Nebari on the last piece Tom posted is absolutely crazy.
I've got some that are real nice there. That's a quality I seek and shows age and power.
Cork Bark Elm...
Dawn Redwood group.........
The Juniper is "done".
The Cork bark needs a trim and the new pot to fill in with moss/ground cover.
Lately I've been using Gloss and other aquatic species as ground cover experiments.
The Gloss you saw in my 120 Gal was living in a Ficus bonsai for 2 years, then I added it to my tank.
Dawn redwood needs to simply stay the same size and fatten up the trunk and branches. I may repot to a larger container some day.
The Olive might be a candidate for over a serpentine rock, I do not like the pot and the ground cover did not take well as I'd hoped.
So this will be changed this fall.
I have a larger Cork Bark oak I got 2 years ago as a pre bonsai and then a smaller one with nicer form which needs time mostly.
The Ficus are recovering from cold and winter, but have started to leaf out good.
The Manzanita is a pre bonsi still, it'll be 2-3 years before I call it a bonsai. They take more work and are wild collected. I will get some more pines this summer in the mountains and another species of Manzy also that come from sea level elevations.
