Citrus County, in Florida, sits in USDA hardiness zone 9b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Reliable performers under these conditions include mango, tomato, orange, and sweet potato; what your own ground favors still comes down to its soil, sun, and drainage.

Soil in Citrus County
Across Citrus County, the ground is predominantly Entisols, where Candler, Astatula, and Lake are the most extensive named soil series. The soil is generally excessively drained with a fine sand surface. Topsoil pH runs about 5.3–5.5, strongly acidic. Rainfall drains through hydrologic group A soils.

Growing Challenges in Florida
What an experienced grower plans around here — each one has a move.
Sandy soils drain too fast and hold few nutrients — frequent fertilization needed
Build organic matter relentlessly — compost and cover crops turn sand into soil that holds both water and food.
Humidity drives fungal diseases (powdery mildew, black spot, rust)
Space plants for airflow, water at the base in the morning, and choose resistant varieties — your extension office lists the proven ones.
Hurricane season (June-November) can destroy plantings
Favor wind-tough perennials, stake young trees properly, and keep fall crops in containers you can move ahead of a storm.
Nematodes are a serious pest in sandy FL soils
Summer solarization and crop-family rotation knock nematodes back — your extension office can confirm the species from a soil sample.
For cultivar selection, pest pressure, and planting-time guidance specific to Florida, the UF/IFAS Extension is the authoritative local source.
Safe to Grow Here?
What the federal record shows across Citrus County — and how to grow with it.
We checked the federal record across Citrus County — 500 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 Citrus 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 Citrus County, PFAS runs higher than the national average — 10 sites nearby. 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.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.

Frequently Asked Questions
What hardiness zone is Citrus County, Florida?
Citrus County sits in USDA hardiness zone 9b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
When does frost risk typically end in Citrus County?
Citrus County follows Florida's statewide frost window: last spring frost around Jan 1 - Mar 15 and first fall frost around Nov 15 - never (south FL), per NOAA 30-year climate normals (1991–2020). Frost dates shift with elevation and local microclimate, so watch your own site's cold pockets.
What vegetables grow in Citrus County?
Citrus County's zone 9b supports a wide range — strong performers include Mango, Tomato, Orange, Sweet Potato, and Banana. 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 Citrus County, really?
Officially, Citrus County sits in USDA zone 9b (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 Citrus County?
The federal record around Citrus County is a meaningful one — 500 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 Citrus County — what should I know before planting?
Start with three facts. Citrus County sits in USDA zone 9b, which sets what survives winter; the statewide frost window runs about Jan 1 - Mar 15 to Nov 15 - never (south FL) (NOAA 30-year climate normals); and 500 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.
