Among the Gifts of Galadriel, given to the Fellowship while they were in Lothlorien, was:
a small grey wooden box with a silver rune "G for Galadriel". In the box was earth from Galadriel's orchard. The box also contained a silver nut from a Mallorn tree, the last east of the sea, and west of the mountains. This was given to Sam.
Sam put this gift to good use, helping to heal and repair the damage Sharkey had done to the Shire. Did Elrond, Galadriel and Gandalf also try to use their rings or other powers to help heal some of the hurts and damage done by Sauron after the One Ring was destroyed?
Edit addition: Considering their effect in healing the Shire, Galadriel's gift of the Mallorn tree nut and soil from her garden would be a good example of 'other powers' being used to help repair some of the damage wrought by Sauron's influence. Are there other examples, either subtle or gross of any of the three ring holders helping to repair Middle Earth before they leave for the West?
