Further Training the Pecan Scion towards Dominance
While mowing around the pecan stump I'm resurrecting I noticed it was time to train the Scion once again. The fatal tree strike that killed the previous grafted portion on the stump took a year to kill the original tree. So does the repair by Topworking. Your work needs regular attention once a successful graft has been accomplished. Preventing the scion from being broken out by a bird, wind, critter, etc is necessary as well as keeping Nurse limb growth in check.

First I cut away the extra growth of the nurse limbs on the same shoot off the stump that I grafted on. While the scion's vigor was low I left 2 nurse limbs but the scion is taking off so I want to send more sap to the scion, it has healed & grown enough that now more energy is needed. My goal is to keep the scion growing at a faster pace but not so fast that the scion outgrows the strength of the joint. Slow is better than fast.

To help our scion with the competition I removed the nurse growth shielding the graft from direct sunlight. Since the leaves make the energy now the scion's leaves get the direct sunlight first.

I bought a bunch of pine 1x2's for scion support but recently had 2 grafts break due to the 1x2 breaking at a flaw in the wood. This scion I just supported with a heavy, galvanized, potted tree wire. It allowed me to shape the wire in a vise so it fit the scion perfectly. Duct tape was used to attach the wire to the tree trunk and tree ties was used (3) to attach the wire to the scion for lots of support.
More attention will be needed till the growing season ends so updates will follow.

A Good Example of a Full Graft Union

So the little scions will grow & grow till they completely take over the limb or trunk it is grafted on to. Here is 2 pictures of the same limb, one from each side. You can see the scion has completely grown to the limb. Till it's a union like this support is needed.

This limb is Headquarters. The only graft other than this is the source graft. Now Headquarters is a little larger than Elliot, same shape, same shelling issues. It's slow to bare too. I did this limb to just keep the source wood around. This Pecan tree is 5 varieties.
