Trees need to receive the right amount of light,shelter and rain,so you shouldn’t plant them too close to walls or buildings,because such positions can be shady and dry(roots of poplar and willow can also damage foundations and pipes).Tender trees often need a warm wall,however,if they are to flourish in a cooler region.Finally,make sure a tree can be seen from several angles especially when it is at its best.

Plants and the urban environment It is undisputed that the presence of plants e.g. in parks, roof or façade greenings or simple potted plants on balconies, contribute to the melioration of the urban environment. Some effects to be named are • Reduction of air temperature • Increase of air humidity • Reduction of air pollutants • Retention of rainwater • Reduction of noise • Increase of biodiversity and connection of habitats
