What is the purpose of having a minimum distance between hardware in a non-adjustable support system for trees?

To ensure easier maintenance
To prevent the trees from growing properly
To avoid compression of tree tissues
To allow flexibility in tree movement

The correct answer is: To avoid compression of tree tissues

The purpose of having a minimum distance between hardware in a non-adjustable support system for trees is to avoid compression of tree tissues. When hardware such as cables or braces is too tight or positioned too closely to the tree, it can place undue pressure on the tree's bark and cambium layers. This compression can disrupt the tree's vascular systems, impede growth, and potentially lead to long-term damage or decay of the tree tissues. Proper spacing allows for natural movement and growth while ensuring that the support system remains effective without harming the tree. While maintenance is a consideration, the primary concern with spacing is related to the health and vitality of the tree itself, not making maintenance tasks easier. Similarly, creating distance does not serve the purpose of preventing proper growth; rather, it facilitates it by ensuring that the tree is not restricted. Flexibility in tree movement is generally a characteristic of adjustable systems or dynamic cabling, not static supports where minimizing tissue pressure is paramount.
