The City of Stockholm invites to a seminar on how to use structural soils as a sustainable solution for local management of storm water and extending the life of urban trees.

Discoveries made in recent years concerning root growth and the design of suitable tree substrates to develop a robust, load-baering root space are used by the City of Stockholm to develop a concept for the improvement of urban trees. An important element in this concept is the systematic utilization of rainwater from surfaced areas for watering of trees in a well ventilated medium with high coarse-pore content.
