Tree maintenance

In playgrounds, parks, on the street and in cemeteries - trees are vital for us. They produce oxygen, provide shade, cool city centers and collect particulate matter. They also provide habitats for insects, birds, bats and squirrels, for example. The tree maintenance team at Aachen's municipal utility company looks after, maintains and plants more than 130,000 city trees.

Tree planting

Every year, hundreds of new trees are planted in the city of Aachen. The prior planning is extensive: the location is checked, pipeline plans are obtained and in some cases archaeology has to be involved. Subsequently, civil engineering measures are implemented before the soil can be replaced. As the conditions are different everywhere, the experts from the municipal company select a suitable tree species for each individual location. If the tree is then finally planted, many steps must be implemented professionally so that the tree grows well. This also includes watering the young trees regularly in the first few years.

Tree inspection

Our city trees are inspected by the tree inspection staff at regular intervals of nine months to ensure that they are safe for traffic. Diseases, fungi and other damage are recorded and, if necessary, measures are determined. The data is processed and documented in a digital tree register. Each recorded tree has a profile in which the tree species, height, age and vitality are recorded, among other things.
Additional checks are always carried out after special weather events, for example after storms or heavy snowfall. Daycare centers, schools, playgrounds and parks in particular are then inspected.

Tree care

Gentle maintenance measures are carried out on trees throughout the year. For example, dead wood is removed to ensure the safety of the trees. In order to preserve severely damaged trees for longer, the tree maintenance staff use special measures. Among other things, the crowns of old trees, including natural monuments, can be preserved and stabilized with crown protection. Felling is always the last resort, but is often unavoidable in the case of diseased or dead trees.
