Three trees belonging to three people combine and they may plow the entire beis seah on their account. How much [space] must there be between them? Rabban Gamliel says: Enough for [a team of] cattle to pass through with its implements.

[If] ten saplings are distributed within a beis seah, one may plow the entire beis seah on their account until Rosh Hashanah. [If] they formed a wall or were surrounded by a fence, one may not plow for them any more than their need.

Saplings and gourds combine within a beis seah. Rabban Shimon ben Gamliel says: Even [if there are] ten gourds to a beis seah, one may plow the entire beis seah until Rosh Hashanah.

Until when are they considered saplings? R’ Elazar ben Azaryah says: Until they become unsanctified. R’ Yehoshua says: A seven-year-old. R’ Akiva says: A sapling as its name. A tree that was razed and produced a shoot — from a handbreadth and down [it is treated] as a sapling; from a handbreadth and up [it is treated] as a tree; [these are] the words of R’ Shimon.
