Deep Roots Research (webcast)

Webcast by Gary Johnson from the University of Minnesota regarding the problems associated with deep or buried root systems.

Deep or buried root systems have been causing problems for arborists for decades. When root systems stop functioning normally, the entire tree system begins a progressive decline in health and stability.  For almost fifteen years, the University of Minnesota has been studying the effects of three types of dysfunctional root systems:  buried roots, stem girdling roots (SGRs), and pot-bound root systems.  This webcast focuses on the SGR frequency surveys, predisposition to wind storm failures, and the effectiveness of root pruning techniques.  This is a webinar resource.  Length: 64 minutes.
