Since 1993, the Landscape Below Ground Conference has provided a forum for presentation of the latest research and management practices in all aspects of tree root development in urban soils. The conference’s impact on arboricultural practices has been significant; practices now commonplace, such as load-bearing soils that provide space for root growth beneath pavement, were introduced to international audiences at the conferences and through conference proceedings.

Carrying on this tradition, the 4th Landscape Below Ground Conference, presented by The Morton Arboretum and the International Society of Arboriculture, will be held October 15-17, 2018, in Lisle, Illinois. Like the three preceding conferences, this event will foster closer cooperation between disciplines and geographic areas, inform managers and policy makers about current research efforts, and foster practical improvements to tree planting and care.

The program will include the latest research on:

  • Tree root development and management
  • Managing urban soil environments
  • Tree root system biomechanics
  • Root structure and stability
  • Tree production, planting and establishment
  • Infrastructure conflicts and solutions
  • Construction damage and preservation
  • Planting site design 


Notes: The conference is held entirely indoors. Pre-conference workshops may be held indoors and outdoors.
