As for the Korean hornbeam it's not a finished tree, it's a work in progress. I got it from another grower a few years ago and did a bunch of large chops on it. Got it into proper bonsai soil, akadama, pumice, lava, a bit of charcoal (Boons mix basically.). It still needs ramification development. The other grower had it in potting soil for over 20 years so that's a lot of age for such a little tree, now it needs ramification work to become a great tree, then a proper bonsai pot. I'd say it's 5-10 years from being show ready.
