Preparing on this trident Maple the cambium for a better healing and to do a double graft next year over the cambium. With this it will heal very fast. We removed all the deadwood from last years cutting wound and go until we come to a living part all around, cover it with cutpaste and the wound can heal for a few centimeters and this is what we need to put next years graft in.
Last year I prepared one branch and put it in position with wire were we miss an important branch. I wanted to do the grafting with a branch as thick as the others. That is why I need the wood of the branch of 3 years old. On the photo you can see the place and the branch that we are going to graft.
We need to carve in the trunk exactly on the place were the branch has to come. The depth of the carving has to be the same as the thickness of the branch. It has to fit in perfectly over the whole length. Than we remove the bark on the inside of the branch that there is a good contact between branch and trunk. Never use cutpaste on grafting wounds.
We are using a grafting robe to close everything very thight to each other. Bend it 3 double to be sure that there is no air in between.
Grafting is finished, you can see on this photo very clear that the position of the branch we used has been prepared the year before. How long it will stay on? That is always the question. The part that is coming out will grow thicker than the part that is going in and than it is ready to be removed. We always count about two years. The biggest mistake you can make is to remove the robe too early.
