Tilia_6 update

Update of the lindentree, that I collected on a small mountain.

- The development within three years
- Nobody liked the tree on the internet, I mean the linden had been offered on a selling plattform.         Obviously vending was not successful ...
- Anyway, now the tree stays with me
- The nebari on the lefthand side has to be improven ofcourse.
- I will try to reach this by root-grafting or/and the "bycicle-rubber"-technique ...
- I will describe that special technique in a posting this summer
