Ideas and Beliefs
The Bible expresses a great reverence for fruit trees as symbols of G-ds bounty. Special laws were formulated to protect fruit trees in times of war and ensure that the produce of trees would not be picked until the trees were mature enough and tithes were given from them. In order to calculate the age of trees, both for determining when they could be harvested and when they were to be tithed for the Temple, the Talmudic rabbis established the 15th day (Tu) of the month of Shvat as the official birthday of trees.
Subsequent to the destruction of the Temple, Tu Bshvat lost much of its relevance, but in the middle ages it was rediscovered by Jewish mystics. In the modern period it has enjoyed another revival as a holiday that links Jews with the land of Israel and as a Jewish celebration of the environment.
Practices
When the Temple stood in Jerusalem, Tu Bshvat served as the day on which farmers offered the first fruits of the trees they planted, after the trees had turned four years old. The following Tu Bshvat signified when the farmers were allowed to begin making use of the produce of the trees they planted, whether for personal or economic reasons.
In the middle ages, the Jewish mystics of Safed developed a ritual meal celebrated on Tu Bshvat that was modeled on the Passover Seder. Four cups of wine were drunk and seven fruits, symbolic of those of the Holy Land, were eaten. With the rise of Zionism in the late 19th century, Tu Bshvat was rediscovered as a celebration that links the Jews with their land. The holiday became one of rededication to the ecology of the denuded land, with the planting of trees taking center stage in the celebration. Jews outside of Israel contribute money to plant trees there and/or plant trees in their own communities.
With the increased concern for the environment in recent years, Tu Bshvat has taken on an additional meaning, as a day on which Jews can express and act on their concern for the ecological well-being of the world in which we live. This has led to the rediscovery of the mystical Tu Bshvat Seder, now transformed into a celebration of G-ds bounty and the environment.
