Conditions for the growth of street plants have a number of features that are due to environmental, technological, chemical, physical, anthropological factors. The growth of outdoor plants takes place in the difficult conditions of urban agglomerations. The urban environment is characterized by elevated air and soil temperatures, air smoke, soil compaction and deterioration of its physical and chemical properties, and a limited amount of plant nutrition. These factors necessitate the implementation of a special approach to the care of outdoor tree plantations. Its effectiveness is viewed through the prism of plant resistance to unfavorable conditions of the urban environment and optimization of the factors of their vital activity. They provide for an assessment of the state of plantings, taking into account their species characteristics and biological characteristics. It is also planned to improve the technology of planting and caring for woody plants in the difficult conditions of urban agglomerations.
