Trees are the key to the liveable city of the future. They make a significant contribution to the natural balance in the built environment. Climate change, extreme heat and drought alternated with excessive rainfall make ever greater demands on the urban environment.

The Ebben TreeEbb is a wide-ranging tree tool which enables you to put together the perfect range for every green project in just a few clicks. In TreeEbb you will find an enormous collection of distinctive planting varieties with descriptions of varieties and photographs.

Trees and ecology

Through evaporation, trees create increased humidity and help to reduce temperature and CO₂. In towns and cities, along motorways and in industrial areas, trees also ensure better air quality. Trees help in the absorption of harmful pollutants, such as VOCs, ozone, nitrogen dioxide and particulate matter.

In cooperation with landscape architects, district planners, green contractors, arborists and other green professionals, we put together an inspiring programme of courses, including workshops and lectures, for the green sector.

The tree-planting season for trees in open ground starts from the moment that their leaves fall in the autumn. The planting season ends when the new buds start to emerge in the early spring.

A planting hole should be dug carefully. The space which the tree gets in the planting hole is not the same as the space taken up by the root system. In addition, soil improvement is often necessary before trees are planted in urban areas. This can be done by turning over the soil, preparing the planting location with tree sand or tree gravel, or improving it with fungal dominated humus compost.

Trees require care, particularly during the first years after planting. The first pruning is important to optimise the root-to-crown ratio. During dry periods, the tree will not yet be able to find enough water itself, so watering is also indispensable during the first three years. And just like in natural situations, the tree needs nutrients to grow.

Once the tree has been planted, it must be anchored, to ensure it does not start to bend over or rock as well as to prevent new root growth being damaged by the tree moving too much. 

An accurate description in the specifications will ensure that you are supplied with the right trees and plants. Check here which parts are important for the specifications. 

The right equipment is very important for transporting trees to the project site. The contractor who will be planting the tree must be aware of the dimensions and weight of the trees beforehand and must take these into account in their quotes.

For landscape architects, trees form important elements to create structure and atmosphere, in combination with other planting and the structures within the design.

Trees and lamp posts are often placed alternately in a straight line. This often leads to problems. Three factors are important for determining the distance from a lamp post to a tree: 1. the branch-free stem up to where the crown begins; 2. the crown width; 3. the height of the light point.

The Urban Greenery 2021 project was started in 2009 by the Bavarian State Institute for Viticulture and Horticulture. It is a trial to test trees in order to achieve the widest possible range that can withstand the urban climate and heat and drought stress.

Guided pruning, maintenance pruning, pruning shape trees and pruning topiary trees? You will find everything that you should know here.

Shape trees are trees that have and maintain their shape without intensive human intervention. Topiary trees get their shape through pruning.
