i just purchased a healthy trident maple from a bonsai nusury. i was wondering what i should do with it. should i plant it directly into a bonsai pot or should i change it into a somewhat larger pot that will let it continue to grow and get stronger before doing rot triming and other stuff. i have made some pictures of my trident maple to possibly help you tell if it's ready for a slightly bigger pot, plus it has roots growing out of the bottom of the pot. comparing the pot size to a pencil -->
