3-flap graft. This past weekend, I found the buds on the scion greening up and the rootstock already trying to out grow the new graft. In the photo at left, note that the buds on the scion have expanded to about one-inch-green. Below the graft are two red-tinged shoots that have already grown over 12 inches in the past 3 weeks. Reddish growth is a characteristic of juvenile tissue and is common among pecan seedlings.
I'll be back to this tree in a couple of weeks to tie the scion's new growth to the bird perch to prevent wind damage.
