Plaque graft

 

I put like example a Graft of  Washington Navel  orange tree on lemon tree.

 

In the first place it is cut with the knife to graft the crust of the host in a smooth zone and without buds, doing two horizontal cuts united by a vertical section in form of laid down H. Soon with aid of the knife to graft the crust of the wood of each side is taken off as if we opened a window and a little stands out the crust of each side in vertical sense, so that soon it does not cover completely the plaque. Observe the clearest cambium under the crust, that it is the only part of the tree that grows and must make intimate contact with the cambium of the plaque.

 

Next of the knife to graft two complete horizontal cuts in the crust take control of a branch of the variety to graft, surrounding it completely, followed of another vertical section that one both horizontal cuts. Soon with the aid of the knife the crust is taken off and it removes finds out. This is the plaque to graft, that can have one, two and up to three buds.

The plate already taken off and prepared to be grafted.

In this case the plaque has two buds, indicated by both petioles of the leaves, that we will have cut to diminish the sweating of the graft. Notice the juicy inner cambium of clearer color. That is the alive part of the plaque and that must be united intimately with the cambium of the host.

Next the plate in the window of the host is placed, with the two parts of the crust already reduced, so that they do not cover the plaque completely. Observe that the plaque and the window of the host have the same measures.

Here the reduced crust of the host is appraised better, leaving discovered both buds with the petioles. The crust of the plaque, as much in its superior part as in its inferior part, must agree with the crust of the window of the host, so that there is a continuity, once taken hold the graft.

Next the graft is tied with transparent plastic tape, special for grafts of citruses. This tape is the same one that is used for the grafts in tomatoes and watermelons. It is very resistant, very easy to handle and its transparency allows to see the state of the graft. Once surrounded completely the graft, simply make two simple knots with both ends of the tape. Spent about 10 days, if the graft is successful, the petioles fall down touching them with the finger and leave a green affluent wound in the plaque. After 15-20 days untie the tape and, if they have not brought forth the buds already, they do not take too much in doing it.
