In the depths of winter, when much of the natural world lies dormant, the Jewish calendar marks an unusual holiday, Tu BiShvat, the New Year of the Trees. This ancient observance, which falls on the 15th day of the Hebrew month of Shevat (typically in January or February), has evolved from an agricultural technicality into a celebration rich with environmental, spiritual, and cultural significance.
Origins and Meaning
Tu BiShvat’s origins are distinctly practical. In ancient Israel, the date marked the beginning of the agricultural new year for calculating the age of trees, which was essential for determining when their fruit could be eaten and how they should be tithed. According to biblical law, fruit from trees less than three years old was forbidden, fourth-year fruit was dedicated to God, and only from the fifth year onward could farmers freely consume and sell their harvest.
The rabbis of the Talmud debated the appropriate date for this arboreal new year, with the School of Hillel prevailing with their choice of the 15th of Shevat. They selected this date because, in the Land of Israel, it typically marks the end of the rainy season and the beginning of the trees’ period of renewal, when sap begins rising and the earliest-blooming trees, particularly the almond, start to flower.
The name itself is straightforward: “Tu” is a combination of the Hebrew letters tet and vav, which together have the numerical value of 15, while “Shevat” is the month. Thus, Tu BiShvat simply means “the 15th of Shevat.”
Evolution Through History
For centuries after the destruction of the Second Temple in 70 AD and the subsequent Jewish exile from Israel, Tu BiShvat remained a minor date on the calendar, primarily noted for the fact that certain prayers and fasts were omitted. Without an agricultural society in the Land of Israel, the holiday lost much of its original function.
The observance gained new life in the 16th century when Kabbalists, Jewish mystics, in Safed, in northern Israel, created a Tu BiShvat Seder. Modelled loosely on the Passover Seder, this ritual meal involved eating specific fruits and nuts in a particular order while drinking four cups of wine that gradually changed from white to red. Each element carried symbolic meaning, representing different spiritual worlds and the relationship between humanity and the divine creation.
This mystical tradition spread through Jewish communities but remained obscure until the modern Zionist movement embraced Tu BiShvat in the late 19th and early 20th centuries. For Jews returning to Israel and working to make the desert bloom, a holiday celebrating trees took on powerful nationalistic significance. The tradition of planting trees on Tu BiShvat became widespread, symbolising the physical and spiritual renewal of the Jewish people in their ancestral homeland.
Modern Celebrations
Today, Tu BiShvat is celebrated in diverse ways across the Jewish world, reflecting both traditional practices and contemporary concerns.
Eating Traditional Foods: The most universal custom involves eating fruits and nuts, particularly those associated with the Land of Israel. The Torah praises seven species for which the land is known: wheat, barley, grapes, figs, pomegranates, olives, and dates. On Tu BiShvat, Jews make a special effort to eat these fruits, often trying some fruit they have not tasted in the past year to recite the Shehecheyanu blessing, thanking God for allowing them to reach this season.
Dried fruits and nuts are especially popular, as fresh produce is limited in winter. Many families enjoy carob, sometimes called “Jewish chocolate,” which was historically eaten by the poor and has become a Tu BiShvat tradition. In Israel, where the almond trees bloom around this time, fresh almonds are particularly prized.
Tu BiShvat Seders: The mystical seder created by the Kabbalists has experienced a revival, particularly in more spiritually oriented communities. These seders involve readings, songs, and the consumption of fruits, nuts, and wines in a prescribed order. Modern versions often incorporate contemporary environmental readings and reflections on humanity’s relationship with nature.
Tree Planting: In Israel, Tu BiShvat has become an unofficial national Arbor Day. Schoolchildren across the country participate in tree-planting ceremonies, continuing the Zionist tradition of afforestation. Outside Israel, many Jewish communities support tree-planting in Israel through organisations like the Jewish National Fund, or plant trees locally.
Environmental Activism: Since the 1970s, Tu BiShvat has increasingly been celebrated as a Jewish Earth Day, with the holiday serving as a platform for environmental education and activism. Synagogues and Jewish organisations use the day to discuss ecological issues, promote sustainability, and explore traditional Jewish texts about environmental stewardship.
Cultural and Spiritual Legacy
Tu BiShvat’s enduring significance lies in its ability to carry multiple meanings simultaneously. It connects Jews to their agricultural heritage and the Land of Israel, regardless of where they live. For religious Jews, it offers an opportunity to fulfil commandments related to fruit and blessings. For secular and cultural Jews, it provides a nature-centred holiday that can be celebrated without extensive religious observance.
The holiday embodies a distinctly Jewish approach to the natural world, one that sees creation as both a divine gift and a human responsibility. The requirement to wait three years before eating from a newly planted tree teaches patience and long-term thinking. The tradition of planting trees emphasises legacy and investment in the future. The mystical interpretation of different fruits and trees as representing spiritual realms suggests that the physical and spiritual worlds are deeply interconnected.
In recent decades, as environmental concerns have moved to the forefront of global consciousness, Tu BiShvat has provided Jewish communities with a traditional framework for engaging with ecological issues. The holiday demonstrates that environmentalism is not a modern innovation but is rooted in ancient wisdom about living sustainably on the earth.
Tu BiShvat reminds us that even in winter’s depths, renewal is beginning beneath the surface. Trees that appear dormant are preparing for spring’s abundance. Similarly, the holiday suggests that even in difficult times, we can plant seeds, literal and metaphorical, for a better future. In celebrating the New Year of the Trees, Jews affirm their connection to the natural world, their heritage, and their responsibility to nurture both for generations to come.
