Anyway.. in 2018...I decided to sh!t or get off the potty. I was never going to be happy with the tree. I decided to strip one side of the trunk and lay the tree down to see to if I could create something out of not much. Today, I decided to have look and conduct an Autumn repot. I wish I had a photo of the original tree but it seems not or I just cannot find it.
Anyway here are two pots (in August 2018) after the tree was laid down and some cutting taken too. Look carefully at the first photo - in the middle, a root cutting with no foliage - that makes a re-appreance with roots and leaves later. And the same pots as they were this morning too. And the photos below are what transpired earlier today. I am happy. No so much with the current layout - rather that I have learned to take something rooted (pardon the pun) and create a root-connected setting that I can now work with, enjoy and potentially make something interesting over time.
Much better than before. Of course, other thoughts welcome and the lesson is ... before you chuck out a tree or dismiss it altogether, make sure there aren't other options. Not much to lose and a lot to learn.
Below is the root cutting from the first photo in this thread.I nearly seperated this cutting to make a single tree... but in the end, I removed that fat root and added back to this setting.
PS - The rocks in the current photo are not part of any design - just holding parts of the tree in place.

PPS - And somewhat buoyed by the success of the root cutting ... why not bang in eight more with the left over root from this tree.
This won't be a group planting ... just an experiment, banged-in a pot before a storm hits Melbourne in about five minutes time!! If they take, I'll seperate them later and figure out what to do. What's to lose?
