When I go out into the field to graft pecan trees, I bring my tools, supplies, fresh scion wood, and the knowledge of several grafting techniques. The method I use to graft a tree depends on both the size of the tree and the diameter of my scion wood. It an earlier post I talked about grafting pecan trees when the tree is ready . One of the trees on my farm had grown over 2 feet last year, so it was time for this tree to be grafted.
The tree was about 1 inch in diameter so I decide to use the arrowhead graft. The key to a successful arrowhead graft is in carving the scion into the correct shape. First whittle the scion down into a thin strap (photo left). This strap should be thinner and narrower towards the bottom of the scion. You should also have a pronounced shoulder at the top of the cut surface.
The success of this grafting method is dependent on how well you can force the stock's bark to conform to the scion.
Last but not least, I attach a training stick/bird perch to the stock using plastic electrical tape (black tape). This training stick extends about 2 feet above the scion and creates a place for birds to land instead of on top of the scion. Many new grafts have been broken by perching birds when scions are not properly protected.
Once growth starts on the scion, tie the new growth to the training stick with grafting tape to prevent the wind from breaking out your scion.
