You can clearly see the graft splicing into the existing trunk and branches. It looks to be a good bond. The bond will be tested in the years ahead as the branch gains weight and volume.
This is year three for these Kalamata grafts. It has been two and a half years since they were grafted, so this year is the first fruit. While its only a small quantity on this graft it is a promising start.
Interestingly another graft tree has grown faster than this one it is three meters tall. It has no fruit this year. Our theory as to why? It has been happily putting energy into growing tree rather than fruit. Quite why it chose to do this is another theory again!
