It was root bound and because it seems that I may have lost a tree recently to this,I decided to chop it all off.
On close inspection, it seems the tree was potted at least twice as I had found fly wire mesh in within the soil

After removing all of the roots and some look like rot, I was left with not overly too much so I hope I can give it TLC for its recovery.
.. tips and critiques please

QS.. I need some branches lower on the tree.. what graft method is best ?
