Cultivation methods and production possibilities for roseroot (Rhodiola rosea L.), a decorative natural plant originated from Lapland have been studied in Mikkeli, South Finland, (61° 44 N, 27 ° 18 E) by Agrifood Research Finland during 1994-2002. Roseroot belongs to the group of medicinal plants called adaptogens, and products containing roseroot are popular on the US market and in Russia. In the first experiment the propagation biology, growth, biomass accumulation and characteristics of root yield were studied between 1994-1998. Between 1997- 2002, several field experiments were carried out to study different agrotechnical questions in organic conditions and the first version of cultivation technique was issued for growers. For large-scale production roseroot should be propagated by transplanting strong, two-year-old seedlings to the field covered by black plastic mulch, with a plant spacing of 40 x 40 cm. The root yield can be harvested mechanically in autumn after three to four growing seasons. The roots are cleaned, washed, sliced and dried at 40-45 °C. Fresh and dried root yields of 200-250 kg and 40-70 kg/100 m², respectively, can be expected.
