The article presents the results of the study of vegetative reproductive potential (VRP) of ornamental woody plants assortment group Juniperus in the South-West of the Central Russian upland. The research was conducted in the 2017 season at the production site of the Botanical garden nursery of the Belgorod State National Research University. Cuttings were made by standard methods. Semi-woody cuttings were cut in late may-early June. Then, some of them, acting as a control, were planted immediately in a closed ground, and part – treated with root formation stimulants, and then planted in a closed ground. As a result, it was found that dusting with «Kornevin» Is the most effective way to stimulate root formation in semiwoody cuttings of plants from the selected assortment group Juniperus, evenly and significantly increasing their VRP at the initial stage of vegetative reproduction. Following on the effectiveness of the effect on the rooting of cuttings, there are grounds to consider stimulants «Ribav extra» and «Zircon», used in the form of solutions in which the cuttings are soaked for 12 hours.
