Thank you for watching!
With regard to measuring... I suppose in this case, where the trunk begins to expand, and slightly above the soil line, is where I measured. This, with the thought in mind that eventually more of the nebari will be exposed (not for now, to encourage root growth).
I will adjust with that in mind on future measurements though - thank you for the walk--through on that - I would say a bit above where I measured then.
Re: pruning - basically, I'd like to have pushed more down the trunk on the trident. I will post the root/trunk/repot video by end of the weekend... there were so limited number of fine roots (crappy nursery pot that had poor soil) and this was my FIRST major surgery on any tree... so I got spooked to be honest to take any more.
With regard to timing of pruning, I was instructed that least traumatic time is before the buds push. So anything further, I'd want to wait for this tree to get healthy before putting it through more... let me know if you think otherwise... not really any further buds other than that primary foliage.
Plan would be grow in new pot for 2 years, evaluate strength of roots, and attempt more severe chop. Thoughts?
