Tennessee is not one climate
Tennessee’s winter-low ladder runs across 95 counties, from zone 7 in Carter County to zone 8 in Tipton County. That is 10°F between the two counties’ average coldest night — the difference between bay laurel overwintering in the ground and coming under cover.
The middle half of 95 counties runs 7.5–7.5 zones, with a median of 7.5 zones — a 1-zone span end to end.

Where in Tennessee Fits Best
Bay Laurel is rated for zones 8–10 — a cold floor USDA puts at 10 to 20°F. Against Tennessee’s 95 counties that band holds in 6 of them, and the line runs at Fayette County (zone 8a), the coldest county still inside it.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.
Even within Tennessee's zones 6a-8a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for bay laurel (USDA PHZM 2023):

When to Plant Bay Laurel 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.
Winter standing
Bay Laurel overwinters from USDA zone 8 and warmer (NC State Extension Gardener Plant Toolbox), and Tennessee runs as cold as zone 6, so it does not survive winter in the ground here. It is a woody plant rather than a crop you resow each spring, so neither a fall establishment date nor a harvest countdown describes it in Tennessee — which is why this page gives neither. What it needs here is a way through winter, not a planting date.
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 bay laurel survives winter in part of Tennessee, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Growing degree days
Bay Laurel needs ~2000 GDD (base 50°F) to ripen. We haven't confirmed this against a published source yet. 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
Bay Laurel tolerates a wide pH range (pH 4.5-8.2) — 3.7 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 and 6.5 — 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, a raised bed lifts the roots above wet ground, or work in compost. Drainage need: We haven't confirmed this against a published source yet.

Before you plant bay laurel 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 bay laurel 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 — 22,517 documented sites across 7 of the 8 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 of imported, lab-tested soil grow well almost anywhere in the meantime.

What Else to Consider for Bay Laurel 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
What to actually do about these — and the constraints that apply to every Tennessee grower, not just bay laurel — is covered on the Tennessee growing guide.
Where in Tennessee Bay Laurel Is Zone-Hardy
Bay Laurel is rated for USDA zones 8–10. 6 of Tennessee’s 95 counties fall inside that band. The coldest that does is Fayette County at zone 8a. 89 counties sit below the plant’s zone 8 floor, where an unprotected plant is relying on snow cover and a mild year. Where you are in Tennessee decides this one.
Across those 95 counties Tennessee’s winter-low ladder runs from zone 7a in Carter County to zone 8a in Tipton County — 1 USDA zone of spread, which is 10°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Johnson County holds its last hard freeze (28°F) until about Apr 14, while Shelby County is clear by Mar 4 — 41 days apart. Set bay laurel out on your county’s date, not the state’s.

Pollinator + Wildlife Value
Bay Laurel draws honeybees (low value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, bay laurel 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. Pollinator value: We haven't confirmed this against a published source yet.

Common Questions About Growing Bay Laurel in Tennessee
When can I plant Bay Laurel 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). Bay Laurel overwinters only from USDA zone 8 and warmer, and Tennessee runs as cold as zone 6, so it does not survive winter in the ground here — the question for Tennessee growers is how to carry it through winter under cover, not which week to plant it.
What hardiness zone is Bay Laurel grown in across Tennessee?
Tennessee spans USDA hardiness zones 6a-8a (USDA ARS PHZM 2023). Bay Laurel carries a range of zones 8-10, 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). Bay Laurel needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for Bay Laurel in Tennessee?
Bay Laurel tolerates pH 4.5-8.2 and well (dry spells) drainage. We haven't confirmed this against a published source yet. That is a 3.7-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 Bay Laurel actually grow on my specific land in Tennessee?
