The White Tree dies and is not replanted
Event Type: General

"After the disappearance of Earnur and the ending of the kings the White Tree seldom again bore fruit, and each year its blossom grew less as it slowly aged."
PoMe Peoples of Middle-earth, Part 1, Ch VII, The Heirs of Elendil
"When Belecthor II, the twenty-first Steward, died, the White Tree died also in Minas Tirith; but it was left standing 'until the King returns', for no seedling could be found."

The dead tree was left in the courtyard until after the Ring War when Elessar found a sapling and replanted the White Tree.
