Whip Graft in Place
The cion and stock shown previously are here placed together in such a way that the cambium layers of the bark of the cion and stock come in contact. Only this inner layer of the bark is composed of active living cells, and the graft will be a failure if the living tissues of stock and cion are not in contact. It will be seen that only one edge of the cut surface of the cion is in contact with the cambium layer of the stock. But this serves every purpose.
