I bought this Chinese Elm Bonsai yesterday and it came in a traditional glazed square pot. It was too small and the plant was very rootbound. So I repotted it in a larger pot but in all the pictures online I've seen of it its usually in flat wide pots. I have a spare flatter, wider pot and saucer which is next to the plant in the picture.
Should I put it in the spare pot or keep it in its current pot? I could trim its roots and put it back in its original traditional pot and saucer it came with though
