Having someone else do the grafting

Hi,

Just as one may not graft a branch from one species of tree on to a tree of another species, so one may not have a non-Jew do this on his behalf. This follows the view that both Jews and non-Jews are instructed against cross-species grafting.

(Code of Jewish Law Yoreh Deah 295:2; Beiur haGRA Yoreh Deah 295:4)

Have a great day,
Mordechai
