Sheviis 2:5-6

Sheviis 2:5

One may oil and pierce unripe figs to speed up their growth until Rosh Hashana of the sabbatical year. One may not do this to unripe figs of the sixth year’s crop that go into the seventh (sabbatical) year, nor to those of the seventh year that go into the eighth. Rabbi Yehuda says that one may not oil them in a place where doing so is the practice because then it counts as work, but one may do so in a place where such is not the practice. Rabbi Shimon permits it because it is permitted to work a tree in the eighth year even if it bears produce of the seventh.

Sheviis 2:6

One may not plant a tree, sink vines or graft a branch in the sixth year of the sabbatical cycle within thirty days of Rosh Hashana. Rabbi Yehuda permits these things up to three days before Rosh Hashana because if a graft doesn’t take hold within three days, it never will. Rabbi Yosi and Rabbi Shimon say that one may do these things until two weeks before Rosh Hashana.
