Tu B’Shevat, or “new year of the trees,” began as an agricultural festival in Israel, marking the start of spring. Today the focus has turned to ecological awareness. There are many ways to celebrate Jewish Arbor Day: You can get out in nature, take a hike, plant a tree or build a garden. Or if you don’t want to get your hands dirty, you can simply enjoy a meal or a concert. Tu B’Shevat falls on Monday, Jan. 21, with many Bay Area events taking place in the days before and after the holiday.
