Graft placement influences scion vigor
3-flap graft was placed on a side limb of a young sapling. If you look at the top of this tree, the stump visible between the two upper-most shoots was probably the location of a second 3-flap graft that ended up not taking. In any case, the new shoot from the successful graft is only about 8 inches long--way too little growth for a new scion during first year after grafting. The upper portion of this tree should have been pruned off as soon as the shoot on the successful graft was 2-3 inches long (at that point you are certain the graft has succeeded) . All those leaves and shoot growth above the graft only served to slow the growth of the scion.
bark graft to place the scion on the stock. Once the buds on the scion had grown out about 3 inches, I selected the strongest new shoot to become my new central leader and pruned off all the competing scion buds. This photo was taken in mid-July and I had over 3 feet of new growth that could be easily trained to a bamboo stake.
