Hi,

Yesterday we mentioned that one may not graft trees of different species.

Within a single species, one may graft different trees to improve one's fruit. Thus one may take a branch from one apple tree and graft it on to another apple tree.

However, note that wild crabapples and edible are considered different species. More on this in the next few days.

(Code of Jewish Law Yoreh Deah 295:6; Pitchei Teshuvah Yoreh Deah 295:2)

Have a great day,
Mordechai
