Forgive me for this long absence, since I retired, I have been working.
Deep Sea Diver,
It is I who am honoured by your comments and kindness to all.
I had written the rest of the article in English, this rest is the traditional presentation in tokonoma, I should find it in my computer.
My satsuki are doing great, this year I repotted more than a hundred trees.
I also worked a lot on my bonsai space.
It's far from being finished, but I'm making progress
I'm also working on my book, but it's difficult, there is so much to say about bonsai.
Shogun610,
Yes, of course, it can be several ferns together.
Sorry for my bad translation, I don't speak English
When I say: "One and only one...", I mean that you should not put several different plants together in a shitakusa, otherwise it becomes a kusamono.
In traditional bonsai, the Kusamono does not accompany the bonsai, it is only the shitakusa
