Graft a tree: different techniques
The transplant of a tree, definition
The transplant consists of to reproduce a tree, or to rejuvenate it. To do this, a graft, which is a part of a plant, bud for example, is implanted on another plant called rootstock. This technique is particularly used for fruit and roses especially.
The transplant of a tree takes place in several ways: English, inlay, slit, crown or escutcheon, the last three being the most widespread because they are simpler to implement.
Whatever transplant method used, different tools are needed: secateur, saw, serpette, putty for graft, adapted tape or raffia.
Split graft of a tree
Split graft occurs in a branch or cut trunk, 2 to 7 centimeters in diameter, split in the middle up to 5 centimeters deep.
The graft, composed of 3 eyelets, is bevelled then inserted in the slot with a screwdriver, on the edge and in the continuity of the rootstock, and making sure that the bud closest to that it is oriented outwards.
Once the graft is done, flexible scotch surrounds the notch all the way up, and putty is applied to the wound.
The operation can also be performed with two grafts, each placed on the opposite side. Also, this graft can be in half-slot or in terminal slot, depending on the varieties.
The crown transplant of a tree
For the crown graft, the rootstock is prepared by slicing its bark, about 4 centimeters, in several places of its turn but at 5 centimeters of each other.
The grafts, 15 centimeters maximum in height, have a diameter of the size of a pencil and are composed of 3 buds. These are bevelled on one side, about 4 centimeters, then implanted in the different slots of the rootstock, taking care to slide them under the bark slightly peeled beforehand.
As for the split graft, large scotch and then putty are applied.
The crest of a tree
The escutcheon differs from previous techniques since it is carried out on a young plant of 2 to 3 centimeters in diameter, in which a T-shaped incision is made.
The graft, called in this case the shield, is a sample of bark on which pushed a leaf with a bud at the petiole; the leaf is cut but the petiole and the carnation are preserved.
This patch is then placed in the incision of the rootstock, under its previously open bark. Both must fit perfectly and the part of the escutcheon protruding from the incision should be cut off if necessary.
Large scotch or raffia then covers the round of the graft, leaving however the carnation.
The success of the escutcheon is appreciated if the carnation turns yellow or if a new shoot is formed, depending on the season in which it is carried out.
