Which method is used for dealing with co-dominant stems in trees?

Co-dominant stems occur when two or more stems emerge from the same point on a tree trunk, leading to potential structural weaknesses. The appropriate method for addressing co-dominant stems is through co-dominant stem removal. This technique helps to reduce the risks associated with structural failure, as co-dominant stems can grow together at their tips, creating a weak union that may not adequately support the weight of the canopy.

Removing one of the co-dominant stems alleviates competition for resources and helps improve overall tree health and stability. By taking this proactive step, arborists can also help promote better canopy structure, allowing remaining branches to grow without the constraints imposed by competing stems. This method is particularly important in maintaining tree aesthetics and safety, especially in urban or utility environments where trees may pose a hazard if they become unstable.

Other options might suggest selective removal of only the larger or smaller stem, or believing that no removal is necessary, but these approaches do not effectively address the inherent structural problems posed by co-dominant stems.
