While I love the oval Koyo and think it’s a great fit for showtime, it is a bit too small for daily use.
This year, it was reported into a wider, shallower vintage Heian Kouso pot.
Minor root work; simply combed out the very fuzzy roots (which grew up and into the fertilizer cakes used this year), and removed some large downward-facing roots from the bottom.
Fresh soil (akadama and lava 2:1) was worked in, and top-dressed with some small grain akadama.
Since it has started growing already (work done on Feb 10), it will need to be protected from the inevitable sub-freezing nights we will have over the next 3-5 weeks. It is also time to apply lime-sulfur to fight against aphid and cedar-Apple fungus which plagues this tree.
