That’s what I noticed , thise field grown pines especially, seems like the pots are either undersized and they need more room to develop more right? That’s why I wonder if some of those trees don’t get repotted into a grow pot , and the nice pots they’re in are used for something else or set aside till the tree is ready for them again.
It's interesting to read some of the descriptions. A few of the trees had history beyond Ryan's ownership. That silverberry was one of those, although Ryan said its actual history is unknown. It's an old Japanese import and is pretty darn nice. The hyperbole about its being possibly the best one in N.America is a bit over the top, but it's probably close. There is one at the National Bonsai and Penjing Museum donated by John Naka's son that isn't all that much better than the one in Ryan's sale.
One of the more annoying things about most of the trees in the sale (including that silverberry) is that they're potted WAAAAY too high in their pots...it's a common theme.

My observation/takeaway from many of Ryan’s lectures is that he really leans heavily on the container to constrict roots and reduce foliage size. He talks a lot about it in the context of ponderosas, but it has been mentioned in other contexts too.
Personally, I don’t mind a bit of a mound. I understand this is sacrilege for the ultra-traditional. I do try to minimize in my own practice.
