Vertical Green is a more and more used option to green up highly sealed urban districts. While the foliage density of climbing plants is comparatively high in contrast to the low space requirement, vertical green can help to cool down open spaces by using adiabatic cooling and reduces urban heat islands. An essential factor to achieve these effects is the health of the plants leaves. Strong leaf damages can reduce the annual growth, foliage density and even lead to dropping the leaves early in the year. Beside a reduced aesthetic, weakened plants do not provide their full potential of microclimatic effects. This work examines the known leaf diseases and damages of selected climbing plants. It is also its goal to summarize the state of the knowledge of the topic. Based on the results of the literature research monitoring sheets were developed and the abnormalities on the foliage of 15 container-based climbing plants in Vienna recorded. Referring to the previous results an interview guide was drawn up and six experts were interviewed. During the literature research, it became clear that there is no analog or digital published work about the diseases and damages of climbing plants in particular. Also standard literature concerning the greening of buildings predominantly does not include common diseases and pests. The results of the monitoring showed that neuroses (26%), withers (20%), twists (17%) and chloroses (15%) are the most common leaf diseases at container-based Lonicera ssp., Parthenocissus ssp. and Wisteria ssp. in Vienna. During the interviews it became clear that besides a forwardlooking planning also the construction and continous care are crucial for the success of a container-based greening. The results of this work can be seen as a first collection of the known leaf damages and diseases at selected climbing plants. It connects the effects of planning, building and cultivation to the health and vitality of container-based climbing plants.
