

How the ground varies across Pulaski County
The USDA soil survey maps 77% of Pulaski County as well drained — but another 18% drains differently: 11% somewhat excessively drained, 6% moderately well drained.
Berks is the most extensive named soil at 12% of mapped acres, then Groseclose (9%) and Gilpin (8%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Pulaski County
Each reading below is measured for Pulaski County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Pulaski County are well drained, in hydrologic group B — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Pulaski County runs about pH 4.6–5.5, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Season length
MeasuredPulaski County runs about 206 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
MeasuredPulaski County 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.

The kind of country Pulaski County is in
Pulaski County spans 2 EPA Level III ecoregions — Ridge and Valley (83%) and Blue Ridge (17%). Which one your land falls in changes what grows wild there and how the ground behaves, and a county-wide answer cannot tell you which.
What Grows in Pulaski County
We scored all 1,086 plants against Pulaski County's own USDA zone 7a and its own 206-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Virginia profile.
Is it too late to plant in Pulaski County?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Mar 7; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 4 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 27 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.

What the federal record shows across Pulaski County — and how to grow with it.
We checked the federal record across Pulaski County — 268 documented sites across 7 of the 9 source types we track.
The most significant on record: 3 Superfund sites (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Pulaski County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

What an experienced grower watches for around here
In and around Pulaski County, two things run higher than the national average across Pulaski County — PFAS (3 sites) and Toxics Release Inventory (22 sites). That's not a problem with your land — it's information about it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Your land is one point inside Pulaski County
Everything above resolves to Pulaski County as a whole — one PHZM band and one county frost record, read across 205K 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 county 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 county average.

How we know this about Pulaski County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Pulaski County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Pulaski County
When does frost risk typically end in Pulaski County?
The last hard freeze (28°F) in Pulaski County typically lands around Apr 4, 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 25.
How long is the growing season in Pulaski County?
Measured between 28°F hard freezes, Pulaski County sees about 206 frost-free days — roughly Apr 4 through Oct 27, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 25 to Oct 13, about 171 days.
Is the soil safe to grow vegetables in Pulaski County?
The federal record around Pulaski County is a meaningful one — 268 documented sites, mostly Underground Storage Tanks entries (178), the nearest Brownfields record about 0.5 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.
