I created this cutting last year, and before the beginning of winter, I separated it from the parent plant, and planted it with sphagnum moss intact, into a pot. I didn’t know how much roots have developed, all I could see was some roots on the outside parameter. Since the Shimpaku has started to put out growth, I’ve decided to pot it up into a colander.
I first took it out of the terracotta pot, removed all the sphagnum moss and combed out the roots, such that they radiate from the trunk. Over time, this would ensure a good nebari.
After lining up all the roots radially from the trunk, I secured the tree in place with a wire, and then filled in with bonsai soil. This tree will be growing in this colander for a long time until it’ll need another repot.
