the.com/wishing tree

means A tree (real or decorated) where people attach coins, ribbons, rags, or written notes as a physical token of a wish or prayer, often at a shrine, holy well, or pilgrimage site.

from The custom is ancient and widespread rather than tied to one source — in Britain and Ireland, 'clootie trees' near holy wells were hung with strips of cloth tied to the ailment or wish, left to rot away as the wish was believed to take effect; in parts of Asia, coins were pressed into tree bark or trunks for luck, and paper wishes still get tied to branches at temples. The English phrase 'wishing tree' is simply descriptive, a label applied to this much older, scattered folk practice rather than a word with a single traceable root.
