The aim of this thesis was to examine planting at parking lots of shopping centers and to check the adequacy of the design and maintenance of the plants. Six locations were chosen in Ljubljana for the case study: The Spar supermarket in Štepanjsko naselje, the Tuš supermarket near Ruski Car, the Mercator market in Nove Fužine, the Aleja mall and Mercator hypermarket in Šiška and the Interspar Vič center. We have identified the species composition and type of plantings of the parking lots (line/solitary/clump planting of trees, shrubs and perennial plants), and after reviewing adequate literature, assessed the suitability of each species in terms of adaptability and functionality for the selected planting areas. Due to the predominance and purpose of trees, the thesis focuses on tree planting. Shrubs and perennials appear only in more recent plantings. We compared the growing space of trees, represented by grass areas or individual pits with a modular iron grate, with the DIN standard (DIN 18916). We checked for the presence of damage, which in most cases was caused by the lack of water or inadequate plant protection. By designing and maintaining the plants appropriately, their functionality is maintained. In newer plantings, where the trees are still in the early stages of their growth, their functionality is not fully effective, as they cannot provide shade to vehicles parked below, for example. These trees mainly have aesthetic and structural functions, with the ecological function being intensified as they develop.
