How to Grow Cloudberry

Rubus chamaemorus · Zones 2-5

Cloudberry is a perennial grown for its fruit. It's hardy across USDA zones 2 through 5. Its late spring flowers are a moderate draw for native bees, even though the fruit is the prize. It roots deep, which helps it reach moisture in a dry spell and open up tight soil as it establishes.

What Cloudberry is

Cloudberry grows as a perennial and reaches around 6 inches at maturity. It blooms white in late spring.

How to grow Cloudberry

Cloudberry grows in USDA zones 2 through 5. Cloudberry does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.5 to 7.8, on well-drained ground. It needs a growing season of at least 120 frost-free days, which is why climate matters as much as soil.

  1. Start the season right

    Plant cloudberry in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.

  2. Match the soil

    Cloudberry prefers pH 4.5 to 7.8 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.

  3. Water steadily

    Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.

  4. Harvest at maturity

    Pick when the fruit is full-colored and parts easily from the stem. Local Cooperative Extension guides publish timing tables.

Where Cloudberry thrives

Cloudberry is hardy across USDA zones 2 through 5. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 25 spans average winter lows from -50°F to -10°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 3 outright and splits 30 more down the middle — and which side of that line your land sits on changes the answer.

Where Cloudberry stands, state by state

Cloudberry is rated for zones 25 — a cold floor USDA puts at -50 to -40°F. Across the 50 states and DC, 3 sit fully inside that band, the line runs through 30 more, and 18 sit outside it — and inside every split state, the same line runs on at county grain.

Too little winter chill rather than too much cold — a low-chill selection is what changes it. Each link is that state’s own growing hub.

Good to know

Cloudberry offers moderate value to bees and other pollinators.

Before you harvest cloudberry, know your soil

Anything you grow to eat takes up what's in the ground it grows in, so it's worth knowing what's documented near you before you plant cloudberry for food. Our free screen reads 9 federal source types across roughly 1.8M indexed sites and shows which sit near your address and which way they drain. It's a screening estimate from public records and proximity — not a soil test — so a nearby record means a soil test is worth it, not that your soil is unsafe.

How we know this about Cloudberry

The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions

Can I grow Cloudberry in my zone?

Cloudberry grows in USDA hardiness zones 2 through 5 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.

When should you plant Cloudberry?

Most growers plant cloudberry after the last spring frost, once the soil has warmed, leaving enough of the season for its 120-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.

How much sun does Cloudberry need?

Cloudberry needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.

What soil does Cloudberry need?

Cloudberry prefers soil pH 4.5 to 7.8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.

Does Cloudberry attract pollinators?

Yes — cloudberry's flowers are a solid nectar source for native bees.

Is Cloudberry safe for pets?

Cloudberry is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
