Dysfunctional Root Systems and Brief Landscape Lives: Stem Girdling Roots and the Browning of Our Landscape

Gary Johnson

Hidden below ground is an underground killer of many trees in landscapes everywhere: Stem Girdling Roots. Literally, these are roots that physically and physiologically girdle tree stems, causing premature death due to a decline in health or a sudden failure during a wind loading event. That is the bad part. The good part is that the problem is predictable, preventable and in many cases, treatable.
