After the summerholiday in 2016 in France, i brought a souvenir with me to Holland. As you can see, this tree has much natural deadwood and has a very big nebari: about 20 cm! Before working, at the first picture at the trunk is about 60 cm in height. But there's some special with the tree: when the tree was in his original habitat, thickened part which in now the nebari, was a part of the trunk itself. The original roots are at the left side. There is also a white stone completely stucked in the roots; it's part of the tree. You can see a small part of it at the left site.
At the beginning of the growing season of 2017 the Buxus started growing a little bit. He had made it! I hardly couldn't wait to start training the tree, but it was too early. So i made a virt of the tree.

This could possible be his future looks. I couldn't photoshop all the deadwood at the nebari to a nicer shape, so nothing changed about that.
Because of the long thick root to the left, i put it on a slab. I think its the most natural solution of the problem, at this moment. Maybe there will grow more roots near the nebari, so i cut the long 'root'. The size of the tree should become almost 30 cm.

At the end of this season the tree was healty enough to select some small branches. I put some wire around them and bend them in the right direction. I think that this is a good step to develop a nice bonsai. But this will cost at least about 6 years. Maybe more... What exactly to do with the deadwood, i don't know yet. But time will tell.

To be continued...

Thank you for this post. Nice to see some interesting material on this forum. Impressive base!
I look forward to its development.

Very nice material, congrats
I wouldn´t alter the deadwood in any way just preserve it with some wood hardener.
And I would carve the top "jin" somehow to go with it.
Good luck and I am looking forward to development of this beauty too

Love the long term planning

thank you all!
i see that the virtual isn't visable (anymore?). so:

Here an update of this tree, this year the tree started well.. so he is fully recovered now..

Looks like this could become a really nice tree!
