One who clips grapevines or cuts down reeds — R’ Yose HaGlili says: He must move [the cut] one handbreadth away. R’ Akiva says: He may cut in the normal way with an axe, a sickle, a saw or with whatever he should want. A tree which has cracked may be tied during the seventh [year], not so that it will heal, but so that it will not deteriorate further.
