The first experience of transplanting large-sized coniferous dendrointroducents (Picea glauca (Moench) Voss, Larix sibirica Ledeb.) in the spring-summer period without preliminary prepara-tion of the root system in the urban conditions of the Polar region was presented. Four specimens of middle-aged plants of both species were selected. The transplant was carried out with the max-imum use of mechanized equipment, which ensures good preservation of the lump and the tree it-self. There were four mutually related stages of work (preparatory, digging out plants, transporta-tion, planting), the quality of which depends on the success of plant survival. A brief description of the decorative qualities, morphometric parameters and the state of the experimental plants has been given. It has shown that due to the peculiarities of the soil and the location of the root system in coniferous introduced species, a clod of earth should be at least 60 cm thick, with a diameter of 110 to 130 cm. The main agrotechnical methods for the creation and care of plantings from large-sized plants were given.
