What is the purpose of bud caps?

The purpose of bud caps is primarily to allow trees to grow while protecting the leader from browsing. This protection is crucial during the early stages of a tree's development when the leader is more vulnerable to damage from herbivores. Browsing can stunt growth or inhibit the overall health of the tree, and bud caps serve as a physical barrier that protects these sensitive parts while still permitting the tree to continue its growth and development. By safeguarding the leader, bud caps ensure that trees can establish strong and healthy structures, which is essential for their long-term vitality and resilience.

In contrast, other options do not accurately capture the role of bud caps. Concealing a tree from pests is not their function, nor do they directly promote fruit production or prevent water from pooling. These roles are more aligned with other agricultural practices or protective measures but not specifically with the use of bud caps.
