No need to pot on as the re will just grow bigger, If you must do this treat
it like a big tree and keep root disturbance to a minimum and keep the tree
in it's root ball.
The bigger the pot the bigger the tree which defeats the object of Bonsai.

I have purchased a bonsai plant recently.

After having read all the care instructions, I am still left with some
queries.

Does one need to pot on?

If so, do I go for the next size up?

When should I pot on, if necessary?
