What do longitudinal bulges of response growth indicate?

Longitudinal bulges of response growth indicate a potential issue within the tree, specifically suggesting possible internal cracking. This phenomenon occurs when a tree experiences stress or trauma, leading to the formation of abnormal growth patterns. As the tree tries to heal and re-establish its structure, it may produce bulges along its trunk or branches. These bulges are a visual sign that the internal wood may have been compromised, potentially resulting in internal cracks.

While healthy growth signifies a well-adapted and stable tree, and external pest damage or inadequate watering can manifest in different symptoms, longitudinal bulges are specifically associated with internal issues that need to be assessed further to prevent potential failure or decline of the tree. Understanding these indicators helps in monitoring tree health and implementing appropriate management strategies.
