Sussex County, in Virginia, sits in USDA hardiness zone 7b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
The conditions favor tomato, grape, peanut, and dogwood, among others — though every individual site edits that list with its own soil, sun, and drainage.

Soil in Sussex County
Across Sussex County, the ground is predominantly Ultisols, where Slagle, Chastain, and Emporia are the most extensive named soil series. The soil is generally moderately well drained with a fine sandy loam surface. Topsoil pH runs about 4.6–4.8, very strongly acidic. Rainfall drains through hydrologic group C soils.

Is it too late to plant in Sussex 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 Jan 25; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 22 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 19 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.
Growing Challenges in Virginia
What an experienced grower plans around here — each one has a move.
Heavy Piedmont red clay requires amendment
Red clay turns from obstacle to asset with compost and time — and a raised bed lets you harvest while it happens.
Humidity and heat in summer promote disease
Space for airflow, water mornings at the base, and plant resistant varieties — your extension's humid-summer playbook.
Deer pressure is heavy in suburban and rural areas
A proper fence settles it; outside the fence, genuinely deer-resistant plants are the next best defense.
For cultivar selection, pest pressure, and planting-time guidance specific to Virginia, the Virginia Cooperative Extension is the authoritative local source.
Safe to Grow Here?
What the federal record shows across Sussex County — and how to grow with it.
We checked the federal record across Sussex County — 156 documented sites across 6 of the 9 source types we track.
The most significant on record: 1 Superfund site. 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 Sussex 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.

What an experienced grower watches for around here
In and around Sussex County, two things run higher than the national average — CAFO (3 sites) and Underground Storage Tanks (114 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.

Frequently Asked Questions
What hardiness zone is Sussex County, Virginia?
Sussex County sits in USDA hardiness zone 7b, 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 Sussex 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 Jan 25; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 22 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 19 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.
When does frost risk typically end in Sussex County?
The last hard freeze (28°F) in Sussex County typically lands around Feb 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 Sussex County?
Measured between 28°F hard freezes, Sussex County sees about 300 frost-free days — roughly Feb 22 through Dec 19, 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 Sussex County?
Sussex County's zone 7b supports a wide range — strong performers include Tomato, Grape, Peanut, Dogwood, 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 Sussex County, really?
Officially, Sussex County sits in USDA zone 7b (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 Sussex County?
The federal record around Sussex County is a meaningful one — 156 documented sites — 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.
Just moved to Sussex County — what should I know before planting?
Start with three facts. Sussex County sits in USDA zone 7b, which sets what survives winter; the last 28°F hard freeze typically clears around Feb 22, with about 300 frost-free days to work with (NOAA 1991–2020 climate normals); and 156 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.
