Cions Showing One, Two, and Three Buds
A cion with a single bud, like that in the center of the picture, will serve the purpose, and may be employed where wood is precious, as in case of a single seedling of a choice variety. Ordinarily, however, a cion is cut to include two or three buds, thus making allowance for the possible failure of one or more buds. Small twigs like these, if grafted near the ends of branches of an old tree will bear fruit in perhaps half the time that would be required if they were left on their own roots.
