I mean answers to horticultural bonsai questions and/or problems.
I didn’t really intend to hijack IntriguedByBonsai’s thread, but nonetheless I did. What set me off was Attila Soos’ rant that “…by and large, WE HAVE NO IDEA what to do with these wonderful trees [pinus contorta = lodgepole pine]. We don't even have a Mugo book, for goodness' sake. Neither [do] we have a Redwood, or a California Juniper book, which is beyond comprehension.” You can read all about it there; I won’t repeat it here.
What I had in mind was native American species and/or species we commonly find in home gardens. Japan has its native species bonsai and Europe has theirs. I know that I will offend some, but in America we basically have junipers. Otherwise, we seem to keep working with Japanese species (not that there is anything wrong with that). The only real change lately is Ryan Neil loves Ponderosas and Randy Knight finds the best yamadori. I know that other people have been doing serious stuff, but this is how the American bonsai scene impresses me in the short time I’ve been playing on its outskirts. But this is just background. I don’t mean to restrict BNuts in any way.
So, for me there are two basic issues to begin with:
My thinking is that we collectively can find our own answers using cheap/junk trees. These might be nursery trees (even saplings) or ‘junk-adori’. The point is that each of us should accept the fact that we are probably going to kill a lot of trees in the process. Killing trees, of course, is not the goal. Learning something, answering our horticultural questions is the goal. But it will cost money in dead trees - hence the sole reason for experimenting with cheap junk.
Regarding 1. Repotting: Vance Wood has demonstrated that Mugo pines are best repotted in August/September. My bet is that most, if not all, conifers likely can be repotted this same time of year as well as a large number of deciduous trees. I know from home-gardening experience that woody perennials (like roses) can similarly be repotted at that time of year. Further my wife made me aware that, ‘everything just stops growing then – its like the plants all take a deep breath before starting their fall work of getting ready for winter’ (or words to that effect). I’ve been intrigued by the question of why does Vance’s revelation work, thinking that maybe it has a connection to the shift from early wood to late wood. I’ve yet to find anything in scholarly papers so far, but I keep encountering studies that talk about ‘growth cessation’ in August/September with pines/spruces growing around the Mediterranean (Israel, Spain), to as far north as Finland.
I am suggesting that we repot (meaning bare root and root prune) some conifers and deciduous (angiosperms) trees when they have ceased growing for the season (August/September). What species are of common interest?
Regarding 2. How to treat it: Is far more complex question (set), IMHO. Ryan Neil, has extensive university horticultural study in addition to his extended apprenticeship with Kimura. He starts with separating out single flush species from those like JBP that can produce multiple flushes in one season. This could be a suitable first group experiment if we don’t know or want to challenge conventional wisdom. I am boggled right now.
What do we want to work on: lodge pole pines (pinus contorta), junipers, and redwoods per Attila Soos? Hemlocks (Tsugas) and Douglas firs? Arborvitae (american/western/eastern ‘cedars’)? What are our common interests?
From here, I suppose it will make sense to form a group or groups for our collective projects rather than leaving bits and pieces laying all over the place for the coming season(s).

So, for me there are two basic issues to begin with:
- When can we repot (meaning with root pruning and hence dig yamadori) trees?
- Spring, ‘as buds swell’ is known
- August/September when growth stops??
- If I can’t treat it like a JBP, then how?
