The pomegranate tree in The Kite Runner signifies youth and innocence. When the boys are young they visit the tree often. They eventually carve their names in the tree which signifies their innocent pledge of devotion to one another. The reader later learns that the pledge is broken.
The tree also symbolizes the end of their friendship. The author writes later that the tree no longer bears fruit. This signifies a type of death. This same death can be seen in the boys' friendship.
The author creates two unique messages through the pomegranate tree. The first is the innocence of the boys’ friendship. As the innocence fades, so does the boys’ friendship as well as the life of the tree.
