Apparently well-known in Israel (a friend of mine said it didn’t work for her):
TU B’SHVAT SEGULA FOR SHIDDUCHIM
Take a piece of paper and write the single’s davening name on it with the mother and father’s davening name on it and hang it on an almond tree the day before Tu B’Shvat. Example: the single’s Hebrew (or Yiddish) name ben/bat the mother’s name and the father’s name on a slip of paper. It is important that the names be correct. Be sure to enclose it inside of a plastic baggy for protection from the winter weather and secure it on an Almond (Shkaydia) tree before the start of Tu B’Shvat. The names must be hanging on the tree from the beginning of Tu B’Shvat all through Tu B’Shvat. Motzi Tu B’Shvat remove the names from the tree and give them (or mail them) to the respective singles as soon as possible. Many times a parent, friend or neighbor is the one who initiates putting the slip of paper (petuch) on the tree for the unsuspecting single. The single must be willing to either sleep with the petuchim under their pillows or wear them pinned inside of their clothing or inside of a pocket for that year or until they marry.
Bad for Shidduchim

David,
Whether it works or not doesn’t matter, it’s definitely Darchei Emori at the least, but as long as they call it a segulah that will fix all their problems, the people will flock to easy “fixes” like these that give them false hope.
What if I laminate it instead of using a plastic bag?
My roommate heard about this last year and we both did it. And we’re still single 🙂
