What is a likely consequence of having decurrent trees that are not regularly pruned?

Having decurrent trees that are not regularly pruned can lead to the development of codominant stems. Decurrent trees, characterized by their broad, spreading crowns, tend to grow multiple stems or leaders rather than a single dominant one. When these trees are not pruned, competition among the stems can arise, resulting in two or more leaders that have similar size and strength. This can create a structural weakness in the tree as the branches vie for dominance and space, which may lead to increased risk of limb failure, especially in high winds or storms.

Regular pruning helps to maintain a strong central leader and reduce the likelihood of codominant stems developing, promoting better structural integrity and health of the tree. Without intervention, these trees can become unstable and more susceptible to damage and disease, negatively impacting their longevity and aesthetic value.
