    Based on the processing of literary sources and our own research, we studied the features of grafting ornamental forms of Morus alba: ′Pendula′, ′Globosa′, ′Pyramidalis′, ′Contorta′, ′Macro- phylla′ and ′Tatarica′. It is proposed to distribute these ornamental forms according to the grafting and budding dates: winter – the second or the third decade of February – the first decade of March; spring: early spring (the second or the third decade of March); spring the average (the first – the second decade of April); late spring (the third decade of April – the first to the second decade of May); summer – the end of the first decade of July is the first decade of August. It is in- vestigated that the best period for its holding is the first and the second decade of April. It is deter- mined that the most effective method of winter grafting is improved copulation, which was carried out in early March – the highest average splicing of various components after grafting of these plants was observed in forms ′Tatarica′ (70 %) and ′Macrophylla′ (60 %). When grafting plants by splitting in these forms, the highest average splicing is also noted – compared 61 % and 54 %. The highest splicing results of grafted plants during their spring grafting were also obtained by applying the improved copulation method in forms ˊTataricaˊ – (88–92 %), ˊPendulaˊ – (78–84 %) and ˊMacrophyllaˊ – compared 65–75 %. The largest number of splices of grafted plants during grafting by applying the method for behind the barkis noted in form ˊTataricaˊ (87–91 %, a little lower – in ˊPendulaˊ (73–77 %) and ˊMacrophyllaˊ – compared 64–72 %. It was investigated that the wild plant (M. alba) and its studied ornamental forms resemble their internal structure and the grafting sites are quickly spliced and are completely covered with a protective fabric before the onset of the rest period.
