That can inform how giant of a minimize it is advisable make on the rootstock. You need them to match up like puzzle items.
For a veneer graft, use your knife to create an angled minimize into the rootstock that extends a few quarter of the way in which via. The depth isn’t the essential half, although.
The essential factor is that the scion and the rootstock angles match up and the cambium layers meet when pressed collectively.
