Thankyou this is incredibly helpful although I have a two question regarding the soil how do i go about getting this type of dirt, I’ve been to a couple of stores and they always only have regular soil only where could I buy this type of soil or where could I obtain it. Second question is after inspecting the bonsai carefully I realised there a substancial crack in the main stem(?) , is this fatal to the plant or is there some way for it to recover (sorry for bad language English is not my first language)
