Tu B’Shvat is the New Year for trees.
In Israel, Jews plant trees on Tu B’Shvat.
Traditions include: eating nuts and fruits, donating funds to plant trees in Israel, focusing on environmental issues, and holding a Tu B'Shvat seder.
Tu B'Shvat literally means the 15th of the Hebrew month of Shvat.
Tu B'Shvat began as a tax day of sorts, when Jews determined which fruits would be included in the tithe brought to the Temple.
Tu B'Shvat has taken on the character of a Jewish Earth Day or Arbor Day.
