Now this looks awful, I admit. I put fire to every singly piece of deadwood on this tree.
If you look close you can see that a lot of the foliage on the frontal left side is burned. That is due to a silly accident. An 'empty' gas can accidentally got in touch with a still very hot torch and startet to burn. What an irresponsible way to burn a tree and almost cause an explosion! Well, I am guilty and I will not do it again. As I can tell nothing very serious happened. The branches are burned, but only slightly and will live.
A full solution of lime sulphur was painted all over the deadwood. It looks gray as the wood is black from fire.
