This paper addresses the issue of poor condition of trees in urban areas. The health condition of tree stand depends on many factors. Conditions prevailing in the city often do not provide for proper growth and development and allow only the vegetation of trees lasting several years after planting. Manifestations of tree health problems are usually visible lesions within the crown or trunk and are only effects of adverse factors on the root system. The most dangerous causes of ill health in trees are associated with intensity of the negative anthropopressure impact in the cities, affecting the changes in the soil environment. A thorough read of the processes occurring in the urban soils allowed presentation of the methods used to ensure adequate habitat conditions for trees in Europe and North America. Awareness of the need to use systems has increased in recent years in Poland. Attempts to use a variety of methods used worldwide and technologies used in the Polish cities allow to analyse the systems in terms of their effectiveness as well as potential barriers and opportunities for their implementation. The aim of the research is to designate the systems with long-term beneficial effects on the trees, the use of which would have impact on life extension of the trees in Polish cities.
