I was told the tree was also planted in everyday planing soil, which I've read isn't exactly meant for bonsais. Should I change out the soil when I move it to a new pot, or should I save that for when it gets a bit bigger and when it would be more likely to survive the transition?
I'm curious for how long it has been into a pot without any drainage holes, if it's rootbound it's been a while, if it's wobbly it was potted in there not long ago, that's why I'm asking.
If it's rootbound and without any drainage I would consider sliding to a bigger pot, without any rootwork at all.
If it's wobbly, it's difficult for me to say what I would do, maybe I would try to drill some holes without disturbing the tree, so I could wait for next repotting season.
About soil, generally nurseries use common soil, if can afford a slightly better soil, it's good, but not like the extra expansive soils you know... HOWEVER repot with new soil is not done by this time of year on northern hemisphere.
I think the existing pot is mainly for home decor, and not specifically made for holding plants, so I'm not sure if it will drill real well. It doesn't look like we got as much rain as I thought so I think I might just give the tree a few days to dry out and see if I can transplant it midweek.
