Referring to such a method of horticulture, it is imperative not to leave sawed 2-3 skeletal branches. They'll pull the juice, so the tree selected by the foundation of vaccinations will not lose power because of the short crop and will continue to live.
The procedure will be pleased with the result, if carried out in the period of active sap flow (before April 25). At this time the bark can be easily separated from the timber. It is useful in implementing pereprivivki branches that exceed the diameter of the thickness of the cuttings.
Performing the bark grafting can be reduced to uncomplicated algorithm of actions:
- Stripping sharp knife (garden, vaccination) on branch saw cut locations. This need for faster wound closure.
- Performing a longitudinal incision in the bark grafted branches. It is necessary in this case a knife blade to try to reach the layer of wood and do not too elongated incision, it will be sufficient length in the range of 4-6 cm.
- Separating and moving apart the bark of the stock for the free entry of scions. This action is useful for the butt of the knife. Rootstock called root system and a portion of the stem portion prior to connection to the graft.
- Performing an oblique cut to vaccinate the handle. cut length must exceed 4 times the diameter of the cutting.
- Sharpening the bottom of the cutting on the side opposite the slice, to facilitate its entry to the bark.
- Insert cuttings of the scion between bark and cambium of the stock. In this case, you need to follow to 1-2 mm slice could be seen over the SPIL.
