hi! i'm pretty new to bonsai and i have a couple of questions. i got a bonsai for christmas, and the good news is, it's from a good nursery and it seems to be healthy. but the bad news is i have no idea what to do with it. i got a book with it too, and it doesn't look much like any of the types/formations illustrated, so i was wondering how i should prune it?
you can see better in the second photo, that there's just one main branch that is almost curving back intowards the tree at the moment. so is it a bad idea to cut back a branch that big? or should i try and wire it up or down or something?
also it's summer here at the moment so its growing well and getting lots of sun but some of the leaves underneath are getting yellow or brown, is that just from lack of sun? and if so, what is the best way to trim just the leaves? ie clippers, fingers, etc. and how far back should i trim it?
thanks for your help <3
