How can over-pruning impact a tree's health?

• A. It can lead to increased fruit production
• B. It can promote quicker growth
• C. It can reduce vigor and increase disease susceptibility
• D. It has no effect on the tree's health

Answer: (C)

Over-pruning can significantly impact a tree's health because it disrupts the natural growth patterns and stress mechanisms that trees rely on to thrive. When too many branches are removed, the tree's ability to photosynthesize is compromised, leading to reduced vigor. This lack of vigor can make the tree more susceptible to diseases and pests, as it has fewer resources to allocate towards defense mechanisms. In addition, over-pruning can result in excessive new growth from remaining buds, which often leads to weak, poorly formed branches that are more prone to breaking and disease. Trees that are over-pruned may also struggle to recover, as they are left without sufficient foliage to support their physiological needs. This condition creates an environment where opportunistic pathogens can easily take hold, further endangering the health of the tree. Hence, the correct choice highlights the detrimental effect of over-pruning on a tree’s overall health and resilience.
