Choosing where to graft a pecan tree.
The first tree I came to was a little over six feet in height with a top divided into three main branches (photo at right). For some, this tree would provide the prefect opportunity to place a 3-flap on each of the branches in an effort to increase the likelihood of obtaining at least one good graft. However, grafting close to the top of a tree actually increases the probability the tree will reject the grafts and simply grow around the scions.
bark graft to attach the scion to stock (photo at right). As my usual custom, I then attached a bamboo stake to the tree to protect the scion from bird damage and provide a place to tie up the scion's new shoots to prevent wind damage.
Because I removed so much of the top of the stock tree, this scion will grow with a lot of vigor. I'll trim the scion down to a single shoot about 4-6 weeks after grafting. The combination of vigorous growth and a single shoot will make training this new tree to a central leader shape very easy.
