Why do we eat a new fruit on Rosh Hashanah?

On Tu B'Shavat we eat new fruits?

Could it be that there is confusion regarding when or why we eat new fruits. The Gemara masechta on Rosh Hashana tells us that there are four new years. However we need to learn the specifics of why we eat new fruits on Rosh Hashana, and then again on Tu B'Shavat?


only thing said there is that it is the new year for trees, and there is a dispute as to the proper date for the holiday (Beit Shammai said the proper day was the first of Shevat; Beit Hillel said the proper day was the 15th of Shevat. As usual, we follow Beit Hillel. For more on Hillel and ShammaiThere are few customs or observances related to this holiday. One custom is to eat a new fruit on this day. Some people plant trees on this day. A lot of Jewish children go around collecting money for trees for Israel at this time of year. That's about all there is to it.
