The pomegranate tree symbolizes Amir’s life in Kabul. When him and Hassan were younger they would play by the tree, however when he returns to Afghanistan he sees that the tree is dry and has no fruit growing anymore. Like the tree, Amir’s life in Kabul is just a memory now, and there’s nothing left but torn apart buildings and ruins. His friendship with Hassan and his past life has died and been life behind, just like the tree.
