Al,
sorry, I couldn't resist teasing you. Kokufu, man more power to you.
Beautiful efforts by the way.
Have you thought about trying this, take one of those cuttings and place in a coarse soil mix, in a long container [ we used an umbrella stand, it was plastic ] and let the roots grow.
Then redo the process of the root cutting on the shapes you get out of the mix.
Gives amazing trees.
Also works on Fukien tea and the Chinese snow rose and quite a few other plants.
We don't seal the cuts as they heal naturally, as the plant grows.
Will send some images in a day or two.
Good Day
Anthony
