Your yard isn't the whole zone.
Cilantro is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is. A typical Tennessee site runs ~230 frost-free days, but that is a state median, not your yard: slope, trees, and low spots move the last-frost date across a single parcel. Enter your address and we'll score cilantro against your land's actual frost dates, sun, and soil.

Tennessee is not one climate
A single Tennessee answer averages 95 counties whose growing seasons are 73 days apart — from 193 frost-free days in Johnson County to 266 in Shelby County. Which end of that your land sits nearer changes what cilantro can finish before the first hard freeze.
The middle half of 95 counties runs 221–235 days, with a median of 230 days — a 73-day span end to end.

When to Plant Cilantro in Tennessee
The frost window
Across Tennessee, the last spring hard freeze (28°F) clears between Mar 21 and Mar 29, and the first fall hard freeze lands between Nov 5 and Nov 12 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 221-day window you can count on — up to 236 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Frost tenderness
Cilantro is frost-tender — FAO ECOCROP puts its killing temperature at 32°F — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does. That is the point where cold damages growing tissue, not a winter-survival floor — an established perennial comes through far colder while dormant, which is what its hardiness zone tells you.
When to start the seed
Cilantro is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — Tennessee's dates above are the whole calendar for it. That makes the last-freeze date the binding constraint, and a warmer pocket of your own yard is worth more to this crop than it is to a transplanted one.
Days to maturity vs. the window
At 50 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 171 days to spare even in Tennessee's tightest freeze scenario — room for a later start or a second sowing.
Timing tuned to sub-state frost dates — Johnson County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says cilantro survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Cilantro wants 35+ frost-free days; a typical Tennessee site sees ~230 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Cilantro needs ~700 GDD (base 50°F) to ripen. The state median runs ~4122 GDD (from PRISM 1991-2020 climate normals), so Tennessee's typical season clears that easily.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Cilantro tolerates a wide pH range (pH 4-8) — 4 units, acid ground through alkaline — so soil acidity is rarely what limits it in Tennessee. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5.5 and 7.5 — worth knowing before you decide whether a Tennessee soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Tennessee site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
Tennessee's soils run mostly silt loam, but SSURGO maps the series, texture, and drainage under your exact parcel. Cilantro needs about 19 inches of workable depth, so it is that horizon — not the surface — you are testing for. That map unit, not the state average, decides how cilantro performs.

Before you plant cilantro for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before cilantro goes in. What follows is Tennessee’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Tennessee — and how to grow with it.
We checked the federal record across Tennessee — 28,130 documented sites across 8 of the 9 source types we track.
The most significant on record: 321 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Tennessee 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 Tennessee, two things run higher than the national average across Tennessee — PFAS (262 sites) and Toxics Release Inventory (1,955 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.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Cilantro in Tennessee
Zone compatibility tells you about winter cold survival — but Tennessee growers also need to think about:
Heavy clay soils in the Nashville Basin
High humidity promotes disease in summer
Variable spring weather with late frost risk
Growing cilantro here specifically
Cilantro wants pH 4.0–8.0 and rates to USDA zones 2–11, but Tennessee's soils are dominantly silt loam — the fit is decided by your parcel's own map unit, not the state average.
Match cilantro to your parcel's SSURGO map unit — test pH and texture, and amend toward its 4.0–8.0 range. How to handle it →
What to actually do about these — and the constraints that apply to every Tennessee grower, not just cilantro — is covered on the Tennessee growing guide.
Timing shifts within Tennessee
Tennessee isn't one climate. In Johnson County, the last hard freeze (28°F) holds until about Apr 14 — roughly 21 days later than the recorded state median — so plant cilantro to your county's window, not the statewide date.
Cilantro needs about 35 days of frost-free season to complete its cycle. Even Johnson County — Tennessee’s shortest season at 193 frost-free days — clears that by 158 days, so season length isn’t the constraint anywhere in Tennessee. What varies is your own parcel.
Across Tennessee’s 95 counties the frost-free season runs from 193 days in Johnson County to 266 days in Shelby County — a spread of 73 days, which is why a single statewide planting date misleads. The median Tennessee county sees 230 frost-free days, leaving cilantro about 195 days of slack on a typical parcel — room for a second sowing where the season runs long.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Cilantro's 35-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Cilantro draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, cilantro can only work that bloom inside Tennessee's frost window — roughly 230 days, opening after the last 28°F freeze (Mar 21 - Mar 29) and closing at the first (Nov 5 - Nov 12), per NOAA Regional Climate Centers ACIS, 1991-2020.
Recommended Cilantro Varieties for Tennessee
Tennessee publishes no state variety trial for cilantro, so we won't invent a "best for Tennessee" list. Choose types rated to your USDA hardiness zone (6a-8a), and confirm winter survival and drainage against your own parcel.
Tennessee Cooperative Extension
For Tennessee-specific cultivar recommendations, planting calendars, and pest pressure for cilantro, the canonical source is UT Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Cilantro native to Tennessee?
No — the USDA PLANTS Database lists Cilantro as introduced rather than native in the Lower 48, so it is not part of Tennessee's native flora. It grows here as a garden plant; pairing it with a few Tennessee natives keeps local pollinators fed too.

Common Questions About Growing Cilantro in Tennessee
When can I plant Cilantro in Tennessee?
Tennessee's last spring hard freeze (28°F) clears between Mar 21 and Mar 29, and the first fall hard freeze lands between Nov 5 and Nov 12 (NOAA Regional Climate Centers ACIS, 1991-2020). Cilantro is frost-tender — its killing temperature is 32°F (FAO ECOCROP — the point where cold damages growing tissue, not a winter-survival floor) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
Can Cilantro mature before first frost in Tennessee?
Yes — Cilantro matures in 50 days (Growable Ground Plant Database), and Tennessee's dependable hard-freeze-free window runs 221 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 171 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Cilantro grown in across Tennessee?
Tennessee spans USDA hardiness zones 6a-8a (USDA ARS PHZM 2023). Cilantro carries a range of zones 2-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Tennessee site have?
A typical Tennessee site sees ~230 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Cilantro needs 35+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Johnson, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Cilantro native to Tennessee?
No — the USDA PLANTS Database lists Cilantro as introduced rather than native in the Lower 48, so it is not part of Tennessee's native flora. It grows here as a garden plant; pairing it with a few Tennessee natives keeps local pollinators fed too.
How should I amend the soil for Cilantro in Tennessee?
Cilantro tolerates pH 4-8 and well (dry spells) drainage (FAO ECOCROP). That is a 4-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Tennessee site — amend for drainage and organic matter first.
Will Cilantro actually grow on my specific land in Tennessee?
