Can I Grow Cloudberry in Tennessee?

USDA Zones 6a-8a · Plant zone range 2-5

Not Verified — Winters This Mild

Not verified for winters this mild: cloudberry is listed for zones 2-5 — a growing recommendation, not a heat limit — and we hold no heat rating for it. Tennessee runs zones 6a-8a, milder than that range, so this page gives no verdict here. The frost window and season figures below are measured for Tennessee.

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 cloudberry 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 Cloudberry Stands in Tennessee

Cloudberry is rated for zones 2–5 — a cold floor USDA puts at -50 to -40°F. No Tennessee county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about Tennessee winters, not about cloudberry.

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.

When to Plant Cloudberry 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

Tennessee runs as cold as USDA zone 6, and no sourced winter-hardiness floor is on record for cloudberry, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether cloudberry is a permanent planting or a replant-every-spring crop for you turns on your own zone within Tennessee; check its hardiness range against that before treating it as long-lived ground.

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.

Soil + Drainage Fit

Cloudberry tolerates a wide pH range (pH 4.5-7.8) — 3.3 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 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. pH range, preferred pH and drainage need: We haven't confirmed this against a published source yet.

Before you plant cloudberry 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 cloudberry 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.

Federal record: High

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.

Know Before You Grow

  • •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
  • •TRI facilities report what they release. Check the wind — downwind beds catch more of it.
  • •Mine waste leaches heavy metals. Test for lead, arsenic and cadmium before growing food here.

What Else to Consider for Cloudberry 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 cloudberry — is covered on the Tennessee growing guide.

Where in Tennessee Cloudberry's Listed Zones Fall

Cloudberry is rated for USDA zones 2–5. Every Tennessee county sits above it. Even Carter County, the state’s coldest at zone 7a, is milder than the plant’s zone 5 ceiling — the constraint here is winter chill it will not get, not cold it cannot take.

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. None of that range reaches the band cloudberry needs, so here the statewide answer really is the answer.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Cloudberry’s zone 2–5 band: Not verified. A parcel report resolves your address’s own zone and frost dates rather than its county’s.

Pollinator + Wildlife Value

Cloudberry draws native bees (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, cloudberry 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.

Tennessee Cooperative Extension

For Tennessee-specific cultivar recommendations, planting calendars, and pest pressure for cloudberry, the canonical source is UT Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Cloudberry native to Tennessee?

Cloudberry is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Tennessee. It can still earn a place in a Tennessee garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Cloudberry in Tennessee

When can I plant Cloudberry 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). No sourced winter-hardiness floor is on record for Cloudberry, so this page does not state whether it overwinters in Tennessee and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.

What hardiness zone is Cloudberry grown in across Tennessee?

Tennessee spans USDA hardiness zones 6a-8a (USDA ARS PHZM 2023). Cloudberry is listed for zones 2-5, which do not overlap them, so there is no zone in Tennessee where this page can call outdoor growing reliable. A parcel report resolves your own address's zone.

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). Cloudberry needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.

Is Cloudberry native to Tennessee?

Cloudberry is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Tennessee. It can still earn a place in a Tennessee garden — the zone comparison above tells you whether it will thrive.

How should I amend the soil for Cloudberry in Tennessee?

Cloudberry tolerates pH 4.5-7.8 and well (dry spells) drainage. We haven't confirmed this against a published source yet. That is a 3.3-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.
