Last year I potted this Shimpaku into a colander hoping that it’ll develop more roots. Unfortunately, due to the bad potting medium, and its propensity to breakdown easily, the Shimpaku didn’t develop as much roots as I wished.
Nevertheless, it still provides sufficient fine roots for a healthy root ball. I got a pot from David Johnson last summer, especially for this tree. After potting it into the new pot, it seems like a great match. I think I’ll keep it growing in here for a while. Due to the small root mass, the tree is a bit shaky even after the cork-screw method of holding it down. Since the tree won’t be moved, I won’t stress over it. I’ll just let it grow its way into being more stable.
