If one plants [a tree] as a hedge or for [its] beams, [it] is exempt from orlah. R' Yose says: Even if he said: “The inner side [of the tree] is for food, and the outer side is for a hedge,” the inner side is liable and the outer side is exempt.

At the time that our forefathers came to the Land, [any tree that] they found planted [was] exempt. One that they planted, even though they had not yet conquered, is liable.  One who plants for the public, [it is] liable. R' Yehudah exempts.  One who plants in the public domain, or a non-Jew who planted, or a thief who planted, or one who plants in a boat, or [a tree] that grows on its own —- is liable to orlah.
