Last year I acquired this JBP. I was confident I could improve the density of foliage and put it into a larger recovery pot (red wine box) since then the needles have opened up a lot more and I have started to see new adventitious buds forming. Cool.
The problem with the tree, apart from removing the dead moss from the trunk, is the dead lower branches. Some of the upper branches have already been pulled down to cover these. You can see the history here http://www.artisticbonsaicircle.co.uk/e001ch1.htm
Assuming the branches are completely dead grafting will not be possible, I am going to borrow a thermal imaging camera to see if this is the case.
Opening up the discussion - I think the options are
- cut the dead branches off
- try and hide the dead with live density - I prefer 'fuller' trees
- train a couple of branches down from higher up and try and fake it
- leave the dead branches alone, not sure about this otherwise I wouldn't have proposed as a problem.
I am of course open to ideas...
