Hm.. The ever lasting dicussion on when a plant goes in a bonsai pot. For me, as long as the main branches have not set, they stay in a large pot, allowing good growth & health. It looks a little ugly on the benches -Out of my ~120 trees only some 20 are in nice pots- but I believe this is a long-term hobby and not a sprint to quickly get something in a nice pot. And the trees are mostly too big to just put them in a bigger pot for development.
