Hard winter earth. Gray February days. Thank God for hidden sap!
Celebrating trees when we are surrounded by cherry blossoms — or other local tree-life — might seem more sensible than doing so on a day like today. But Judaism’s “tree holiday,” is more about the tiny bit of sap, running unseen under winter earth, than it is about visible signs of new growth. Tu B’shvat, the 15th of the month of Shevat in the Jewish calendar (Feb. 8 this year) is the “New Year for Trees.” According to Talmudic discussion, it takes place after “the greater part of the year’s rain has fallen and the greater part of the cycle is still to come” (Rosh HaShanah 14a).
Two notes in Siddur Koren Mesorat HaRav, although both offered as commentary on the morning blessings, seem particularly pertinent for this holiday.
