What might cause a tree to be structurally weak?

A tree's structural strength is influenced significantly by its root system and overall health. Root damage can occur due to various factors, such as physical injury, soil compaction, or excavation near the tree. When roots are compromised, they cannot effectively anchor the tree, leading to instability and a greater likelihood of failure.

Moreover, decay and diseases can weaken a tree's structure internally. Fungal infections, for example, can hollow out the trunk or roots, reducing the tree's ability to support its weight and resist external forces like wind. This deterioration affects the integrity of the tree's structure, making it more prone to breakage or falling.

In contrast, consistent watering and proper sunlight promote healthy growth, while compost as a fertilizer provides essential nutrients that enhance overall vigor. Healthy growth conditions support a strong structure, hence not contributing to weakness.
