The statement is true. When staking a tree, the material used for attachment plays a crucial role in the tree's growth and stability. Broad, smooth, and flexible materials help prevent damage to the tree's bark and cambium layers, which are essential for nutrient and water transport. These materials minimize the risk of girdling, where the binding material constricts the tree, potentially leading to slow growth and even death.

Using a broad and smooth material ensures that the weight and tension are distributed evenly, reducing the chances of injury. Flexibility allows the tree to sway naturally in the wind, which helps it develop strong trunk supports and roots over time, adapting well to its environment. If the attachment material is too rigid or narrow, it could create pressure points that may harm the tree as it grows, leading to long-term health issues. Therefore, the correct attachment material not only supports the tree initially but also facilitates healthy development as the tree matures.
