Before one would begin to answer a multitude of questions here, on
both sides of the conversation,
is there more than one tree here in this post? Your post says there are, I'm not so sure.
You also mention one of them is in another thread, I don't understand the quiz because I think
I'm only seeing one of your mugos in this post, sorry.
Please link other thread now that the quiz is over. I'm just now seeing these posts from October
Judging by the soil in the last full sized pic, the akadama is breaking down. Appears to be a smear perhaps as a clue.
How is water passing through? When did you get it? I assume recently since you asked how deep the roots are
When did you prune it etc...
I only ask because the ROR is so intriguing and uncommon in this thread.
Only thinning and cleaning up should have occurred this year, prior to repotting, not pruning as much.
I do wish there were growth left on at the point just above where the trunk crosses the rock
and the curve threw off a branch.
It should with proper care still become a nice mugo. I like it...a lot!
