How to Grow Cloudberry
Rubus chamaemorus
Cloudberries are low-growing Arctic plants suited to cool, acidic, waterlogged soils. They are dioecious — you need both male and female plants to get fruit. Plant in a permanently moist, peaty bed in a cool climate and be patient; fruiting takes 2-3 years. Harvest the golden-amber berries before they soften. Not suited to warm or dry gardens.
Yearly Lifecycle
Care Essentials
Apply a light balanced fertiliser in early spring. Cloudberries are native to nutrient-poor bogs and tolerate low fertility well — avoid heavy feeding.
Watch For
- Botrytis (grey mould)
- Aphids
- Vine weevil
Pet Safety
Care Requirements
Light
Full sun to partial shade
Prefers full sun in cool climates. In warmer or drier sites, some afternoon shade helps retain moisture and prevents scorching.
Watering
Consistently moist; boggy conditions preferred
Cloudberries thrive in waterlogged, boggy ground. Keep soil permanently moist. Never allow to dry out. In cultivation, water generously and mulch heavily.
Fertilizing
Light balanced feed in early spring only
Native to nutrient-poor bogs. A light application of a balanced fertiliser in early spring is sufficient. Over-feeding promotes leafy growth at the expense of fruit.
Pruning
Minimal — remove dead stems in late winter
Remove dead or damaged stems in late winter. Trim spreading rhizomes in spring to prevent the plant from outgrowing its bed.
Spacing
60 cm apart in rows 90 cm apart
Space plants 60 cm apart to allow rhizome spread. Rows 90 cm apart for access. Allow a colony to form — larger groups fruit better.
Support
No support needed
Low-growing ground-cover habit; no staking or support required.
