Final answer:
Girdling a tree involves cutting a band of bark, disrupting nutrient flow, leading to the tree's death. Professional arborists should handle the killing and removal of trees.
Explanation:
Girdling is a method of cutting a band of bark around the tree, which removes the phloem and cambium layers while leaving the xylem intact. This process disrupts the tree's ability to transport nutrients and eventually leads to the tree's starvation and death.
As the phloem and cambium layers are crucial for nutrient transport and growth, removing them through girdling prevents the tree from receiving essential nutrients, causing it to wither and die over time.
Professional arborists should handle tree killing and removal to avoid accidents and safely eliminate dead or unwanted trees.
