So, first the wiring, and later, the shari. That makes sense, since in the earliest stages, when the trunk is very thin, it is too early to create the shari. Wiring is what creates some good curves. Later, when the trunk has some volume, the shari can add to the contorted shape.
Since Ross mentioned the Lindsay Farr video, this is a question that is not related to the shimpaku, but I hope I will be forgiven for asking: There was a black pine growing field with thousand of young black pines. How ofter are they root-pruned? Every 2 to 3 years, or may be they grow much longer before getting root-pruned? Does somebody have any idea how they do this? I prune mine every 3 years, and I thought that it is not a good idea to grow them longer without root-work, but I wonder how they do it in Japan?
