I’m not familiar with Bjorn’s technique, so I can’t comment other than to say, if it works, it works.What about the technique suggested by Bjorn, he defoliates most of the outer canopy leaving only the inner leaves. And I've read from you and from other sources to cut ONLY those first, inner leaves, leaving the rest intact. Sounds like two opposing approaches? Or am I missing something here?
Btw, completely agree on flower priority, mine now has several straight and leggy branches which I'll terminate after the show in winter!
The technique I described comes from my teacher, Boon, and is also presented in an early International Bonsai magazine article.
