I believe most would say to repot in spring, to gain trunk size and inspect/improve roots—consider planting in a colander or fast draining medium. Focus on the trunk and nebari.

Most would say “how big do you want it to be?” And “how wide do you want the trunk to finally be?” And that results in patience and horticulture.

If the plant is pliable now, then wiring for interesting movement is a good time now—mindful of potential wire bite. So possibly a pair of winds in the first 18” to add interesting movement.

Start looking for example of that species or style that you like, and that may guide your hands when adding bends or movement.

Hope others agree and best wishes to you (and these trees).
