Name a common sign that a tree may need support.

A leaning trunk or branches is a common sign that a tree may need support because it indicates that the tree is experiencing structural instability. This could result from factors such as soil erosion, root damage, disease, or insufficient anchorage. When a tree leans, it may not be able to withstand strong winds, leading to the risk of falling or breaking. Providing appropriate support, such as cabling or bracing, can help stabilize the tree and prevent potential hazards.

In contrast, bright foliage, healthy growth, and the presence of blossoms typically signify that a tree is in good health and not in immediate need of support. These characteristics reflect vitality and adequate growing conditions rather than structural issues. Therefore, noticing a lean is critical for tree care and maintaining safety in the surrounding environment.
