Kilaim 5:8-6:1

Kilayim 5:8

If thorns grow in a vineyard and the owner allows them to remain, Rabbi Eliezer says that they are prohibited but the Sages permit them. According to the position of the Sages, only things that are typically allowed to remain are rendered prohibited. Iris, ivy, white lily and seeds are not kilayim if they grow in a vineyard. Rabbi Tarfon says that hemp is not kilayim in a vineyard but the Sages say that it is. Artichokes are kilayim in a vineyard.

Kilayim 6:1

What constitutes an aris (vines trained on a trellis)? If one plants a row of five vines next to a fence that is ten handbreadths tall (about 30”), he must leave four cubits of space (about six feet). Beis Shammai say that this is measured from the vines towards the field, while Beis Hillel say that it is measured from the fence towards the field. Rabbi Yochanan ben Nuri says that everybody is wrong! If there are four cubits from the roots of the vines to the fence, then a space of six handbreadths is left (about 18”) and the rest of the field may be planted. Rabbi Akiva says only three handbreadths must be left.
