I like all the opinions on here! And also i enjoy chatting will fellow enthusiasts on what they see and how they would do it themselves!
I did the work today and i had alot of fun doing it. whether it was right for tree, its health and its design and so on only the future will tell. But lockdown is making me pursue some excitement.
SO i ended up removing the stone. It wasn't easy nor difficult, but something in between. It didn't slip out but it wasn't clinging to rock either. most so a little stuck in the surrounding roots, but with a little patience i managed to get it out with out damaging too many roots (i hope/think)
First i took it out of its pots and it was definitely ready for a repot.
and here it is with out the stone.
from the side
from the future front
so i was obviously left with roots that wasn't really able to move much. i should have expected that they wasn't magically gonna be able to move around free and positioned in a nice and natural way. but oh well i well figure it out next year. I put the tree back in the pot with new soil and with the exposed roots part i wired them i liiittle bit closer together, wrapping the neagari part in grafting tape and filling it with soil. and a bit of moss. I'm gonna exchange the tape for some netting (the stuff i have has too big holes for this mame soil.
So here's the tree now back in its pot
Now i'm gonna try and hope it's comes back to good health. Then in time i wanna downsize the pot work in jining the rest of the branches and create a shari. But i'm gonna go slow from this point.
here's another bad drawing of what i want to achieve
amount of soil and root i removed
I actually tried halving the rock. that didn't work.
I don't know if anyone finds this vaguely interesting. but i'm interested in your thoughts if you have any
