European oak #1 rescue of an old bonsai

European oak, Quercus robur, collected in Germany in 1992, first image of 1994. This tree has a long history. It was hollowed drastcally right in the beginning. Within ten years it became a presentable tree. In 2012 a very aggressive black fungus almost killed it. Subsequently lots of smaller branches and one large one died. Now it is rescued again. Most of the the ramification got lost but the structure is better now. The ramification will be there again in a few years. Pot by Derek Aspinall.
