Tu Bishvat: the greening of Judaism Available in on-screen reading friendly (PDF) and printer-friendly, downloadable (PDF) versions. For more booklets, visit our Booklets for People in Interfaith Relationships page. This beautiful booklet tells the historical roots of Tu Bishvat and Judaism’s long-standing sacred connection to trees. You will also find suggestions for activities for young children and ideas for hosting a Tu Bishvat seder. It is a great handout for preschool and elementary school children to take home and can be the basis for a class or used by a taskforce that wants to add a Tu Bishvat seder to the synagogue or school calendar. Please add it to your regular schedule of holiday booklets at your school, synagogue or agency.
