The best size is one-third of an inch in diameter, that of stock and cion being the same since the two must match exactly.
Any one, with a little practice, can learn to cut a cion, and to graft with success.
The piece of root serves as a temporary support, and roots are emitted along the cion.
If the cion greatly outgrows the stock a weak tree is the result.
It is well to split all stubs on such branches horizontally, that one cion may not stand directly under another.
The little tongue of bark on the stock covers the base of the cion, when it is set.
So he grafts them when they still are young,—takes a cion from the kind which he wishes to perpetuate.
The cion is tied tightly to the stock (B, Fig. 75), usually with raffia.
The requirement is to cause the cion and stock to grow together solidly, making one piece of wood.
Many grafters apply a bit of wax to the tops of the cion also.
