- Q. Should, one also plant a tree outside of Israel on Tu Bishvat? Is that also a Mitzva?
A. In general we rule the mitzvos that depend on the land or “Mitzvos Hatluyos Baaretz”, apply only to the land of Israel unless they were explicitly included by the Torah in different ways. (Kidushin 36a, etc.), however, we may maintain that it is also a mitzva on the people to plant trees.
The first opinion seems to be the rule. It is not common to see Gedolei Yisroel devoting time and effort to the planing of trees outside Eretz Yisroel.
However, in some particular instances, as required by the private needs of individuals and their families, it could be a mitzva.
