As this picture from the end of July 2001 shows, the tree grows very well. At this time, I have cut away many of the larger leaves in the top. That explains why the crown looks so flat. In reality it is much more rounded but that silhouette will have to wait until the leaves have reduced further in size and I am pleased with the ramification.
The bulb on the right size is ugly. It comes from a large pruning scar from the initial shaping six years ago. I have a strong feeling this flaw will only worsen with time. Does anyone have a proposal how to fix this?
