Tu B’shvat, the holiday traditionally celebrated here in Israel with planting trees and eating lots of fruit that was grown in the holy land, is actually not mentioned in the bible.

Prof. Jeffery Woolf, a professor in the Talmud department in Bar Ilan University, explains the evolution of this minor Jewish holiday to one that has been embraced in Israel as a symbol of rejuvenation. He spoke with reporter Arieh O’Sullivan.
