The process of grafting trees.
The scion or seedling/sapling tree to be grafted needs to be prepared and shaped in the months prior to grafting. This is necessary so that it will fit into position at the base of the main trunk.
If both scions grow, one is removed after the first year. Generally the union is not tied, the pressure of the under-stock stub being strong enough to hold the scion in close contact.
Dwarfing: To induce dwarfing or cold tolerance or other characteristics to the scion. Most apple trees in modern orchards are grafted dwarf or semi-dwarf trees planted at high density.
Scion - A woody stem or small section of a tree or shrub used to propagate a new plant by grafting on a rootstock. The scion holds the characteristics of the new plant; - the root stock enables it to grow quickly.
The species of tree to be grafted it is called the 'scion' and the tree to which it will be attached is called the "root-stock.
Grafted plants for bonsai often present problems in the training stages, or later as the plants get older due to differing rates of growth between the root stock and scion and because of differing bark characteristics.
The reason for producing a grafted tree is to impart the growth characteristics of the root stock onto the scion.
When its new life has started scions of garden varieties suitable for dwarfing are grafted on the upper portion. In a few years beautiful flowering potted trees are formed.
Each free graft involved inserting a scion of 3-5 leaves into a chiseled area in the recipient tree. Once the graft was secured with plastic tape, it was sealed into a plastic bag into which several drops of water were placed.
T-budding is done in spring when bark is slipping on rootstocks propagated the previous year from seed or cuttings. Simple wedge or V-grafts can be made in winter or spring. Scions 2-3" long, taken from the central portion of 1-yr shoots, ...
