A review of root barrier research

Morgenroth, J. (2008).Arboriculture & Urban Forestry, 34(2): 84-88.

The article describes various kinds of root barriers and their history over years- linear root barrier, circular root barrier and three-dimensional root barrier. Experiments have been carried out over decades to find suitable barriers for street trees. Studies show the importance and contribution made by these root barriers in allowing the roots to grow and expand in particular directions without hampering the curbs, sidewalks and other paved infrastructure. The most important finding to date has been the variability of root response to barriers seemingly influenced by soil type, environmental conditions, and species selection. The article also directs the future research scope in the field.
