Where to put the Sukkah Where to put the Sukkah 1. It is forbidden to build a Sukkah under a tree. The roof of the Sukkah must be made of plant materials but these must be detached.
Many people have their trees trimmed especially for the holiday.
This has a double advantage. The area is made kosher for a Sukkah and the branches and leaves can be used for the roof. The above statement is true despite the fact that the Sukkah is in motion with respect to the ground in the case of the wagon, and the ocean in the case of the ship, the highway or the air in the last two cases. Because in all the cases, the Sukkah is at rest with respect to the wagon or the ship or the truck or the wing. Rather, it is quite still.
