Abstract: Cloudberry (Rubus chamaemorus L.) cultivation is presently receiving more and more attention. A grower’s guide is available in Norway. However, site selection is imprecise with regards to soil physical and hydrological properties. Furthermore, compatibility of peatland restoration techniques with cloudberry cultivation has not been tested, as well as the establishment of Norwegian cultivars in Canada. Water table levels did not affect cloudberry growth, although physical properties were different between the two experimental conditions. However, more rhizomes were produced in fibric peat than in mesic peat. Mulching decreased the production of leaves. The Norwegian cultivar Fjordgull had the highest survival. These results suggest that cloudberry should be planted 2 or 3 years after peatland restoration, as well as in fibric peat that has received a limited amount of machinery work, thus having better porosity and physical properties.
